Springfield's climate has few extremes and is characteristic of the north central region of the U.S. Rainfall is rather evenly distributed throughout the year. This, with moderate temperatures, helps to make the Mad River Valley a rich agricultural region. The daily maximum temperature varies from 37 degrees in January to a high of 88 degrees in July. Extreme temperatures are usually short in duration.
Each year's frost free period extends about 6 months. The last spring freeze is usually recorded in mid-April. The first fall frost is recorded in late October with some instances of late November recordings.
