What is summer?

Beginning in June, summer is the warmest season in the UK due to the northern hemisphere being tilted towards the sun.

When is summer?

Summer in the meteorological calendar covers the duration of June, July and August, or by the astronomical calendar it begins around 21 June on a day referred to as the summer solstice.

The summer solstice marks the point when the sun reaches its highest point in the sky. This is the longest day of the year, after this the days get shorter until the winter solstice which occurs around 22 December. At the same time the Northern Hemisphere experiences summer solstice, the Southern Hemisphere has a winter solstice.

What is the weather like in summer?

On average in the UK, 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 south-east 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.
