Plentiful Rainfall Offsets Moderate Heat
Annual precipitation of 46.4 inches is higher than the state average, providing an excellent natural water supply. The 13 extreme heat days and 3,214 growing degree days suggest a robust season with steady grass production. This extra rain helps lawns recover quickly from the occasional 90°F summer afternoon.
