Climate chart - Brighton (England)
In Brighton, a coastal town south of London, in East Sussex county, the climate is oceanic, with quite cold, rainy winters and mild, relatively rainy summers.
However, the southern coast of England, where Brighton is located, has a mild and sunny microclimate compared to the rest of Great Britain.
Winter is not very cold, but the sky is often cloudy, the humidity is high and there are periods when the wind blows moderate or strong. The rains are frequent.
Snow is rare, but can occasionally occur. On the coldest nights of the year, the temperature generally drops to around -5 °C (23 °F), but can sometimes drop to lower values. In nearby Shoreham Airport, the temperature dropped to -9.7 °C (14.5 °F) in December 2010.
In summer, temperatures are generally mild or cool. It can also rain, albeit a little less often than in winter.
Due to its coastal location, Brighton is a little more sheltered from the heat waves that can sometimes affect the south east of England. However, hot periods cannot be ruled out, usually of short duration. The highest record is 33.4 °C (92.1 °F) and was set in July 2022.
The average temperature ranges between 5.5 °C (42 °F) in January and February to 17.2 °C (63 °F) in July and August. Here are the average temperatures.

Best Time
The best time to visit Brighton is the summer, from June to August, since it is the warmest of the year, although even in this season, it's better to bring a sweatshirt, a light jacket and an umbrella. The month of June is a bit cooler, so you may prefer July and August. September is a good month as well: it's a bit rainier than the summer months, but the temperatures are still pleasant, especially in the first part.
As previously mentioned, the sea is very cool even in summer, however, on sunny days, when the breeze is not too cool, you can sunbathe.
