The year, day by day

The year in Saint Leo runs from a mild 49°F around January 12 to 90°F at the peak near July 21, and the normal low never reaches freezing on any date in the record.

When the heat sits

Normal highs reach 90°F from July 10 through August 19, covering 41 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 49°F around January 12.

Where the wet dates fall

The likeliest wet date is August 1, when 57% of years recorded at least a hundredth of an inch. The driest is November 11 at 19%. Summed across the calendar, that is about 119 wet dates a year.

The widest day

May 1 carries the biggest normal gap between afternoon and dawn, 23°F between the normal high and the normal low.

Where Saint Leo Stands Nationally

The normal water year runs well above the national norm at roughly 54 inches.

Days and nights track unusually close together; the widest normal swing, about 23°F, is narrower than most stations record.

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

Saint Leo runs a summer-peaked wet season

46% of Saint Leo'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 8.3", on an unusually narrow 21.7°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 Saint Leo, it arrives in quantity

53.5" of precipitation falls across only about 118 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.

Days with measurable precipitation
about 118 a year, 32% of all days
Average depth per wet day
0.45 inches
Most wet days

Fewest wet days
November, 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.

Saint Leo'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 Saint Leo's climate pattern fits together

cooling led · wet · low swing

Warm-season load persists through a relatively even calendar in Saint Leo. Cooling totals 3,149 degree days, more than double the 619 heating measure, and the 21.7°F seasonal range is compact rather than sharply divided.

Warm-season demand is paired with a wet annual normal: 53.5 inches of precipitation at Saint Leo. Recorded annual snowfall is negligible. The month-by-month bars distinguish a concentrated wet season from moisture spread across the calendar.

Saint Leo's 21.7°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 72°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 Saint Leo. 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 Saint Leo'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 Saint Leo that means a descriptive range only — not an official NOAA classification and not a prediction for next summer.

Questions about Saint Leo's climate

How much rain does Saint Leo get?
Saint Leo receives 53.5 inches of precipitation. Based on NOAA 30-year climate normals (1991-2020).
How many days above 90°F does Saint Leo get?
Saint Leo averages about 114 days a year at or above 90°F, concentrated in August and the months either side of it. That is a count of days reaching the threshold, not a measure of how far above it they go.
How much energy does heating and cooling require in Saint Leo?
Saint Leo has 619 heating degree days and 3,149 cooling degree days annually, a cooling-dominated climate. Degree-day definitions: reading weather data.

Data Sources

Data source: NOAA U.S. Climate Normals v1.0.1 (1991-2020). All figures on this page are from Saint Leo's primary station: SAINT LEO (USC00087851). For informational purposes only.

Place identity: U.S. Census Bureau 2024 Gazetteer places. The conservative exact name-and-state crosswalk finds no Census place match, so PlainClimate treats this as a station-mapped location and does not claim it is a municipality. No exact Gazetteer row for Saint Leo; facility counts that depend on place identity are therefore an upper bound, not a municipal census.
