Even though we had less sunshine on Tuesday than on previous days, also more cloud, the maximum of 23.5C was exactly the same as on Monday being 0.8C above the 35-year average. With warm nights and the dry land, is acting as a heat reservoir.

It was another dry day, evaporation now totalling 35mm, and the UV again very high.

Following a warm day and cloudy night little warmth was lost into the atmosphere so a minimum of 14.6C was not surprising being 2.8C above average, the warmest night since 25th June and up a degree on Monday.

Wednesday arrived with considerable cloud but by 08.00 the sun was beginning to break through and the temperature had risen to 16.4C.

Update on Wednesday at 15.50: heat builds again with maximum of 25.2C at 15.36, being 2.5C above average and warmest day this month equal to that on July 4th.

With fewer hours of sunshine on Monday, the wind having backed into the southwest rather than the cooler northwest, still meant that it was another warm day with the maximum of 23.5C being 0.8C above the average.

Cloud cover overnight limited warmth from the ground radiating into space so the minimum of 13.7C at 00.35 was almost 2C above the 35-year average. This was the warmest night in July.

Monday was another dry day. The rainfall recorded over the past three weeks amounted to 8.1mm whereas the equivalent rainfall lost to the atmosphere through evaporation from ground sources and plant life far exceeded this with a total of 32mm.

Tuesday initially saw bright intervals but by 08.00 the cloud cover was 8/8 completely blocking out the sun.

After a cloudy start to Sunday the sun broke through mid-morning producing 10 hours but the UV level, although still in the very high category, was the lowest this month, as was the maximum solar radiation. The thermometer rose to a peak of 23.1C at 15.50, which although the lowest for four days was still 0.4C above the 35-year average.

With no rain on Sunday the first week of June has produced just 0.3mm of rainfall.

Sunday night into Monday was a warm night with the thermometer not falling below 12.9C, being 1.1C above average.

Monday initially arrived with bright sunshine but a fog bank drifted across just after 07.15, blocking the sun and limiting visibility to 600m. By 08.00 the fog had evaporated and the thermometer risen to 14.7C with weak sunshine breaking thorough.

The June data is now updated. Apologies for the late input of the recent data.

Saturday gave us a sunny morning but advancing cloud from the next weather front obscured the sun for much of the afternoon. However, with light winds, varying between Northwest and then Northeast in the afternoon, the thermometer crept up to a maximum of 23.5C at 13.02 before the sun’s strength became dimmed, this was 0.8C above average.

It was a dry day. During the late evening much thicker cloud from the cold front passed over but produced no rain. However, another area of thick cloud traversed the area between 04.00 and 05.00 early Sunday and produced 0.3mm of light rain just before 04.30. This was the first rainfall after ten dry days.

The thick cloud meant a mild night with the thermometer not falling below 13.2C, which was 1.4C above average.

Sunday arrived with a hang back of cloud front the weather front but brief glimpses of sunshine were observed around 08.00.

Although the anticyclone had started to weaken, down 6mb, Friday gave us another hot day with a maximum of 25.1C, just 0.1C below the Thursday peak but another above average day being +2.4C.

The UV level not surprisingly reached the very high level again although sunshine hours were reduced compared to previous days due to transient high cloud but 11.6 hours were recorded.

Friday night into Saturday was cooler as clear skies allowed warmth from the ground to radiate into the atmosphere producing a minimum just after dawn (05.10) of 8.8C, which was exactly 3C below the July average.

We were greeted on Saturday morning by strong sunshine that by 08.00 had lifted the thermometer to a reading of 18.9C. However, advancing cloud from the next weather front is advancing from the north and can be seen seen as broken cloud in the northern sky and is expected to reduce sunshine from around mid-morning as it approaches from the north west.
