The year, day by day
Jackson works both ends of the calendar. Normal highs climb to 90°F by July 22 and hold at or above 90°F on 34 dates, then normal lows drop to freezing or below on 100 dates, bottoming at 23°F around January 20.
When the heat sits
Normal highs reach 90°F from July 5 through August 7, covering 34 dates. The broader mild season, normal highs of 70°F or more, runs April 19 to October 16.
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.
The freezing stretch
The normal low stays at or below 32°F into March 5, then returns to freezing around November 27, covering 100 dates in all.
Derived from the normal daily minimum. This is a different measure from the 50%-probability frost dates shown elsewhere on this page, which come from NOAA’s frost product.
Where the wet dates fall
The likeliest wet date is May 1, when 39% of years recorded at least a hundredth of an inch. The driest is September 13 at 22%. Summed across the calendar, that is about 111 wet dates a year.
The widest day
October 2 carries the biggest normal gap between afternoon and dawn, 24°F between the normal high and the normal low.

Jackson spreads its precipitation across the year
Neither half of the year dominates here: June through August take 24% of the annual total and December through February 21%, with neither reaching the 35% that would mark a distinct wet season. Jackson has no dry season to plan around, though it does carry a wide 47.2°F gap between its warmest and coldest month.
The gap between the wettest and driest month still matters: May averages 5.5" and January 3.3". The three wettest months together take 32% 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 Jackson, it arrives in quantity
50.5" of precipitation falls across only about 111 wet days here, averaging 0.46 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 111 a year, 30% of all days
- Average depth per wet day
- 0.46 inches
- Most wet days
- May, about 12
- Fewest wet days
- September, about 7
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 Jackson, but rarely amounts to much
The normals record 7.5 inches of snow a year here, most likely in December. 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 3 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 Jackson's climate pattern fits together
heating led · wet · mid swing
Jackson's energy balance leans toward cold weather: 4,499 annual heating degree days against 1,592 for cooling. Its 47.2°F seasonal range still makes the monthly rows more useful than the annual average alone.
Jackson's frost-free season lasts about 205 days, a middle-length window whose endpoints matter more than the annual average. It describes freeze probability, not year-specific planting conditions.
July and January mark the typical warm and cold ends of the calendar in Jackson's middle-range seasonal profile. The measured spread is 47.2°F. The annual average is 57°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Alongside its heating load, Jackson carries 50.5 inches of precipitation in a normal year, inside PlainClimate's wet range. Annual snowfall totals 7.5 inches. That distinction matters because a wet annual total can arrive as rain, snow, or a mixture at different times.
These labels group NOAA 1991-2020 normals from Jackson's primary station, so the winter figures are a thirty-year average and not a floor: a single hard season can run well below them. Treat each band as a descriptive range for Jackson, not an official NOAA class or a year-ahead forecast.
