UV ‘Very High’ on Wednesday – but it is mid-summer. Wind change brings a different air today.

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.
