The year, day by day
Summer here tops out rather than builds: the warmest normal high is 89°F around July 23, short of 90°F on every date, while 105 dates carry a normal low at or below freezing, the coldest 20°F near January 18.
The freezing stretch
The normal low stays at or below 32°F into March 8, then returns to freezing around November 25, covering 105 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 42% of years recorded at least a hundredth of an inch. The driest is December 24 at 24%. Summed across the calendar, that is about 109 wet dates a year.
The widest day
October 6 carries the biggest normal gap between afternoon and dawn, 23°F between the normal high and the normal low.

Boonville spreads its precipitation across the year
Neither half of the year dominates here: June through August take 32% of the annual total and December through February 14%, with neither reaching the 35% that would mark a distinct wet season. Boonville has no dry season to plan around, though it does carry a wide 49.7°F gap between its warmest and coldest month.
The gap between the wettest and driest month still matters: May averages 5.0" and December 1.6". The three wettest months together take 34% 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 Boonville, it arrives in quantity
41.0" of precipitation falls across only about 109 wet days here, averaging 0.38 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 109 a year, 30% of all days
- Average depth per wet day
- 0.38 inches
- Most wet days
- May, about 13
- Fewest wet days
- December, 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.
Winter brings real snow to Boonville
Boonville averages 13.3 inches of snowfall a year, with January the snowiest month on the normals, spread across roughly 7 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: 13.3 inches of depth.
- Days recording measurable snow: about 7 a year.
- At a rough ten-to-one melt ratio, snow accounts for on the order of 3% 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.

heating led · moderate · mid swing
Boonville's energy balance leans toward cold weather: 4,866 annual heating degree days against 1,497 for cooling. Its 49.7°F seasonal range still makes the monthly rows more useful than the annual average alone.
Boonville's frost-free season lasts about 207 days, a middle-length window whose endpoints matter more than the annual average. It describes freeze probability, not year-specific planting conditions.
