The year, day by day

The year in West Palm Beach runs from a mild 58°F around January 14 to 90°F at the peak near July 24, and the normal low never reaches freezing on any date in the record.

When the heat sits

Normal highs reach 90°F from July 14 through August 16, covering 34 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 58°F around January 14.

Where the wet dates fall

The likeliest wet date is August 26, when 58% of years recorded at least a hundredth of an inch. The driest is February 18 at 24%. Summed across the calendar, that is about 138 wet dates a year.

The widest day

January 22 carries the biggest normal gap between afternoon and dawn, 17°F between the normal high and the normal low.

Where West Palm Beach Stands Nationally

This is one of the wettest normals climates ranked: about 62 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 17°F.

West Palm Beach earns 2 nationally notable standings (outer quintiles) against 6,860 NOAA 1991–2020 normals stations; only those extremes render.

West Palm Beach runs a summer-peaked wet season

37% of West Palm Beach'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 August at 8.7", on an unusually narrow 16.9°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.

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 West Palm Beach, it arrives in quantity

61.7" of precipitation falls across only about 137 wet days here, averaging 0.45 inches each. Fewer days carry more water: the year's total is delivered in comparatively heavy events rather than persistent damp.

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.

Data-derived climate profile

How West Palm Beach's climate pattern fits together

cooling led · wet · low swing

Warm-season load persists through a relatively even calendar in West Palm Beach. Cooling totals 4,166 degree days, more than double the 202 heating measure, and the 16.9°F seasonal range is compact rather than sharply divided.

Warm-season demand is paired with a wet annual normal: 61.8 inches of precipitation at West Palm Beach. Snowfall is not added to the interpretation because its annual value is missing. The month-by-month bars distinguish a concentrated wet season from moisture spread across the calendar.

West Palm Beach's 16.9°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 76°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 West Palm Beach. 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 West Palm Beach'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 West Palm Beach that means a descriptive range only — not an official NOAA classification and not a prediction for next summer.

Questions about West Palm Beach's climate

How much rain does West Palm Beach get?
