measured normals and 10 years of recorded weatherMission swings 25°C across the year, from 26°C highs in July to 1°C lows in January, and December is usually the wettest month in a year that brings about 1883 mm of precipitation. Over 10 years of recorded weather it averages 46 days a year at 25°C or above, 14 of them at 30°C or above, 45 frost nights, and rain on 178 days.
Day counts are from the ERA5 reanalysis for Mission’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.

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.
