The year, day by day
Summer here tops out rather than builds: the warmest normal high is 85°F around July 6, short of 90°F on every date, while 69 dates carry a normal low at or below freezing, the coldest 27°F near January 17.
The freezing stretch
The normal low stays at or below 32°F into February 21, then returns to freezing around December 15, covering 69 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 February 21, when 48% of years recorded at least a hundredth of an inch. The driest is September 15 at 27%. Summed across the calendar, that is about 148 wet dates a year.
The widest day
April 8 carries the biggest normal gap between afternoon and dawn, 22°F between the normal high and the normal low.

Where Jackson Stands Nationally
The normal water year runs well above the national norm at roughly 52 inches.
Days and nights track unusually close together; the widest normal swing, about 22°F, is narrower than most stations record.
Jackson earns 2 nationally notable standings (outer quintiles) against 6,860 NOAA 1991–2020 normals stations; only those extremes render.

Jackson spreads its precipitation across the year
Neither half of the year dominates here: June through August take 28% of the annual total and December through February 24%, 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 39.9°F seasonal spread.
The gap between the wettest and driest month still matters: June averages 5.3" and September 3.4". 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 Jackson, it arrives in quantity
51.9" of precipitation falls across only about 148 wet days here, averaging 0.35 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 148 a year, 41% of all days
- Average depth per wet day
- 0.35 inches
- Most wet days
- January, about 14
- Fewest wet days
- September, about 8
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.
Winter brings real snow to Jackson
Jackson averages 23.4 inches of snowfall a year, with January the snowiest month on the normals, spread across roughly 22 days that record measurable snow. That is depth accumulating on the ground, which is why it can exceed the annual precipitation figure: precipitation counts the liquid the snow melts down to, and fresh snow is mostly air.
- Annual snowfall: 23.4 inches of depth.
- Days recording measurable snow: about 22 a year.
- At a rough ten-to-one melt ratio, snow accounts for on the order of 5% of the year's precipitation.
NOAA 1991-2020 normals. The ten-to-one ratio is a convention, not a measurement: real ratios vary with temperature, so treat the share as an order of magnitude rather than an exact split.

Snow and freeze rhythm
When cold and snow define Jackson
heating led · wet · mid swing
Jackson's energy balance leans toward cold weather: 4,069 annual heating degree days against 1,236 for cooling. Its 39.9°F seasonal range still makes the monthly rows more useful than the annual average alone.
Jackson's frost-free season lasts about 209 days, a middle-length window whose endpoints matter more than the annual average. It describes freeze probability, not year-specific planting conditions.
-
1. Jackson coldest normal
