Climate chart - Norwich
The climate of Norwich is oceanic, with quite cold, rainy winters and mild, relatively rainy summers.
The city is located in the east of England, in Norfolk, about 30 km (18 mi) from the North Sea coast.
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.
Due to its location exposed to the north wind, the county of Norfolk is prone to rain or snow showers during cold air irruptions from the north.
On the coldest nights of the year, the temperature generally drops to around -6/-7 °C (19/21 °F), but can sometimes drop to lower values. In Coltishall, located 10 km (6 mi) north-east of Norwich, the temperature reached -15 °C (5 °F) in January 1979.
In summer, temperatures are generally mild or cool. It can also rain, albeit a little less often than in winter. Sometimes, fog can come from the sea at night and in the early morning.
Due to its northerly location and closer to the sea, Norwich is less exposed to the summer heatwaves that can sometimes affect the south-east of England, particularly the London area and up to Cambridge. However, hot periods cannot be ruled out, usually of short duration. The temperature reached 37 °C (98.5 °F) in July 2022 and 35 °C (95 °F) in August 2020.
On the coast (see Great Yarmouth, Lowestoft), the sea temperature ranges between 7 °C (45 °F) and 17 °C (63 °F). So, it never becomes warm for swimming. Here are the average sea temperatures.
