Miami climate
Miami's climate is warm all year, but not gentle all year
Miami's average summer high is 86°F, with about one day above 90°F, while the average winter low is 71°F and there are no days below freezing. Five months are listed as comfortable, with January through March and November through December among the best months. June, August, and September are listed as the toughest months.
Humidity is 76 percent, allergies are marked poor, and weather volatility is shown at four of five. The long term fine particle figure is a modeled 5.4 micrograms per cubic meter average for 2021 to 2025, not a current street reading. Shade, air conditioning, mold prevention, storm timing, and insurance are part of the year round home question.

Miami in everyday life
Could Miami work for you?
What may work well
- Average winter lows around 71°F and no days below freezing support outdoor time through much of the cooler season.
- January through March and November through December are listed among the best months for visitors, parks, and errands.
- A warm year gives households many ways to use waterfront parks, museums, and outdoor services.
- The modeled long term fine particle figure is 5.4 micrograms per cubic meter for 2021 to 2025.
What to think about
- Humidity, heavy rain, storms, allergies, and the hottest months can narrow outdoor plans.
- Air conditioning, shade, ventilation, mold prevention, roof condition, and insurance affect the indoor year.
- The modeled air figure and other climate summaries cannot describe one home's comfort or exposure.
- A warm winter does not remove the need for a wet season route and a household plan for power interruptions.
Compare Miami's home through the whole year
Visit during the wet season
Spend time in June through September when possible, walking at different hours and noticing rain, humidity, shade, cooling, traffic, and evening comfort.
Price cooling and insurance
Ask about air conditioning, utilities, windows, roof, drainage, mold prevention, storm maintenance, flood exposure, and insurance.
Plan outdoor hours
Use the cooler months and earlier parts of hot days for parks, errands, visitors, and longer outings, while keeping shade and shorter plans available.
Keep indoor and care alternatives
Choose indoor options for heat, allergies, rain, and storms, and make sure the care route remains workable when outdoor conditions change.

What does Miami's air quality figure mean?
The long term fine particle figure is a modeled 5.4 micrograms per cubic meter average for 2021 to 2025, with air quality listed at 4.7 of 5. It is a planning baseline, not a current street reading or a guarantee about personal exposure.
Miami may suit a retiree who wants warm winters and outdoor options across much of the year, provided the home handles humidity, rain, storms, cooling, and allergies. Visit during the wetter months, compare the indoor experience, then use Save, Compare, or Find my fit.
