Birmingham climate
Birmingham’s warm season is balanced by humidity and a real winter
Birmingham’s published climate rows show a 90°F average summer high, 54 days above 90°F, a 37°F average winter low, and 42 days below freezing. Humidity is 77 percent, six months are comfortable, solar exposure is 1,655 peak sun hours per year, and March through June plus September and October are best while July, August, and January are toughest.
Air quality is labeled Excellent, allergy levels are Poor, long term fine particle pollution is 7.5 micrograms per cubic meter for the 2021 to 2025 modeled average, climate heat risk is Moderate, drought risk is Low, and weather volatility is Moderate. A comfortable Birmingham home needs cooling, shade, ventilation, winter heating, allergy alternatives, and storm preparation.

Plan Birmingham’s heat, humidity, and winter together
Visit in winter and summer
Notice cooling, heating, windows, humidity, allergies, shade, lighting, parking, power, storms, and how the home feels after a cold or warm day.
Price home comfort
Review cooling, heating, insulation, windows, utilities in rent, insurance, maintenance, power, ventilation, shade, drainage, and storm preparation.
Choose indoor alternatives
Identify Railroad Park, civil rights history, arts and culture, recreation, parks, care options, and nearby choices for Poor allergy days, heat, rain, storms, or cold.
Keep both heat fields visible
Use the Moderate climate heat row and separate High safety hazard heat row alongside the 90°F summer high, 37°F winter low, 77 percent humidity, and six comfortable months.
