Bristol weather in numbers
measured normals and 10 years of recorded weatherBristol swings 18°C across the year, from 20°C highs in August to 2°C lows in January, and October is usually the wettest month in a year that brings about 887 mm of precipitation. Over 10 years of recorded weather it averages 10 days a year at 25°C or above, 1 of them at 30°C or above, 25 frost nights, and rain on 158 days.
Day counts are from the ERA5 reanalysis for Bristol’s grid square, 2016 to 2025, counted the same way for every city so the numbers compare. A reanalysis square is an area, not a weather station, so it is good for counting days and not for a single day’s record.

Source: NASA POWER daily data from the MERRA-2 reanalysis, 1995-2024. Each value describes a grid square of about 50 km around Bristol, not a weather station, and a square that takes in sea or a large lake runs milder than the city itself. That is why this section shows change against the square's own 30-year average rather than counts you could compare with a local station. Rain and snow are left out because their long-term record in this dataset is not consistent over time. "Within the normal year-to-year swing" means the change is smaller than the usual differences between single years.
Which forecast is most accurate in Bristol?
CheckWeather Score, graded against the weather that actually happened
The CheckWeather Score blends temperature, wind and rain accuracy, each measured against ERA5 (the recorded weather) over the last 30 days across 1950 cities. Lower error means a higher score. See which forecast model is most accurate in United Kingdom, how we measure forecast accuracy, or which model each weather app uses.
Bottom line: over the last 30 days the European model has been the most accurate forecast for Bristol, scoring 92/100 on our CheckWeather Score, ahead of the American at 81. See the full UK accuracy scoreboard for exactly how every model is tested.

Where the models disagree
temperature and rain, judged separatelyThe models often agree on temperature and still split on rain, and rain is usually what decides whether a plan survives. A wide rain range means the shower is genuinely uncertain, not that the forecast is wrong.
