A mere 11 millimetres (0.43 ins.) of rain fell on the 8th, but from the 9th until the 13th no measurable rain fell. However, during this period there were 2 days with dew adding to the monthly total. The 0.8 millimetres (0.03 ins.) of dew was unusual, but this remarkable month continued with further heavy rainfall. On the 15th, 25.4 millimetres (1.00 ins.) fell, and the following day was the wettest of the month with 37.8 millimetres (1.49 ins.) recorded. After 2 dry days, the remainder of the month was fairly unsettled, but daily readings were somewhat lower,  although dew produced another 0.4 millimetres (0.02 ins.) of precipitation. Between the 17th and the end of the month 52.4 millimetres (2.06 ins.) were recorded, with daily totals of 11.8 millimetres (0.46 ins.) on the 21st and 17.0 millimetres (0.67 ins.) on the 26th.

Wind

 

In this very changeable month, strong winds were frequent, especially during the first 3 weeks of November. The early hours of the 1st were particularly windy with several mature trees in the area toppled over by the squally wind. On the 1st,  at Shoreham Airport, many southwesterly gusts exceeded 40 knots (46 mph) with a peak gust of 59 knots (67 mph) occurring in the early hours.  The 2nd was also windy with 40 knots (46 mph) from the southwest recorded in the early evening.  A gust of 38 knots (43 mph) occurred early on the 3rd before the wind finally decreased later in the morning. Southwesterly winds increased again on the 5th, with gusts of 33, 34, 35 and 40 knots (38-46 mph) on the 5th, 6th, 7th and 8th respectively.   There was no let-up as southwesterlies gusted to 37 knots (42 mph) on the morning of the 9th, but then pressure began to rise and wind speeds gradually decreased. On the 15th, another deep depression to the west was responsible for some strong south to southwesterly winds which peaked at 41 knots (47 mph) during the early evening. It was particularly blustery at times and a gust of 44 knots (50 mph) occurred early on the 16th. Overnight on the 17th, a gust of 38 knots (43 mph) occurred before a quieter spell of weather began. This lasted until the 21st when a deepening depression crossed southern England and produced squally winds, initially from the southeast, these veering to the west. Gusts of 37 and 38 knots (42-43 mph) occurred. Southwesterly gusts of 36 knots (41 mph) occurred on the evening of the 23rd, with 39 knots (45 mph) recorded on the following evening. The last bout of southwesterlies during the month gave 32 knots (37 mph) in the early hours of the 27th.

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.

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).
