South East England combines the highest average daytime temperatures found in the British Isles with the highest sunshine averages on the British mainland. There are between 25 and 30 inches (635-760 mm) of rainfall; and there can be high variation of temperature between day and night.

The climate of the coastal districts is strongly influenced by the sea, which because of its tendency to warm up slower than land, can result in cooler temperatures than inland in the summer. In the autumn months, the coast sometimes has higher temperatures. Rainfall during the summer months is mainly from thunderstorms and thundery showers; from January to March the heavier rainfall is due to south-westerly frontal systems. The coast has consistently more sunshine than the inland areas: sea breezes, blowing off the sea, clear any cloud from the coast.
