Although we enjoyed some sunshine yesterday, the total hours were down again at 1.63. These reduced hours and brisk northerly wind flow meant a maximum of only 12.2C, which is a signifiant 4.4C below the average of May. However, during the brief strong sunshine the UV level rose fractionally again to 7.1, which nudged into the ‘Very High’ category. These temperatures are lower than the April average.
We have now experienced 8 successive dry days with the rainfall total of just 3.1mm when the May average is 60.5mm. Also relevant in this dry spell is that the first nine days of May have resulted in the equivalent rainfall total of 28mm evaporating into the atmosphere from ground sources and plant life.
Overnight the thermometer fell to -1.2C at 05.43 giving a sharp air frost, being the coldest night for a fortnight. This morning dawned with hazy sunshine due to a slight mist, then a narrow fog band drifting in front the east between 06.30 and 07.00, that quickly evaporated in the strengthening sunshine.
