When is the longest day, when does summer start and what is the summer solstice?

The summer solstice sunrise marks the longest day of the year in the Northern Hemisphere.

But when exactly is it and when does summer then start?

Summer solstice occurs on 21 June every year, when the sun is directly above the Tropic of Cancer.

The winter solstice occurs every 21 December, when the sun is directly above the Tropic of Capricorn.

You can expect the sun to rise in the UK on Thursday 21 June at 4:43 am, so make sure you have those curtains...
