Bluff'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
Bluff works both ends of the calendar. Normal highs climb to 96°F by July 9 and hold at or above 90°F on 83 dates, then normal lows drop to freezing or below on 137 dates, bottoming at 19°F around January 1.
When the heat sits
Normal highs reach 90°F from June 9 through August 30, covering 83 dates. The broader mild season, normal highs of 70°F or more, runs April 10 to October 16.
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 16, then returns to freezing around November 1, covering 137 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 1, when 17% of years recorded at least a hundredth of an inch. The driest is June 15 at 5%. Summed across the calendar, that is about 43 wet dates a year.
The widest day
June 14 carries the biggest normal gap between afternoon and dawn, 37°F between the normal high and the normal low.

Where Bluff Stands Nationally
Aridity defines the water calendar: about 7 inches in a normal year lands this among the driest tenth of ranked stations.
Day-to-night contrast is extreme by national standards — the widest normal daily swing reaches about 37°F, sharper than nine in ten ranked stations see.
Bluff earns 2 nationally notable standings (outer quintiles) against 6,860 NOAA 1991–2020 normals stations; only those extremes render.

Bluff spreads its precipitation across the year
Neither half of the year dominates here: June through August take 24% of the annual total and December through February 29%, with neither reaching the 35% that would mark a distinct wet season. Bluff has no dry season to plan around, though it does carry a wide 48.4°F gap between its warmest and coldest month.
The gap between the wettest and driest month still matters: August averages 0.9" and June 0.2". The three wettest months together take 36% 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.
Bluff is dry, and what does fall arrives gently
Only about 43 days a year record measurable precipitation here, 12% of the calendar, and they carry 7.3" between them. At roughly 0.17 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 August 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.
Snow reaches Bluff, but rarely amounts to much
The normals record 7.4 inches of snow a year here, most likely in December. That is a real but marginal amount: enough that snow is part of the local record, not enough to define the winter.
A figure in this range usually reflects a handful of events that melt quickly rather than a season of accumulation; about 5 days a year record any measurable snow at all.
NOAA 1991-2020 normals. An average across thirty years can smooth away a single heavy winter, so a small annual figure does not mean a significant snowfall is impossible.

Scarce-water calendar
Where Bluff's limited precipitation lands
heating led · dry · mid swing
Bluff's energy balance leans toward cold weather: 4,886 annual heating degree days against 1,321 for cooling. Its 48.4°F seasonal range still makes the monthly rows more useful than the annual average alone.
Bluff's frost-free season lasts about 172 days, a middle-length window whose endpoints matter more than the annual average. It describes freeze probability, not year-specific planting conditions.
July and December mark the typical warm and cold ends of the calendar in Bluff's middle-range seasonal profile. The measured spread is 48.4°F. The annual average is 55°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Bluff's cold-season load does not imply a wet climate. Annual precipitation is 7.3 inches, which places the station in PlainClimate's dry range. Annual snowfall totals 7.4 inches. The snowfall and rainfall fields should be read separately rather than inferred from temperature.
