The year, day by day
The year in Miami runs from a mild 61°F around January 14 to 91°F at the peak near July 27, and the normal low never reaches freezing on any date in the record.
When the heat sits
Normal highs reach 90°F from June 28 through August 31, covering 65 dates. The broader mild season, normal highs of 70°F or more, runs January 1 to December 31.
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 61°F around January 14.
Where the wet dates fall
The likeliest wet date is August 21, when 62% of years recorded at least a hundredth of an inch. The driest is March 2 at 21%. Summed across the calendar, that is about 141 wet dates a year.
The widest day
January 23 carries the biggest normal gap between afternoon and dawn, 15°F between the normal high and the normal low.

Any date's 1991–2020 normal for Miami.
Where Miami Stands Nationally
This is one of the wettest normals climates ranked: about 67 inches of precipitation in a normal year, a total fewer than one station in ten surpasses.
Among the steadiest day-night climates ranked: even the widest normal daily swing holds to roughly 15°F.
Miami earns 2 nationally notable standings (outer quintiles) against 6,860 NOAA 1991–2020 normals stations; only those extremes render.

Miami runs a summer-peaked wet season
41% of Miami's yearly precipitation falls in June, July and August alone, against the 25% an evenly spread year would give those three months. The wettest month is June at 10.5", on an unusually narrow 15.6°F seasonal spread. Warm-season convection and, across the Southwest, the North American monsoon produce this shape: rain arrives in short heavy bursts during the hottest part of the year rather than as long cool-season soaking.
- Wettest three months: June, September, August, taking 45% of the annual total between them.
- Driest month: January at 1.8".
- Winter share: 10% falls in December, January and February.
Shares are computed from this station's own 1991-2020 monthly precipitation normals. A summer-peaked label means the June-August share reaches 35%; it describes timing across an average year, not any single season, and says nothing about how heavy an individual storm can be.
When it rains in Miami, it arrives in quantity
67.4" of precipitation falls across only about 141 wet days here, averaging 0.48 inches each. Fewer days carry more water: the year's total is delivered in comparatively heavy events rather than persistent damp.
- Days with measurable precipitation
- about 141 a year, 39% of all days
- Average depth per wet day
- 0.48 inches
- Most wet days
- August, about 19
- Fewest wet days
- March, about 6
A wet day is one recording at least 0.01 inches. These are 1991-2020 normals: they describe an average year, and a per-day average is not a forecast of any individual storm.
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
cooling led · wet · low swing
Warm-season load persists through a relatively even calendar in Miami. Cooling totals 4,656 degree days, more than double the 104 heating measure, and the 15.6°F seasonal range is compact rather than sharply divided.
Warm-season demand is paired with a wet annual normal: 67.4 inches of precipitation at Miami. Recorded annual snowfall is negligible. The month-by-month bars distinguish a concentrated wet season from moisture spread across the calendar.
Miami's 15.6°F seasonal spread is compact even though precipitation is abundant. August and January mark the typical warm and cold ends of the calendar. The annual average is 77°F. Temperature is relatively steady; the monthly rows show how rain and snow observations vary across the calendar.
A frost-free growing-season length is not available for Miami. That missing field is kept separate from the observed temperature and precipitation record rather than filled from a regional estimate.
These labels group NOAA 1991-2020 normals from Miami's primary station, so the summer figures are a thirty-year average rather than a ceiling: individual years have run hotter and will again. For Miami that means a descriptive range only — not an official NOAA classification and not a prediction for next summer.
