Summer

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.

It's the most thundery time of the year

More thunderstorms occur during the summer than at any other time of the year.

The warmth of summer often provides the perfect conditions of rising air and moisture required for the creation of thunderstorms.

They are most likely to occur in the south east of England.

 Crickets get chirpy

Next time you hear the sound of crickets chirping on a balmy summer evening, why not try this simple trick to find out the temperature.

The frequency of a cricket's chirps is consistent with air temperature so you simply need to count how many chirps there are over 25 seconds then divide by 3 and add 4 to tell you the temperature in Celsius.

Snow in June

On 2 June 1975 snow showers forced the abandonment of several cricket matches across the country.

The coldest temperature ever recorded in summer in the UK is -5.6 C recorded on the 9 June 1955 in Dalwhinnie and again on the 1 and 3 June 1962 in Santon Downham in Norfolk.

 Top temperatures

The warmest ever summer in the UK was in 2006 when daytime temperatures averaged 15.8 °C.

The hottest temperature ever recorded in the UK was on 10 August 2003 when Faversham in Kent recorded a sweltering 38.5 °C

The longest day of the year is in summer

The The Equinox and Solstice marks the point when the sun reaches its highest point in the sky. This is the longest day of the year and after this point the days slowly begin to 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 marking the shortest day of the year.
