The year, day by day
Farmington works both ends of the calendar. Normal highs climb to 92°F by July 23 and hold at or above 90°F on 33 dates, then normal lows drop to freezing or below on 118 dates, bottoming at 21°F around January 3.
When the heat sits
Normal highs reach 90°F from July 11 through August 12, covering 33 dates. The broader mild season, normal highs of 70°F or more, runs May 16 to October 4.
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 9, then returns to freezing around November 13, covering 118 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 16, when 30% of years recorded at least a hundredth of an inch. The driest is July 9 at 10%. Summed across the calendar, that is about 81 wet dates a year.
The widest day
July 29 carries the biggest normal gap between afternoon and dawn, 28°F between the normal high and the normal low.

Farmington spreads its precipitation across the year
Neither half of the year dominates here: June through August take 14% of the annual total and December through February 28%, with neither reaching the 35% that would mark a distinct wet season. Farmington has no dry season to plan around, though it does carry a wide 48.3°F gap between its warmest and coldest month.
The gap between the wettest and driest month still matters: May averages 2.7" and July 0.7". The three wettest months together take 35% 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 Farmington's precipitation splits across the calendar
About 80 days a year record measurable precipitation here, carrying 20.6" between them, or roughly 0.26 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 Farmington
Farmington averages 49.6 inches of snowfall a year, with January the snowiest month on the normals, spread across roughly 17 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: 49.6 inches of depth.
- Days recording measurable snow: about 17 a year.
- At a rough ten-to-one melt ratio, snow accounts for on the order of 24% 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 Farmington
heating led · moderate · mid swing
Farmington's energy balance leans toward cold weather: 5,709 annual heating degree days against 1,007 for cooling. Its 48.3°F seasonal range still makes the monthly rows more useful than the annual average alone.
Farmington's frost-free season lasts about 183 days, a middle-length window whose endpoints matter more than the annual average. It describes freeze probability, not year-specific planting conditions.
