The year, day by day
Summer here tops out rather than builds: the warmest normal high is 81°F around July 17, short of 90°F on every date, while 182 dates carry a normal low at or below freezing, the coldest 3°F near January 24.
The freezing stretch
The normal low stays at or below 32°F into April 22, then returns to freezing around October 24, covering 182 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 June 1, when 40% of years recorded at least a hundredth of an inch. The driest is February 20 at 25%. Summed across the calendar, that is about 122 wet dates a year.
The widest day
May 14 carries the biggest normal gap between afternoon and dawn, 25°F between the normal high and the normal low.

Iron Mtn-kingsford Wwtp spreads its precipitation across the year
Neither half of the year dominates here: June through August take 33% of the annual total and December through February 14%, with neither reaching the 35% that would mark a distinct wet season. Iron Mtn-kingsford Wwtp has no dry season to plan around, though it does carry a wide 54.3°F gap between its warmest and coldest month.
The gap between the wettest and driest month still matters: June averages 3.7" and February 1.1". 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.
How Iron Mtn-kingsford Wwtp's precipitation splits across the calendar
About 122 days a year record measurable precipitation here, carrying 31.5" 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 Iron Mtn-kingsford Wwtp
Iron Mtn-kingsford Wwtp averages 61.0 inches of snowfall a year, with January the snowiest month on the normals, spread across roughly 36 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: 61.0 inches of depth.
- Days recording measurable snow: about 36 a year.
- At a rough ten-to-one melt ratio, snow accounts for on the order of 19% 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 Iron Mtn-kingsford Wwtp
heating led · moderate · mid swing
Iron Mtn-kingsford Wwtp's energy balance leans toward cold weather: 8,522 annual heating degree days against 372 for cooling. Its 54.3°F seasonal range still makes the monthly rows more useful than the annual average alone.
Only about 137 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.

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 Iron Mtn-kingsford Wwtp; facility counts that depend on place identity are therefore an upper bound, not a municipal census.
