We have to look back in the records to find that the maximum temperature yesterday, of 26.2C, was the warmest day since August 24th 2016. It was almost 10C above the May average, reached just after 3pm. All this fine weather due to a plume of continental air.
The strong sunshine amounted to 9.62 hours, the second highest total this month, which pushed the UV level into the ‘Very High’ category again.
The dry, warm spell has meant that the rate of evaporation from ground sources and plant life now exceeds 4mm/day with the total for May of 68.1mm exceeding the above average rainfall total of 67.3mm.
Overnight the thermometer fell slowly to a minimum of 11.8C at 05.25 but picked up quickly to reach 16.8C at 08.00, when readings are taken.
This morning the sun was strong as soon as it rose above the horizon with the promise of another fine day. However, the barometric pressure is falling so this will probably be the last of the days with high sunshine and UV readings.
