Spring Valley weather in numbers
measured normals and 10 years of recorded weatherSpring Valley swings 66°F across the year, from 103°F highs in July to 37°F lows in December, and February is usually the wettest month in a year that brings about 7 in of precipitation. Over 10 years of recorded weather it averages 200 days a year at 77°F or above, 154 of them at 86°F or above, 7 frost nights, and rain on 23 days.
Day counts are from the ERA5 reanalysis for Spring Valley’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.
