The wind on Thursday had already veered into the north and was brisk, gusting to 20mph. As a result of the cooler air from this direction the maximum was 1.4C below average at 18.6C. However, there were 12.3 hours of strong sunshine with the UV level again in the ‘Very High’ category.
On this day last year we were at the peak of a mini heatwave when a record high for June was set with a maximum of 32.2C.
Clear skies overnight and the cooler air meant that the thermometer tumbled to a minimum of 5.8C at 04.00 this morning, being 4.2C below average.
Glorious sunshine arrived as soon as the sun got up this morning that picked up the temperature to 12.1C at 08.00.
The maximum on Wednesday was 21.8C being 2C above the average but far lower than the peak on this day in 2017 when we were in the middle of a heat wave, which on that day reached 30.8C.
During the 3.4 hours of sunshine on Wednesday the UV reached into the upper levels of ‘Very High’ not seen since 16th July 2017.
No rain fell yesterday with the total for June still 5.3mm. With little substantial rainfall forecast for the remainder of the month will June 2018 break the record for the driest on record, which currently stands at 12.5mm in June 1995 for this station?
The wind veered from the west into the northwest just before midnight bringing cooler and drier air so that the minimum fell to 8.6C with humidity down to 74% at 08.00 rather than in the 90’s.
Thursday update at 16.45: wind shift now from northerly direction and brisk, maximum of 20mph, limited peak temperature to 18.6C but much strong sunshine in the clearer air.
Tuesday’s maximum peaked at 23.2C being 3.2C above average, but this day in 2017 was a scorcher with 31.4C
There was no rain yesterday. The wettest day for this date in June was in 2007 with 7mm. This year the June total is only 5.3mm.
Tuesday produced just 1.36 hours of strong sunshine yet this date in 2007 gave us 11.47 hours.
With an overnight minimum of 15.3C due to much cloud cover and warm air from the Azores, it was the warmest night since 23rd August 2017.
Wednesday has arrived with broken cloud and occasional, brief glimpses of the sun.
The Azores High caused much warmer air to arrive on Monday raising the maximum to 21.1C, which was 1.1C above average.
We enjoyed 3.9 hours of strong sunshine, predominantly in the morning, before cloud began to arrive from the west as another weather front approached. The UV level reached 8.7 at 13.51, which was ‘Very High’ and the highest since 16th July last year.
The cloud cover and warmer air meant a very mild night in that the thermometer did not fall below 14.9C, which was 5C above the 34-year average.
There were a couple of very light showers before and after midnight amounting to 0.6mm. Rainfall now totals 5.3mm whereas evaporation from ground and plant life is the equivalent rainfall of 53mm.
Tuesday morning was the warmest since 23rd August with the thermometer reading 17.0C at 08.00
Tuesday update at 18.30: late sunshine raises temperatures to 23.2C, the warmest day for a week
Sunday was almost sunless except for a very brief glimmer that momentarily triggered the sunshine recorder for 1 minute. Due to the lack of sun and heavy cloud it was a cool day with the thermometer only reaching 16.6C, which was 3.4C below the 34-year average.
Not surprisingly it was another mild night with a minimum of 13.1C being 3.1C above average. The variation between night and day was therefore only 3.5C, a minimal diurnal temperature range for a late spring day.
Brief, light rain/drizzle fell before midnight although as the previous night, the total was limited with just 1.1mm.
Monday has arrived with cloud and light drizzle from the remains of the weather front transiting from west to east so no sun by 8.00.
Monday update at 15.30: warmest day for four days with peak of 21.1C at 15.01 before thickening cloud obscures the sun and temperature drops by 1C.
Update at 18.30: UV level ‘Very High’ and at 8.7 the highest level since 16th July 2017.
