Today we mark the summer solstice, the longest day of the year, signalling the start of astronomical summer.

A solstice occurs when one of Earth’s pole reaches its maximum tilt towards the Sun. For those of us in the Northern Hemisphere, it will be the longest of the year, but for those in the Southern Hemisphere, it’s the opposite.

On the summer solstice, the sun travels its longest path after rising, reaching its northernmost point. The precise time of the summer solstice on June 21st is at 03:42 am.

The summer solstice is over 9 hours longer in daylight length than the winter solstice! Make sure you make the most of the additional daylight!

Hottest solstice ever?

In the midst of a heatwave, temperatures are expected to reach up to 33°C. The hottest solstice on record was in 2017 with a high of 34.5°C.

The sun is also at its strongest on the solstice, which means you need to take extra precaution in the sun, especially as the UV Index is forecast to reach high levels across some parts of England and Wales.

While meteorological summer began on June 1st, and will last until August 31st, astronomical summer relies on the tilt of the Earth and its rotational axis, which will end on September 22nd, when the autumn equinox then occurs.

The image shows an intense tropical cyclone over the western Pacific, east of Taiwan and the Philippines. The centre of the system is depicted as a light purple and white vortex with a clearly visible eye, surrounded by a ring of red and orange areas indicating the strongest wind speeds. A white arrow marks the typhoon’s predicted track towards the north-west, in the direction of Taiwan. To the west of the storm lie the Philippines, with the cities of Manila and Cebu; to the north of these lies Taiwan, with Taipei. Further west, the Chinese coast, including Hong Kong, and parts of Vietnam can be seen. The coloured wind map shows predominantly green areas outside the storm’s core, indicating significantly weaker winds. White streamlines illustrate the typhoon’s anti-clockwise circulation in the Northern Hemisphere. The highest wind speeds are concentrated around the eye of the cyclone.
