UV Very High on Wednesday

Although the sunshine hours were reduced from previous days with 6.78 hours the UV level spiked very high at 13.00 and again at 13.30 although it was at that level for two hours.

The westerly wind was very strong increasing to a peak of 27mph at 14.27 only beginning to die down in the early evening. This wind from a cooler wind drection meant a below average day with a maximum of 17.6C (-2.5C).

The minimum of 11.5C was almost exactly that of the previous night and 1.5C above average due to the extensive cloud cover.

The moist Atlantic air prevailed on Tuesday morning with total cloud cover that brought brief, little light drizzle at 06.30 but not measurable hence recorded as a ‘trace’. However, due to the depression moving away over the North Sea, the wind had almost completely died down.

Sunshine and showers

Sunday saw rain bands crossing the area driven on by the brisk south westerly wind that brought frequent showers totalling 1.9mm. That brought the June total to 83.3mm been 30mm above the 36-year average.

Due to the frequent rain bands and brisk wind it was a cool day with the thermometer not ring above 18.1C, which was 2C below average. The bursts of sunshine between the showers, amounting to 7.9 hours, did produce a UV level that was again in the ‘High’ category.

Overnight the cloud cover meant an above average minimum of 11.6C (+1.6C).

The start to Monday was predominantly cloudy with the wind still strong from the south west. We are still under the influence of an Atlantic air mass with the deep low pressure centred over Scotland continuing to bring bands of rain although diminishing in frequency.

Atlantic air mass now in control

Saturday was such a contrast with recent dry, hot days as the thermometer did not get above the average June maximum with a peak of 19.4C (-0.7C) in the brisk south south west wind gusting more strongly to 26mph.

Rain showers were in evidence producing another 7.4mm of rainfall. This brought the total for June to 81mm.However, due to the recent hot, dry days evaporation reached the equivalent of 91mm of rainfall lost to the atmosphere.

The wind veered into the south west late afternoon and gusty as the showers passed through.

Sunday morning was predominantly cloudy with the occasional brief glimpse of sunshine that lifted the minimum of 10.2C, almost exactly average, to 13.2C at 08.00

Heatwave breaks down

The heat on Friday again was intense reaching a peak of 27.6C at 13.19, down 4C on the Thursday maximum but still 7.5C above average. In the early afternoon a change was observed as the wind veered from the southeast into the south and the temperature began to ease downwards. The was due to the change from c=hot, dry Continental Air Was to the cooler, moister Atlantic Air Mass.

In the early hours of Saturday the first rain band arrived producing 3.0mm of rainfall. The minimum overnght was at 01.33 dropping to 13.7c being 3.7C above the average.

Saturday morning was a distinct change from previous mornings in the past week as we were not greeted by strong sunshine but total cloud cover and occasional brief showers of light rain and drizzle.

The barometric pressure is at its lowest since 6th June as we are now under the influence of a depression to the north west of the UK.

Hottest day, night also morning at 08.00 and soil this month

The thermometer rose steadily throughout Thursday to reach a maximum of 31.4C at 15.30. This was the hottest day since 25th July 2019 (32.6C) and 11.3C above average. The UV level being ‘High’ for much of the morning and late afternoon rose to 7.4, which was ‘Very High’ between 12.00 and just after 14.00.

The past night has been very warm with the thermometer not sinking below 16.3C being 6.3C above the average.

Friday arrived with variable sunshine through breaks in the cloud. However by 08.00 there was more continuous sunshine that had raised the air temperature to 22.9C making it the hottest morning in June and the hottest start to the day at 08.00 since 19th June 2017. With the hot days and very warm nights it was not surprising to note the soil temperature, at a depth of 5cm, rising recently and today registered 24.7C at 08.00
