Weather in Shoreham – August 2022

Very Warm

Temperatures

The average maximum temperature during August 2022 in Shoreham was 25.2 Celsius (77F), and that was around 3 degrees Celsius (>5F) above normal for the time of year. The average minimum temperature was 15.6 Celsius (60F), and that was more than 1 degree Celsius (2F) above the August average. Overall, it was the warmest August since 1995, with only 2 other Augusts comparable since 1880, namely the Augusts of 1947 and 1990.

The highest temperature recorded during the month was 32.8 Celsius (91F) on both the 12th and 13th, but maxima were also above 30 Celsius (86F) on the 10th and 14th, with values of 30.5 Celsius (87F) and 31.2 Celsius (88F) respectively. On most days (19) maximum temperatures ranged between 23 and 27 Celsius (73-81F), but there were a few less warm days. Remarkably, though, there was only 1 day when the temperature failed to reach 21 Celsius (70F). That day was the 17th when a maximum of 20.7 Celsius (69F) occurred.

There were many warm nights during August, and on 7 occasions the temperature remained above 18 Celsius (64F). However, only 1 of these warmer nights had a minimum above 19 Celsius (66F). On the 19th, a low of 19.1 Celsius (66F) was recorded. A further 5 nights had minima between 17 and 18 Celsius (63-64F). No cool nights occurred during August, although on 9 nights the temperature fell below 14 Celsius (57F). Only 1 of these less warm nights had a minimum below 12 Celsius (54F): on the 7th, a low of 11.3 Celsius (52F) occurred. 

The sea temperature was between 20 and 22 Celsius (68-72F) throughout the month.

 

Frost

 

There was no frost in Shoreham during August. The lowest grass temperature was 8.3 Celsius (47F),  recorded on the 7th. 

 

Rain

 

Rainfall in August amounted to 69.4 millimetres (2.7 ins.), which was very slightly above average for the month. Measurable rain fell on 7 days, which was 6 days below the average, and wet days (when 1 millimetre (0.04 ins.), or more, of rain falls) numbered 6,  and that was 3 days below the average. Although there was a little rain on each of the first 2 days of August, it was not enough to measure, and no further rain fell until the early hours of the 16th. It was the first measurable rain for 21 days. The rain on the morning of the 16th amounted to 27.2 millimetres (1.07 ins), but 5.6 millimetres (0.2 ins.) of the total fell before 0900 UTC, and thus was assigned to the 15th. Further bursts of heavy rain fell on the morning of the 17th and gave 6 millimetres (0.2 ins.) of rain, and although 4 out of the following 6 days were dry, another 4 millimetres (>0.15 ins.) were added to the monthly total. Heavy rain overnight on the 24th/25th resulted in 29 millimetres (1.1 ins.) allocated to the 24th, and 3.2 millimetres (0.12 ins.)  to the 25th. No measurable rain fell on the last 6 days of August.  

 

Hail

No hail was observed in this part of Shoreham.

 

Thunder

Thunderstorms occurred on 3 days during August. On the morning of the 16th, thunderstorms lasted for over 3 hours, with thunder also occurring on the following day around lunch time. A few rumbles of thunder also occurred on the 25th in the early hours of the morning.

 

Snow

 

No sleet or snow occurred in Shoreham.

 

Wind

 

Pressure was higher than average across southern Britain, but with the centres usually positioned to the south of the country, it meant winds were often from between southwest and northwest, with breezes from these quadrants accounting for about half of the daily readings. The high sea temperatures did little to lower air temperatures when southwesterly sea breezes developed, and when north or northeasterly occurred (just over a quarter of the daily observations) it was invariably warm or hot. At Shoreham Airport, there were no gusts over 25 knots (29 mph) during August.      

 

Fog

 

No fog was observed in this part of Shoreham.

Very Dry and Warm

Temperatures

The average maximum temperature during July 2022 in Shoreham was 24.6 Celsius (76F), and that was over 1 degree Celsius (>2F) above normal for the time of year. The average minimum temperature was 15.0 Celsius (59F), and that was less than 0.5 degree Celsius (<1F) above the July average.

The highest temperature recorded during the month was 34.7 Celsius (94F) on the 19th, but the only other day with a high above 30 Celsius (86F) was the 18th, when the temperature peaked at 31.2 Celsius (88F). There were 11 days with maxima between 25 and 30 Celsius (77-86F), with 7 of those warmer days occurring between the 7th and 14th. No especially cool days occurred during July, however, on 8 days the temperature failed to rise above 23 Celsius (73F). The 25th and 26th were 2 of the somewhat less warm days, with the first few days of the month accounting for the remaining 6 days. The coolest days were the 2nd and 3rd with maxima of 20.5 Celsius (69F), and also the 1st. On this day, the maximum temperature was 19.2 Celsius (67F).

There were several warm nights during July, none more so than the 19th,  when a minimum of 22.9 Celsius (73F) was recorded. This was the warmest July night in the area for at least 140 years, and during much of the night the temperature hovered between 25 and 26 Celsius (77-79F). No other minima were close to this value, but on 5  nights the minimum temperature was between 18.0 and 18.2 Celsius  (64-65F). On most days (16) the minima were between 13 and 17 Celsius (55-63F), but there were a few cooler days. However, only 2 days had minimum temperatures below 12 Celsius (54F). On the 1st, a low of 10.8 Celsius (51F) occurred, and on the 3rd, the temperature dipped to 10.7 Celsius (51F). 

The sea temperature was 19 Celsius (66F) at the beginning of the month, rising to 20 Celsius (68F) by mid month, with 20 or 21 Celsius (68-70F) then maintained for the remainder of the month.

 

Frost

 

There was no frost in Shoreham during July. The lowest grass temperature was 10.0 Celsius (50F),  recorded on the 1st, 3rd and 10th. 

 

Rain

 

Rainfall in July amounted to 8.6 millimetres (0.34 ins.), which was less than 20% of average for the month. Overall, it was the driest July in the area for 12 years.  Measurable rain fell on 4 days, which was 6 days below the average, and wet days (when 1 millimetre (0.04 ins.), or more, of rain falls) numbered 2,  and that was also 6 days below the average. Although there was a heavy shower in the early hours of the 1st, the resulting rain was before 0900 hours UTC, and therefore added to the total for the preceding month. Otherwise, the first 16 days of the month were dry. Short bursts of heavy rain overnight on the 17th/18th gave 1.8 millimetres (0.07 ins.), and further showery rain on the evening of the 19th added 0.8 millimeters (0.03 ins.) to the total. Showery rain occurred again from late morning until early afternoon on the 22nd. This added 5.8 millimetres (0.23 ins.) to the monthly total. The only other measurable rain was the 0.2 millimetres (0.01 ins.) that fell overnight on the 24th/25th.  

 

Hail

 

 

No hail was observed in this part of Shoreham.

 

Thunder

 

Thunderstorms occurred on 3 days during July. There was thunder and lightning to the west for 40 minutes on the evening of the 17th. A few rumbles of thunder occurred early to mid evening on the 19th, and finally, there was thunder late morning and early afternoon on the 22nd.

 

Snow

 

No sleet or snow occurred in Shoreham.

 

Wind

 

Pressure was higher than average across southern Britain, but with the centres usually positioned to the south of the country, it meant winds were predominantly from between southwest and northwest, with breezes from these quadrants accounting for over half of the daily readings. On about a quarter of the days, winds were mainly between southeast and northeast, with the remainder of the days having light and variable winds. Generally,  winds were light, but southwesterly sea breezes were moderate or fresh at times in the afternoons, especially in the first and third weeks.  At Shoreham Airport, there was a gust of 33 knots (38 mph) from the west-southwest early on the evening of the 19th as a cold front pushed the hot air eastwards into the continent, and southwesterly gusts of 30 to 31 knots (34-35 mph) occurred on the morning of the 25th; but these were the only gusts above 30 knots (34 mph) during July.      

 

Fog

 

No fog was observed in this part of Shoreham.

Measurable rain fell on 16 days, which was 6 days above the average, and wet days (when 1 millimetre (0.04 ins.), or more, of rain falls) numbered 13, and that was also 4 days above the average. A heavy shower on the afternoon of the 1st gave 3.0 millimetres (0.1 ins.) but the 2nd was dry day. However, the following 7 days each had measurable rainfall, with daily totals of 5.8, 4.8, 10.6 and 7.4 millimetres (0.2.0.2.0.4 and 0.3 ins.) on the 3rd, 4th, 7th and 8th respectively.

Wind

 

Pressure was higher than average across southern Britain, but with the centres usually positioned to the south of the country, it meant winds were predominantly from between southwest and northwest, with breezes from these quadrants accounting for well over half of the daily readings. Although there were no particularly strong winds, sea breeze enhancement gave several cool and blustery afternoons at the beginning and end of the month, with the lightest winds generally occurring around mid month. At Shoreham Airport, a squally gust of 36 knots (41 mph) from the southwest occurred on the afternoon of the 8th. On the 18th, thundery weather in the evening, was accompanied by rapid rises and falls of pressure along with some notable downdraughts from a northerly direction (although the storms were tracking in from the south). The highest gusts recorded were 37 knots (42 mph) early and mid evening. No further gusts above 30 knots (34 mph) occurred, but several afternoons at the beginning and end of June had southwesterly gusts between 25 and 30 knots (29-33 mph).

There were no warm nights during May, but a minimum of 14.0 Celsius (57F) occurred on the 19th, and 13.9 Celsius (57F) was recorded on the 27th. The 10th and 16th also had minima above 13 Celsius (55F). A combination of brisk breezes and cloud cover often prevented night-time temperatures from falling significantly. As a result, a further 11 nights had minimum temperatures above 10 Celsius (50F), and only 8 nights had minima below 8 Celsius (46F). The coolest night was the 9th with a minimum temperature of 5.9 Celsius (43F). 

The sea temperature rose slowly from 12 Celsius (54F) at the beginning of May, to 15 Celsius (59F) at the end of the month.

Frost

 

No air frost occurred March, but 10 ground frosts were recorded, and that was slightly below average for the month. Apart from on the 7th, when a grass minimum of minus 1.7 Celsius (29F) occurred, all the grass frosts were logged between the 14th and 25th. On most of these ground frost nights (6) the grass frost was slight with minima higher than minus 2 Celsius (28F).

Rain

 

Rainfall in March amounted to 30.4 millimetres (1.2 ins.), which was around 40% below average for the month. Measurable rain fell on 8 days, which was 8 days below the average, and wet days (when 1 millimetre (0.04 ins.), or more, of rain falls) numbered 6, and that was 5 days below the average. The first day of the month was very wet, and the 14 millimetres (0.55 ins.) that fell amounted to almost half the monthly total. Further rain fell early on the 2nd, but it amounted to less than 1 millimetre (0.04 ins.) after which there was no measurable rain for the following 8 days. A brief unsettled spell occurred towards the end of the second week and around mid-month, which resulted in rain falling on most days, but with daily totals unexceptional. On the 11th, a total of 5.6 millimetres (0.22 ins.) was recorded, and on the 16th, there were 5.2 millimetres (0.2 ins.). Between the 18th and 29th, no measurable rain occurred, but light rain added 1 millimetre (0.4 ins.) to the monthly total on the 30th.

 

Hail

 

Light showers of soft hail occurred late in the morning on the 31st.

 

Thunder

 

No thunder was heard in this part of Shoreham.

 

Snow

 

A light sleet shower occurred late morning on the 31st March, which
was the first wintry precipitation since sleet and snow fell on the evening of the
28th November. Interestingly, no wintry precipitation occurred during the winter
months (December, January and February).

 

Wind

 

High pressure was dominant during much of March with pressure readings some 7 millibars above the March average. As a result, winds were much lighter than usual, and only 1 day, the 14th, had winds from the ‘prevailing’ southwesterly direction. On most days (17) winds blew from between south and east, but occasionally there were northwest or northeast winds, these mostly occurring at either end of the month.  At Shoreham Airport, the only day that had gusts exceeding 30 knots (34 mph) was the 31st, when northerly gusts during the afternoon reached 37 knots (42 mph).    

 

Fog

 

Low cloud descended to ground level and produced fog around mid-morning on the 1st, and patchy fog occurred early on the 28th.
