Shoreham Weather

Eventually Extremely Warm

The average maximum temperature during June 2026 in Shoreham was 22.2 Celsius (72F), which was 0.8 Celsius (1.5F) above the 10-year average. This was the 2nd highest average maximum for June in the area since before 1880. Only June 2023 was warmer. The average minimum temperature was 14.8 Celsius (59F), which was 1.8 Celsius (2.7F) above the 10-year monthly average. This was the highest average minimum since records began. Overall, it was the 2nd warmest June, behind the June of 2023. Interestingly, since 1880, the 3 warmest Junes have all occurred during the last 4 years.

The highest temperature measured during the month was 37.1 Celsius (99F) on the 25th. This was the hottest day in the area since before 1880. Although the weather station is not on a site officially recognised by the Met. Office, the maximum temperature was probably bona fide. A site 2 km to the east, but 200 m closer to the coast, had a high of 36.9 Celsius (99F), and it was the sea breeze that was the governing factor in this remarkable event. As seen in the graph below, the temperature was capped by the southeasterly breeze, but the return of the east-northeasterly, blowing across over 10 km of urban development, in the late afternoon, was enough to take the temperature into uncharted territory for June. Merryfield (Somerset) claimed the ‘official’ maximum for the day, and for June, with a high of 36.7 Celsius (98F). However, that record only stood for a day as Santon Downham (Suffolk) recorded 37.3 Celsius (99F) on the 26th.

After the 25th, other maxima almost pale into insignificance; nevertheless, the 35.7 Celsius (96F) recorded on the 24th was higher than the previous UK June high of 35.6 Celsius (96F) recorded in Southampton in 1976. Highs of 32.5 and 31.2 Celsius (91 and 88F) occurred on the 23rd and 22nd, respectively. The 21st and 27th were the only other days with highs above 25 Celsius (77F), although a further 11 days had maxima above 20 Celsius (68F). All of the warm weather occurred during the second half of June. In fact, there were no maximum temperatures above 20 Celsius (68F) before the 14th, and no maxima below 20 Celsius (68F) after the 13th. Although there were no particularly cool days, the average maximum temperature for the first half of June was 3 degrees Celsius (>5F) below average. There were 3 days when the temperature failed to reach 17 Celsius (63F). The 9th, 10th and 11th had highs of 16.9. 16.4 and 15.4 Celsius (62, 62 and 60F), respectively.        

There were many warm nights during June, including 4, so-called, tropical nights when the temperature failed to fall below 20 Celsius (68F). The warmest night was the 26th, with a minimum of 23.3 Celsius (74F), but although this was a record at this site in Shoreham, other places in the UK had warmer nights. The minimum on the 26th occurred late in the night as the gentle northeasterly wind veered south to southwesterly. Earlier in the night, the temperature was exceptionally high. After an evening when the temperature hovered between 28 and 29 Celsius (82-84F), a rise occurred after midnight, this peaking at 29.9 Celsius (86F) at 0100 hours. Other minima during this exceptional spell of warmth were 21.9, 21.1 and 20.0 Celsius (72, 70 and 68F) on the nights of the 24th, 25th and 23rd respectively. A further 3 nights, the 22nd, 27th and 28th, had lows above 18 Celsius (64F). On most other nights (20) the minimum ranged from 10 to 16 Celsius (50-61F), with the lowest values generally occurring early in the month. There were 3 cooler nights. The 9th, 10th and 11th had lows of 8.7, 9.9 and 9.1 Celsius (48, 50 and 48F). 

The sea temperature ranged from 16 to 18 Celsius (61-64F) during the first 3 weeks of June, but then rose to 19 or 20 Celsius (66-68F).

Frost

There were no frosts during June. The lowest grass temperature was 5.0 Celsius (41F) on the 9th.

Rain

Rainfall during June amounted to 47.0  millimetres (1.85 inches), which was 17% above the 10-year monthly average. Measurable rain fell on 16 days, which was 6 days above normal for June, and wet days (when 1 millimetre (0.04 ins.), or more, of rain falls) numbered 11, which was 4 days above average for the month. Rain commenced on the evening of the 1st, and by 0900 GMT on the following morning 16.0 millimetres (0.63 ins.) had fallen, which was more than one third of the monthly total. There were no completely dry days between the 2nd and 11th, but much of the rain was light, and only 4 days had totals above 2 millimetres (0.08 ins.). The wettest of these was the 3rd, 7th and 11th with 6.2, 5.6 and 4.8 millimetres (0.24, 0.22 and 0.19 ins.) respectively. Between the 12th and the end of the month only 4.2 millimetres (0.17 ins.) of rain fell with just 1 wet day. That was on the 18th when 2.4 millimetres (0.09 ins.) were measured.

Hail

On the 18th, there was 1 clap of thunder early in the afternoon, and there were several rumbles of thunder from high-level castellanus cloud early in the morning on the 23rd, but with no rain. Thunder and lightning occurred for around 90 minutes late on the evening of the 26th, but with no measurable rain. Further thunder occurred in the early hours of the 27th, and again during the evening, but both events only produced a total of 12 millimetres (0.04 ins.) of rain.

Snow

No sleet or snow was observed in this part of Shoreham.

Wind

Perhaps surprisingly, June was a southwesterly month, with winds from between south and west dominant on two-thirds of the days, although there was a marked difference between the cool and brisk sou’westers that often blew day and night early in the month, and the light winds that morphed into afternoon sea breezes during the second half of June. At Shoreham Airport, southwesterly winds gusted to 32 knots (37 mph) on the afternoon of the 2nd, and the 3rd, a very windy day for the time of year, had a gust of 41 knots (48 mph) during the afternoon, and strong winds then continued into the 4th, with 39 knots (45 mph) recorded during the afternoon. After a lull on the 5th, several southwesterly gusts exceeded 40 knots (46 mph) on the afternoon of the 6th, with a peak gust of 42 knots (48 mph) mid-evening. Southwesterly gusts reached 33 knots (38 mph) on the afternoon of the 9th, with a similar direction and peak gust on the afternoon of the 11th. No further gusts above 30 knots (34 mph) occurred during the remainder of the month.

Thunder

No thunder was heard in this part of Shoreham.

Snow

No sleet or snow was observed in this part of Shoreham.

Wind

Atlantic weather systems continued to track eastwards at a lower latitude than normal, with their parent low-pressure areas often slowing and decaying over the southern parts of the British Isles. In Shoreham, the average daily pressure reading was 15 millibars below normal, a similar negative anomaly to January. Southwesterly winds were dominant, accounting for around 36% of daily readings. Both southeasterly and northwesterly winds were dominant on 18% of days, with most of the rest of the month cyclonic variable. No exceptionally windy days occurred, but it was often breezy during the first and third weeks of the month. However, at Shoreham Airport, the first gusts above 30 knots (34 mph) did not occur until the afternoon of the 16th, when west to northwesterlies gusted to 33 knots (38 mph). Gusts of 34 and 35 knots (39-40 mph) from an east to southeast direction occurred from late morning to early evening. There were no further gusts above 30 knots (34 mph) during February.

Fog

Fog patches were observed on the evening of the 25th; otherwise, it was often misty in association with drizzle, and at times, low cloud was observed shrouding the Downs.

Changeable, Wet and Rather Mild

Temperature

The average maximum temperature during January 2025 in Shoreham was 8.4 Celsius (47F), and that was around 0.5 Celsius (<1F) above the 10-year average, but over 1 Celsius (2F) above the 30-year average. The average minimum temperature was 3.8 Celsius (39F), and that was close to 0.5 Celsius (1F) above the 10-year monthly average, but more than 1 Celsius (2F) above the long-term average.

The highest temperature measured during the month was 11.3 Celsius (52F) on the 18th, but 10.9 Celsius (52F) was recorded on the 19th, and 10.7 Celsius (51F) occurred on the 17th. A further 7 days had maxima above 10.0 Celsius (50F), with all of these milder days occurring after the 11th. After the 11th, only 2 days had maximum temperatures below 9 Celsius (48F). A high of 8.4 Celsius (47F) occurred on the 26th, and 7.2 Celsius (45F) was recorded on the 29th. Before the 12th, only 1 day had a maximum temperature above 9 Celsius (48F), namely the 8th, when a high of 9.9 Celsius (50F) occurred. On 5 days early in the month, the temperature remained below 5 Celsius (41F). There were 4 consecutive cold days commencing on the 2nd, and the 10th was also cold with a high of 3.8 Celsius (39F). Highs of 3.7 and 3.5 Celsius (39-38F) occurred on the 3rd and 4th, respectively, but the coldest day of the month was the 5th with a top temperature of 2.6 Celsius (37F).        

There were no exceptionally mild nights during January, but a minimum of 9.1 Celsius (48F) occurred on the 13th, with 8.9 and 8.7 Celsius (48F) recorded on the 20th and 19th, respectively. There were 4 more nights with minima above 8.0 Celsius (46F), and a further 7 nights had lows above 7.0 Celsius (45F). All nights between the 17th and 25th had a minimum above 7.0 Celsius (45F).

Lows of 2.5 Celsius (37F) and 0.4 Celsius (33F) occurred on the 28th and 29th, respectively. At the beginning of the month, there were several cold nights. On the 4th, a low of minus 3.4 Celsius (26F) occurred, and minus 3.6 Celsius (26F) was recorded on the 5th, but the lowest temperature was on the 6th, when a minimum of minus 6.2 Celsius (21F) occurred. This was the lowest temperature recorded in any month at this site since records began in 2017, and it appears to be the lowest January temperature in this area for 15 years. At Shoreham Airport the 6th may well have been the coldest January night since 1987. 

The sea temperature was 8 or 9 Celsius (46-48F) throughout the month.

Frost

There were 7 air frosts during January. This was 1 day above average for the month. Each of the first 6 days had an air frost, although it was slight on the 2nd when a minimum temperature of minus 0.9 Celsius (30F). The other night that had an air frost was the 11th, when a low of minus 2.4 Celsius (28F) was recorded. A total of 14 grass frosts occurred during January. That was average for the month. A grass frost occurred on 10 out of the first 11 nights during January, with the other 4 occurring on the 14th, 16th, 28th, and 29th. These latter 4 grass frosts were fairly slight with grass temperatures above minus 3 Celsius (27F), but the earlier frosts were generally accompanied by much lower temperatues. On 7 nights, the grass temperature fell below minus 6 Celsius (21F), with the lowest readings of minus 9.4 Celsius (15F) occurring on the 4th and 6th.

Rain

Rainfall in January amounted to 124.4  millimetres (4.9 inches), which was around 65% above the 10-year monthly average. It was the wettest January in this area for 10 years. Measurable rain fell on 23 days, which was 6 days above normal for January, and wet days (when 1 millimetre (0.04 ins.), or more, of rain falls) numbered 17, which was 5 days above average for the month.  The month began relatively dry, with only 0.4 millimetres (0.02 ins.) of rain during the first 5 days of the new year. In fact, the 2nd, 3rd and 4th were consecutive dry days. No more consecutive completely dry days occurred during the month. On the 6th, there were 8.4 millimetres (0.33 ins.) of rain, and on the 8th, it rained for most of the day, making it the wettest day of the month with 29.0 millimetres (1.14 ins.) measured. In this very unsettled month, there were daily rain totals of 8.8 millimetres (0.35 ins.) on the 13th, 16.0 millimetres (0.63 ins.) on the 15th, 12.4 millimetres (0.49 ins.) on the 21st and 9.6 millimetres (0.38 ins.) on the 26th.

Hail

No hail was observed in this part of Shoreham.  

Thunder

No thunder was heard in this part of Shoreham.

Snow

Light snow occurred before dawn on the 5th and produced a thin layer on the ground that lasted until late morning on the 6th. Light snow, followed by sleet, occurred late morning and early afternoon on the 6th.

Wind

Atlantic weather systems tracked eastwards at a lower latitude than normal, with their parent low-pressure areas often slowing and decaying over the southern parts of the British Isles. In Shoreham, the average daily pressure reading was nearly 15 millibars below normal, and there were 10 consecutive days, beginning on the 21st, with readings below 1000 millibars. This is a new record sequence for any month at this site. Unsurprisingly, it was often windy, with the majority, around two-thirds, of the winds blowing from between southwest and northwest. On most other days, southeasterly winds prevailed. At Shoreham Airport, southwesterly winds increased late on the 6th, and gusts reached 33 knots (38 mph) in the late evening, before peaking at 38 knots (43 mph) in the early hours of the 7th. A very deep area of low pressure passed by close to Shoreham on the evening of the 8th with pressure falling at a rate of 4 to 5 millibars an hour, and with a central pressure below 968 millibars. Southwesterly winds gusted to 41 knots (47 mph) around midnight, with the following northwesterly wind gusting to 35 knots (40 mph) on the afternoon of the 9th. Southerlies, ahead of the next depression, gusted to 35 knots (40 mph) on the evening of the 11th. On the late afternoon and evening of the 15th, southerlies gusted above 30 knots (34 mph), with a peak of 33 knots (38 mph) ahead of the post-cold front southwesterlies. An increase of southerly winds on the evening of the 20th culminated in a gust of 37 knots (42 mph) just before midnight. South-southeasterly winds gusted to 33 knots (38 mph) around midday on the 21st, and winds from a similar direction reached 31 knots (35 mph) in the early hours of the 24th. Southeasterly winds gusted to 36 knots (41 mph) before dawn on the 27th, but no further gusts above 30 knots (34 mph) were reported during January.

Mild and Rather Dry

Temperature

The average maximum temperature during December 2025 in Shoreham was 10.1 Celsius (50F), and that was around 1 Celsius (<2F) above the 10-year average, but nearer 2 Celsius (3.5F) above the 30-year average. The average minimum temperature was 6.5 Celsius (44F), and that was also close to 1 Celsius (2F) above the 10-year monthly average, but more than 2 Celsius (3.5F) above the long-term average.

A further 5 nights had minima above 10 Celsius (50F), with the last of these very mild nights occurring on the 22nd. Minimum temperatures on most other nights (13) ranged from 5 to 10 Celsius (41-50F), but several cold nights occurred. Before mid-month, there was only 1 night when the temperature fell below 2 Celsius (36F). That was on the 5th, when a low of minus 0.2 Celsius (32F) was recorded. After mid-month, there were 4 such nights. The lowest temperature was minus 1.1 Celsius (30F) on the 31st, but minus 0.4 Celsius (31F) occurred on the 26th.  

The sea temperature slowly dropped from 11 or 12 Celsius (52-54F) at the beginning of December to 10 Celsius (50F) around Christmas. A further drop to 9 Celsius (48F) occurred during the last week of the month.

There were 3 grass frosts between the 17th and 20th, with the remaining grass frosts occurring between the 26th and the end of the month. The lowest grass minima on these nights were minus 3.3 Celsius (26F), which occurred on the 17th, 26th and 31st.

Rain

Rainfall in December amounted to 87.8  millimetres (3.46 inches), which was around 20% below the 10-year monthly average. Measurable rain fell on 14 days, which was 6 days below normal for December, and wet days (when 1 millimetre (0.04 ins.), or more, of rain falls) numbered 10, which was 4 days below average for the month.  The month began wet, with rain or drizzle throughout the day on the 1st, leading to a total of 6.8 millimetres (0.27 ins.). The following day was showery, with some of the showers heavy, and another 11.8 millimetres (0.46 ins.) of rain were measured. Further showers on the 3rd produced 6.6 millimetres (0.26 ins.), and in a very wet opening to December, 6.0 millimetres (0.24 ins.) fell on the 5th, 6.6 millimetres (0.26 ins.) on the 7th, and 11.2 millimetres (0.44 ins.) on the 8th. The first 8 days of December had a total rainfall of 55.0 millimetres (2.17 ins.). Only 0.4 millimetres (0.02 ins.) of rain fell on the 9th, and no measurable rain fell during the following week. The 18th was a very wet day. Much of the rain fell before 0900 GMT, and as a ‘rainfall day’ runs from 0900 to 0900, the total was split between 12.8 millimetres (0.50 ins.) on the 17th and 14.8 millimetres (0.58 ins.) on the 18th. Occasional rain fell on the following 3 days, but the highest total was only 3.6 millimetres (0.14 ins.) on the 21st. The remainder of the month (10 days) was dry.   

Hail

Small hail occurred during heavy showers early and mid evening on the 2nd.  

Thunder

No thunder was heard in this part of Shoreham.

Snow

No sleet or snow was observed in this part of Shoreham.

Wind

Atlantic weather systems regularly crossed the country during the first 3 weeks of December with southwesterly winds dominating, but with the occasional northwest wind occurring after the passage of cold fronts. Winds were often quite strong, but during the week before Christmas, pressure rose and an anticyclone developed. This was mainly centred to the north of the country, allowing gentler winds to blow from a northeast or easterly direction. At Shoreham Airport, the first day of the month was windy, with several gusts from the southwest reaching 41 knots (47 mph), and 1 in the late afternoon peaking at 42 knots (48 mph). An isolated gust of 35 knots (40 mph) occurred as a cold front moved through Shoreham late in the morning on the 4th. The evening of the 5th was very windy with southerly gusts of 44 knots (50 mph). The wind veered southwesterly, but it remained breezy, with a gust of 34 knots (39 mph) occurring in the early hours of the 6th. Late in the afternoon on the 7th, southwesterly winds gusted to 33 knots (38 mph), but after a short lull, southwesterlies gusted to 36 knots (41 mph) early in the evening on the 9th. The evening of the 17th became windy, with southwesterly gusts rising to 32 knots (37 mph) around midnight. It stayed windy through the 18th, with a top gust of 37 knots (42 mph) during the late afternoon. Although pressure rose markedly towards the end of the month, there were 2 more windy days. On the 24th, northeasterly winds gusted to 32 knots around lunchtime, and on the 25th, gusts of 34 knots (38 mph) were measured from a similar direction.

Fog

Fog was observed on 2 days during December. On the 7th, drizzle, mist and fog occurred for much of the day as mild, moist air spread north from the sea. Completely different fog occurred on the 31st, as a gentle northwest wind blew patches of freezing fog across Shoreham from the Adur river valley.
