Between the 5th and 13th a mere 0.2 millimetres (0.1 ins.) of rain fell, and although 2.8 millimetres (0.11 ins.) of rain were measured on the 15th, the first half of May yielded just 9 millimetres (0.35 ins.) of rain.

Wind
Pressure was higher than average across southern Britain, but with the centres usually positioned to the south of the country, it meant winds were predominantly from between southwest and northwest, with breezes from these quadrants accounting for more than two thirds of the daily readings. Although there were no particularly strong winds, sea breeze enhancement gave several cool and blustery afternoons. At Shoreham Airport, southwesterly winds gusted to 34 knots (39 mph) late in the afternoon on the 11th, and gusts of 33 knots (38 mph) occurred on the afternoon of the 25th. Although no further gusts above 30 knots (34 mph) occurred, several further afternoons in May had southwesterly gusts between 25 and 30 knots (29-33 mph).
