measured normals and 10 years of recorded weatherSouth Granville swings 21°C across the year, from 22°C highs in July to 1°C lows in February, and November is usually the wettest month in a year that brings about 2081 mm of precipitation. Over 10 years of recorded weather it averages 16 days a year at 25°C or above, 1 of them at 30°C or above, 33 frost nights, and rain on 162 days.
Day counts are from the ERA5 reanalysis for South Granville’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.
