measured normals and 10 years of recorded weatherSurrey swings 23°C across the year, from 24°C highs in August to 1°C lows in January, and November is usually the wettest month in a year that brings about 1606 mm of precipitation. Over 10 years of recorded weather it averages 27 days a year at 25°C or above, 3 of them at 30°C or above, 50 frost nights, and rain on 163 days.
Day counts are from the ERA5 reanalysis for Surrey’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.

Which forecast is most accurate in Surrey?
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 1320 cities. Lower error means a higher score. See which forecast model is most accurate in Canada, 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 Surrey, scoring 90/100 on our CheckWeather Score, ahead of the American at 84. See the full CA 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.
