Mercury's normals sit in a dry climate class: BWk
Annual precipitation falls well below the aridity threshold for this temperature regime, so the normals classify as cold desert (BWk). Class BWk is the Peel et al. (2007) label for this station's monthly mean temperature and precipitation normals: dry (arid or semi-arid), specifically cold desert.

The year, day by day
Mercury works both ends of the calendar. Normal highs climb to 100°F by July 14 and hold at or above 90°F on 104 dates, then normal lows drop to freezing or below on 30 dates, bottoming at 31°F around December 18.
When the heat sits
Normal highs reach 90°F from June 5 through September 16, covering 104 dates. The broader mild season, normal highs of 70°F or more, runs April 2 to November 2.
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 January 4, then returns to freezing around December 6, covering 30 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 February 22, when 17% of years recorded at least a hundredth of an inch. The driest is June 7 at 4%. Summed across the calendar, that is about 39 wet dates a year.
The widest day
June 22 carries the biggest normal gap between afternoon and dawn, 30°F between the normal high and the normal low.

Where Mercury Stands Nationally
Summers here run among the most heat-heavy normals calendars in the country: on about 104 days a year the normal daily high itself reaches 90°F — a count fewer than one station in ten exceeds.
Aridity defines the water calendar: about 5 inches in a normal year lands this among the driest tenth of ranked stations.
Mercury earns 2 nationally notable standings (outer quintiles) against 6,860 NOAA 1991–2020 normals stations; only those extremes render.

Mercury's wet season runs through the cold months
December, January and February carry 44% of the year's precipitation here, while June through August contribute 15%. That is the cool-season-dominant pattern of the West Coast and the higher inland West, where storm tracks swing south in winter and summer turns dry; the thermometer meanwhile shows a 42.5°F seasonal spread.
- Wettest month
- February, 1.0"
- Driest month
- June, 0.1"
- Wettest three months
- February, January, December (44% of the year)
Shares are computed from this station's own 1991-2020 monthly precipitation normals. A cool-season label means the December-February share reaches 35%. Where snow falls, the monthly figures above report liquid-equivalent precipitation, so a wet winter month is not necessarily a rainy one.
Mercury is dry, and what does fall arrives gently
Only about 40 days a year record measurable precipitation here, 11% of the calendar, and they carry 5.3" between them. At roughly 0.13 inches on an average wet day, this is not the damp drizzle of a marine climate; it is an arid record in which precipitation is both uncommon and light when it appears.
The wettest month by count is January at about 5 wet days; the driest is June at about 1.
A low per-event average in a dry record is a statement about typical days only. Arid regions can still take a large share of a year's total from a single convective storm, which a normal cannot show.
A wet day is one recording at least 0.01 inches. These are 1991-2020 normals: they describe an average year, not the extremes within it.

Scarce-water calendar
Where Mercury's limited precipitation lands
mixed demand · dry · mid swing
Local precipitation is sparse in this otherwise mixed profile. The station reports 5.3 inches annually, within PlainClimate's dry band. Snowfall is not added to the interpretation because its annual value is missing. The monthly distribution matters because the total alone does not reveal the timing.
July and December mark the typical warm and cold ends of the calendar in Mercury's middle-range seasonal profile. The measured spread is 42.5°F. The annual average is 63°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Heating and cooling both register in Mercury's normal, at 2,955 and 2,240 degree days respectively. Neither total exceeds the other by more than two to one, so the record is better read as a mixed-demand calendar than as heating-led or cooling-led.
Mercury has a long frost-free window of roughly 254 days, but the dry annual profile is a separate constraint. Growing-season length says when freezes are unlikely, not whether rainfall is sufficient.

Data source: NOAA U.S. Climate Normals v1.0.1 (1991-2020). All figures on this page are from Mercury's primary station: MERCURY 3 SSW (USW00053136). 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 Mercury; facility counts that depend on place identity are therefore an upper bound, not a municipal census.
