The year, day by day
Summer here tops out rather than builds: the warmest normal high is 87°F around July 6, short of 90°F on every date, while 124 dates carry a normal low at or below freezing, the coldest 19°F near January 23.
The freezing stretch
The normal low stays at or below 32°F into March 21, then returns to freezing around November 19, covering 124 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 April 24, when 44% of years recorded at least a hundredth of an inch. The driest is September 6 at 26%. Summed across the calendar, that is about 129 wet dates a year.
The widest day
September 23 carries the biggest normal gap between afternoon and dawn, 24°F between the normal high and the normal low.

Dayton Mcd 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 21%, with neither reaching the 35% that would mark a distinct wet season. Dayton Mcd has no dry season to plan around, though it does carry a wide 48°F gap between its warmest and coldest month.
The gap between the wettest and driest month still matters: April averages 4.5" and February 2.4". 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.
How Dayton Mcd's precipitation splits across the calendar
About 128 days a year record measurable precipitation here, carrying 41.6" 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 Dayton Mcd
Dayton Mcd averages 12.3 inches of snowfall a year, with January the snowiest month on the normals, spread across roughly 10 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: 12.3 inches of depth.
- Days recording measurable snow: about 10 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.

Snow and freeze rhythm
When cold and snow define Dayton Mcd
heating led · moderate · mid swing
Dayton Mcd's energy balance leans toward cold weather: 5,432 annual heating degree days against 1,191 for cooling. Its 48.0°F seasonal range still makes the monthly rows more useful than the annual average alone.
Dayton Mcd's frost-free season lasts about 190 days, a middle-length window whose endpoints matter more than the annual average. It describes freeze probability, not year-specific planting conditions.

Data Sources
Data source: NOAA U.S. Climate Normals v1.0.1 (1991-2020). All figures on this page are from Dayton Mcd's primary station: DAYTON MCD (USC00332067). For informational purposes only.
Place identity: U.S. Census Bureau 2024 Gazetteer places. The conservative exact name-and-state crosswalk finds no Census place match, so PlainClimate treats this as a station-mapped location and does not claim it is a municipality. No exact Gazetteer row for Dayton Mcd; facility counts that depend on place identity are therefore an upper bound, not a municipal census.
