The year, day by day
Summer here tops out rather than builds: the warmest normal high is 79°F around July 12, short of 90°F on every date, while 205 dates carry a normal low at or below freezing, the coldest 9°F near January 23.
The freezing stretch
The normal low stays at or below 32°F into May 6, then returns to freezing around October 15, covering 205 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 August 3, when 54% of years recorded at least a hundredth of an inch. The driest is June 10 at 22%. Summed across the calendar, that is about 113 wet dates a year.
The widest day
June 20 carries the biggest normal gap between afternoon and dawn, 33°F between the normal high and the normal low.

Where Lemon Dam Stands Nationally
Winters bite deep and often: the normal nightly low dips to freezing or below on around 205 nights a year, placing this among the most frost-prone tenth of ranked stations.
Daily temperature swings run wider than most of the country, peaking near 33°F between the normal high and low.
Lemon Dam earns 2 nationally notable standings (outer quintiles) against 6,860 NOAA 1991–2020 normals stations; only those extremes render.

Lemon Dam spreads its precipitation across the year
Neither half of the year dominates here: June through August take 26% of the annual total and December through February 27%, with neither reaching the 35% that would mark a distinct wet season. Lemon Dam has no dry season to plan around, though it does carry a 40.7°F seasonal spread.
The gap between the wettest and driest month still matters: August averages 3.5" and June 0.9". 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 Lemon Dam's precipitation splits across the calendar
About 112 days a year record measurable precipitation here, carrying 28.3" between them, or roughly 0.25 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 Lemon Dam
Lemon Dam averages 131.0 inches of snowfall a year, with January the snowiest month on the normals, spread across roughly 43 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: 131.0 inches of depth.
- Days recording measurable snow: about 43 a year.
- At a rough ten-to-one melt ratio, snow accounts for on the order of 46% 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 Lemon Dam
heating led · moderate · mid swing
Lemon Dam's energy balance leans toward cold weather: 8,064 annual heating degree days against 48 for cooling. Its 40.7°F seasonal range still makes the monthly rows more useful than the annual average alone.
Only about 125 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.

Data source: NOAA U.S. Climate Normals v1.0.1 (1991-2020). All figures on this page are from Lemon Dam's primary station: LEMON DAM (USC00054934). 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 Lemon Dam; facility counts that depend on place identity are therefore an upper bound, not a municipal census.
