The year, day by day
The year in Miami runs from a mild 35°F around December 17 to 100°F at the peak near July 4, and the normal low never reaches freezing on any date in the record.
When the heat sits
Normal highs reach 90°F from May 24 through September 28, covering 128 dates. The broader mild season, normal highs of 70°F or more, runs March 10 to November 19.
This counts calendar dates whose 1991–2020 normal high reaches 90°F. It is a smaller number than the 90°F+ day counts in the monthly table above, which measure how often the threshold was actually crossed in a typical year. A date can average 88°F and still exceed 90°F in half of all years.
No freezing date
Not one calendar date in the 1991–2020 record carries a normal low at or below 32°F. The coldest normal low of the year is 35°F around December 17.
Where the wet dates fall
The likeliest wet date is August 10, when 28% of years recorded at least a hundredth of an inch. The driest is May 31 at 5%. Summed across the calendar, that is about 51 wet dates a year.
The widest day
April 1 carries the biggest normal gap between afternoon and dawn, 30°F between the normal high and the normal low.

Where Miami Stands Nationally
Summers here run among the most heat-heavy normals calendars in the country: on about 128 days a year the normal daily high itself reaches 90°F — a count fewer than one station in ten exceeds.
Miami earns one nationally notable standing (outer quintile) against 6,860 NOAA 1991–2020 normals stations, middle-of-the-pack metrics stay silent here.

Miami's wet season runs through the cold months
December, January and February carry 37% of the year's precipitation here, while June through August contribute 29%. That is the cool-season-dominant pattern of the West Coast and the higher inland West, where storm tracks swing south in winter and summer turns dry; the thermometer meanwhile shows a 37.7°F seasonal spread.
- Wettest month
- August, 2.6"
- Driest month
- June, 0.3"
- Wettest three months
- August, January, July (41% of the year)
Shares are computed from this station's own 1991-2020 monthly precipitation normals. A cool-season label means the December-February share reaches 35%. Where snow falls, the monthly figures above report liquid-equivalent precipitation, so a wet winter month is not necessarily a rainy one.
How Miami's precipitation splits across the calendar
About 51 days a year record measurable precipitation here, carrying 17.2" between them, or roughly 0.34 inches on a typical wet day. That sits in the middle band: neither the many-light-days pattern of the Pacific Northwest and the Great Lakes, nor the few-heavy-events pattern of the Gulf and the desert Southwest.
A wet day is one recording at least 0.01 inches. These are 1991-2020 normals: they describe an average year and say nothing about the heaviest single storm on record.
Miami's record shows no measurable snowfall
This station measured snowfall across the 1991-2020 period and recorded none: the annual normal is 0.0 inches. That is a measured zero rather than missing data, which is a meaningful distinction here , most stations in the database simply do not report snow at all, and those pages say nothing about it.
A thirty-year normal of zero describes the typical year at this station. It is not a claim that snow has never fallen in the area.

Data-derived climate profile
How Miami's climate pattern fits together
mixed demand · dry · mid swing
Local precipitation is sparse in this otherwise mixed profile. The station reports 17.2 inches annually, within PlainClimate's dry band. Recorded annual snowfall is negligible. The monthly distribution matters because the total alone does not reveal the timing.
July and December mark the typical warm and cold ends of the calendar in Miami's middle-range seasonal profile. The measured spread is 37.7°F. The annual average is 67°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Heating and cooling both register in Miami's normal, at 2,053 and 2,758 degree days respectively. Neither total exceeds the other by more than two to one, so the record is better read as a mixed-demand calendar than as heating-led or cooling-led.
Miami has a long frost-free window of roughly 280 days, but the dry annual profile is a separate constraint. Growing-season length says when freezes are unlikely, not whether rainfall is sufficient.
These labels group NOAA 1991-2020 normals from Miami's primary station, where heating and cooling demand are close enough that neither season sets the character on its own. On a balanced station like Miami, the bands are descriptive ranges rather than an official NOAA classification or a forecast.
