measured normals and 10 years of recorded weatherSaint-Eustache swings 41°C across the year, from 26°C highs in July to -15°C lows in February, and June is usually the wettest month in a year that brings about 1049 mm of precipitation. Over 10 years of recorded weather it averages 62 days a year at 25°C or above, 9 of them at 30°C or above, 147 frost nights, and rain on 142 days.
Day counts are from the ERA5 reanalysis for Saint-Eustache’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.
