You might not think of the UK as the best place to be for some sun-seeking, but you’ll be surprised at just how hot parts of Britain can get. Sure, average annual temperatures hover around a daily high of 14 degrees Celsius (56 degrees Fahrenheit) and a low of 6 °C (43 °F). But the hottest places in the UK can rival balmy European destinations. The hottest day ever recorded in the UK was July 25, 2019, when the mercury hit 38.7C in Cambridge. This heatwave was due to a weather pattern that drew hot air from Africa northwards across a broad patch of Europe.

In fact, there has been an increase in regional temperatures across the UK since the 1960s.

Generally, the South West part of England has the warmest weather, with parts such as Cornwall enjoying a special sub-tropical climate. Northern parts of England and Scotland typically experience the coldest weather and harsh winters. As for the UK’s reputation for rain, rain. and more rain? London on average has just over 106 rainy days of the year, lower than Miami or New York City, which both come in higher at 135 and 122 days respectfully.

Planning a staycation this year and hoping for some sun? Add these warm places in the UK to your vacation hotlist.
