Nampa Weather in September
United States · early fall in Northern Hemisphere
Nampa is Idaho's third-largest city and a significant agricultural hub in the Treasure Valley. Lake Lowell (Deer Flat National Wildlife Refuge) provides a significant water body nearby that creates localized weather patterns. The city is more agricultural than Boise with some remaining evapotranspiration cooling from surrounding farmland.
Excellent shoulder season — warm with fewer tourists in many destinations.
