Springfield climate
Springfield’s comfortable summer is framed by a long freezing season
Springfield’s climate rows show an 84°F average summer high, 11 days above 90°F, a 22°F average winter low, and 118 days below freezing. Humidity is 76 percent and five months are comfortable, with May through September listed as best and February, January, and December as toughest.
Springfield’s climate ledger labels air quality Excellent and allergy levels Poor. Long term fine particle pollution is 5.9 micrograms per cubic meter for the 2021 to 2025 modeled average, climate heat risk is Low, drought risk is High, and weather volatility is Moderate. The year therefore asks more from heating, insulation, moisture control, indoor life, and allergy planning than from summer cooling alone.

Price home comfort
Price the Springfield home’s heating, cooling, insulation, windows, utilities in rent, insurance, maintenance, power, ventilation, drainage, and storm preparation.
Choose indoor alternatives
Identify downtown museums, arts, libraries, recreation, community spaces, and nearby choices for Poor allergy days, cold, storms, or a short outdoor window.
Keep the two heat fields visible
Use the Low climate heat row and separate Moderate safety hazard heat row alongside the 84°F summer high, 22°F winter low, 76 percent humidity, and five comfortable months.
