Traveller notes on Bristol in December
Other months in Bristol
The UK forum's consistent line on early July: expect roughly 17°C on average with a real chance of rain, and treat any specific forecast as unreliable more than a few days out. Regulars across the south-west give the same standing advice for a trip to Bristol as anywhere else in Britain in summer — pack for both sun and rain, because a single day can bring either.
