The year, day by day
The year in Winnsboro runs from a mild 37°F around January 13 to 94°F at the peak near August 4, and the normal low never reaches freezing on any date in the record.
When the heat sits
Normal highs reach 90°F from June 11 through September 13, covering 95 dates. The broader mild season, normal highs of 70°F or more, runs March 20 to November 10.
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 37°F around January 13.
Where the wet dates fall
The likeliest wet date is January 8, when 29% of years recorded at least a hundredth of an inch. The driest is September 29 at 16%. Summed across the calendar, that is about 88 wet dates a year.
The widest day
October 15 carries the biggest normal gap between afternoon and dawn, 26°F between the normal high and the normal low.

Where Winnsboro Stands Nationally
Summers here run among the most heat-heavy normals calendars in the country: on about 95 days a year the normal daily high itself reaches 90°F — a count fewer than one station in ten exceeds.
This is one of the wettest normals climates ranked: about 58 inches of precipitation in a normal year, a total fewer than one station in ten surpasses.
Winnsboro earns 2 nationally notable standings (outer quintiles) against 6,860 NOAA 1991–2020 normals stations; only those extremes render.

Winnsboro 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 28%, with neither reaching the 35% that would mark a distinct wet season. Winnsboro has no dry season to plan around, though it does carry a 35.9°F seasonal spread.
The gap between the wettest and driest month still matters: April averages 6.3" and September 3.6". 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 Winnsboro, it arrives in quantity
58.3" of precipitation falls across only about 88 wet days here, averaging 0.66 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 88 a year, 24% of all days
- Average depth per wet day
- 0.66 inches
- Most wet days
- January, about 9
- Fewest wet days
- September, about 5
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.
Snow reaches Winnsboro, but rarely amounts to much
The normals record 0.3 inches of snow a year here, most likely in February. That is a real but marginal amount: enough that snow is part of the local record, not enough to define the winter.
A figure in this range usually reflects a handful of events that melt quickly rather than a season of accumulation; about 0 days a year record any measurable snow at all.
NOAA 1991-2020 normals. An average across thirty years can smooth away a single heavy winter, so a small annual figure does not mean a significant snowfall is impossible.

Data-derived climate profile
How Winnsboro's climate pattern fits together
mixed demand · wet · mid swing
Water is prominent even though neither heating nor cooling wholly defines the record. Winnsboro averages 58.3 inches of precipitation a year. Recorded annual snowfall is negligible. 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 Winnsboro's middle-range seasonal profile. The measured spread is 35.9°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 Winnsboro's normal, at 2,154 and 2,587 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 251 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 Winnsboro'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 Winnsboro, the bands are descriptive ranges rather than an official NOAA classification or a forecast.
