Summer is the warmest season in the UK and on average, July is the warmest month and June is the sunniest while the rainfall totals throughout the UK in summer can be rather variable. The highest temperatures in summer tend to be seen around London and the southeast, with the coolest temperatures experienced throughout Scotland and Northern England.

The UK in summer can experience blocking anticyclones which can bring long spells of warm weather and create heatwave conditions.

The summer heatwave of 2022 was unprecedented and marked a milestone in UK climate history with 40°C being recorded for the first time in the UK and new national records set in Wales, Scotland and England.

What is a heatwave?

A heatwave is an extended period of hot weather relative to the expected conditions of the area at that time of year, which may be accompanied by high humidity. Find out more about how we define a heatwave.
