The mini heatwave reached its peak yesterday with a maximum of 25.3C just after 3pm. The record for May was set in 2010 with a peak of 27.8C on the 24th. There were 8.8 hours of strong sunshine.
The night has been very mild with a minimum of 13.9C due to the thick cloud cover that produced a few drops of rain just after 08.00. It is the warmest morning since last August with a temperature of 15.2C at 08.00.

The warm continental air boosted the maximum yesterday to 22.4C. Overnight cloud cover kept the temperature up with a minimum of 11.8C and a temperature at 08.00 of 15.1C, the warmest morning since last August. The UV level is still in the High category.

Yesterday was the hottest day since September with a maximum of 22.7C (72.9F) at 15.15. Most of the day the sun was partially obscured by high level cloud so the strong sunshine (100 watts/sq. meter) total was only 1.74 hours whereas the Global Sunshine (direct and reflected component from the rest of the sky) totalled 12.3 hours. The UV level again fell into the High category.
The temperature at 08.00 was 12.8C, the warmest for five months, with hazy sunshine.

The south-easterly winds continued to bring warm air yesterday that resulted in a maximum of exactly 20.0C. The 12 hours of strong sunshine was less than the previous day due to thin high cloud in the afternoon. The sky remained clear for the first part of the night when the thermometer dropped to 4.7c just after 2am but cloud cover meant that this rose to 9.7C at 08.00 with thin cloud reducing the strength of the sun.

Yesterday gave us 14.87 hours of strong sunshine, the highest total since 30th June 2015. The southerly breezes (high 19 mph) modified the maximum temperature to 16.7C, average for early May. Clear skies overnight produced another cool morning with a minimum of 1.3C but the strong sunshine from dawn meant that the thermometer had risen to 9.2C at 08.00 with low humidity of 73% at this time. UV levels this month are nudging into the ‘High’ category.
