Brecon weather in numbers
measured normals and 10 years of recorded weatherBrecon swings 17°C across the year, from 19°C highs in August to 2°C lows in January, and December is usually the wettest month in a year that brings about 1319 mm of precipitation. Over 10 years of recorded weather it averages 6 days a year at 25°C or above, 31 frost nights, and rain on 176 days.
Day counts are from the ERA5 reanalysis for Brecon’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.
