The year, day by day
The year in Monroe Rgnl runs from a mild 36°F around January 13 to 94°F at the peak near August 1, and the normal low never reaches freezing on any date in the record.
When the heat sits
Normal highs reach 90°F from June 10 through September 11, covering 94 dates. The broader mild season, normal highs of 70°F or more, runs March 19 to November 7.
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 36°F around January 13.
Where the wet dates fall
The likeliest wet date is February 21, when 34% of years recorded at least a hundredth of an inch. The driest is September 28 at 22%. Summed across the calendar, that is about 106 wet dates a year.
The widest day
October 17 carries the biggest normal gap between afternoon and dawn, 25°F between the normal high and the normal low.

Where Monroe Rgnl Stands Nationally
Summers here run among the most heat-heavy normals calendars in the country: on about 94 days a year the normal daily high itself reaches 90°F — a count fewer than one station in ten exceeds.
The normal water year runs well above the national norm at roughly 55 inches.
Monroe Rgnl earns 2 nationally notable standings (outer quintiles) against 6,860 NOAA 1991–2020 normals stations; only those extremes render.

Monroe Rgnl spreads its precipitation across the year
Neither half of the year dominates here: June through August take 22% of the annual total and December through February 27%, with neither reaching the 35% that would mark a distinct wet season. Monroe Rgnl has no dry season to plan around, though it does carry a 36°F seasonal spread.
The gap between the wettest and driest month still matters: April averages 5.8" and September 3.5". The three wettest months together take 30% of the year, against the 25% a perfectly flat distribution would give them.
Shares are computed from this station's own 1991-2020 monthly precipitation normals. "Spread across the year" means neither the June-August nor the December-February share reaches 35%; it describes an average year, not the variability of any single one.
When it rains in Monroe Rgnl, it arrives in quantity
55.1" of precipitation falls across only about 106 wet days here, averaging 0.52 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 106 a year, 29% of all days
- Average depth per wet day
- 0.52 inches

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 Monroe Rgnl's climate pattern fits together
mixed demand · wet · mid swing
Water is prominent even though neither heating nor cooling wholly defines the record. Monroe Rgnl averages 55.1 inches of precipitation a year. Snowfall is not added to the interpretation because its annual value is missing. The monthly table supplies the seasonal distribution hidden by that annual total.
July and January mark the typical warm and cold ends of the calendar in Monroe Rgnl's middle-range seasonal profile. The measured spread is 36.0°F. The annual average is 66°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Heating and cooling both register in Monroe Rgnl's normal, at 2,213 and 2,495 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.
The frost-free window extends for about 252 days. That is a long calendar measure, but it is not a forecast and does not combine heat, rainfall, soil, or local elevation into a planting recommendation.
These labels group NOAA 1991-2020 normals from Monroe Rgnl'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 Monroe Rgnl, the bands are descriptive ranges rather than an official NOAA classification or a forecast.

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 Monroe Rgnl; facility counts that depend on place identity are therefore an upper bound, not a municipal census.
