In this part of the UK (on a peninusla that juts 8 miles (12Km) into the sea, we get mild winters (rarely below freezing for long, and then not by much) and moderate summers (typically up to about 80-85F).
But as with all of the UK, things can get more extreme at almost any time of the year. Hottest ever was about 95F, and coldest ever was about -20F, in my experience. But thse extremes are very rare.
Most of the time, wet, windy and mild.
