What’s the weather like in London?
The Brits are famous for talking endlessly about the weather – that’s because it changes so often and can be quite unpredictable. In general however, it is best to expect the weather in London to be dry and cool, and will need at least a light jacket for the majority of the year when you are touring the city.
The best time of the year to visit London is between April and August. This is when the weather is warmest, it is more likely to be sunny and dry and there are more hours of sunlight every day. Between September and March, we would definitely recommend bringing an umbrella with you when you are walking around the city. During this time, you should expect it to be cold and you will need a bigger coat and a scarf.
London is one of the warmest regions in the UK because it is in the south east of the British Isles: London avoids the coldest and wettest parts of the weather, which are blown directly at the UK’s western coastline from the Atlantic Ocean. The seasons in London (and in the rest of the UK) run roughly like this:
In the spring, London’s average temperature is 14°C (57°F) and the average rainfall is 40-60mm per month.
In the summer, London’s average temperature is 21°C (70°F) and the average rainfall is 40-60mm per month.
In the autumn, London’s average temperature is 15°C (60°F) and the average rainfall is 60-80mm per month.
In the winter, London’s average temperature is 8°C (46°F) and the average rainfall is 60-80mm per month.
Despite what you might think, snow does not fall in London very often at all. It’s most likely to snow in London between December and March, but even when it does snow, in Central London the snow melts very quickly and just makes the city streets slippery and wet. If you’re in London and it does snow, we recommend going to Primrose Hill or Greenwich Park to enjoy it properly.
