The year, day by day
Summer here tops out rather than builds: the warmest normal high is 75°F around July 17, short of 90°F on every date, while 174 dates carry a normal low at or below freezing, the coldest 7°F near January 26.
The freezing stretch
The normal low stays at or below 32°F into April 19, then returns to freezing around October 29, covering 174 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 January 4, when 64% of years recorded at least a hundredth of an inch. The driest is August 31 at 40%. Summed across the calendar, that is about 181 wet dates a year.
The widest day
May 7 carries the biggest normal gap between afternoon and dawn, 21°F between the normal high and the normal low.

Where Boonville Stands Nationally
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.
Among the steadiest day-night climates ranked: even the widest normal daily swing holds to roughly 21°F.
Boonville earns 2 nationally notable standings (outer quintiles) against 6,860 NOAA 1991–2020 normals stations; only those extremes render.

Boonville spreads its precipitation across the year
Neither half of the year dominates here: June through August take 25% of the annual total and December through February 24%, 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 49.1°F gap between its warmest and coldest month.
The gap between the wettest and driest month still matters: October averages 6.1" and February 4.0". The three wettest months together take 29% 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.
How Boonville's precipitation splits across the calendar
About 181 days a year record measurable precipitation here, carrying 58.2" between them, or roughly 0.32 inches on a typical wet day. That sits in the middle band: neither the many-light-days pattern of the Pacific Northwest and the Great Lakes, nor the few-heavy-events pattern of the Gulf and the desert Southwest.
A wet day is one recording at least 0.01 inches. These are 1991-2020 normals: they describe an average year and say nothing about the heaviest single storm on record.
Winter brings real snow to Boonville
Boonville averages 164.0 inches of snowfall a year, with January the snowiest month on the normals, spread across roughly 68 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: 164.0 inches of depth.
- Days recording measurable snow: about 68 a year.
- At a rough ten-to-one melt ratio, snow accounts for on the order of 28% of the year's precipitation.

Snow and freeze rhythm
When cold and snow define Boonville
heating led · wet · mid swing
Boonville's energy balance leans toward cold weather: 8,531 annual heating degree days against 194 for cooling. Its 49.1°F seasonal range still makes the monthly rows more useful than the annual average alone.
Only about 147 days are frost-free in a normal year. That short interval is consistent with the cold-season signal, but the measure does not predict the exact first or last freeze in any one year.
