Bolingbrook weather in numbers
measured normals and 10 years of recorded weatherBolingbrook swings 64°F across the year, from 82°F highs in July to 18°F lows in January, and June is usually the wettest month in a year that brings about 41 in of precipitation. Over 10 years of recorded weather it averages 97 days a year at 77°F or above, 27 of them at 86°F or above, 115 frost nights, and rain on 131 days.
Day counts are from the ERA5 reanalysis for Bolingbrook’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.
