The year, day by day
Summer here tops out rather than builds: the warmest normal high is 88°F around July 21, short of 90°F on every date, while 186 dates carry a normal low at or below freezing, the coldest 13°F near January 1.
The freezing stretch
The normal low stays at or below 32°F into April 21, then returns to freezing around October 19, covering 186 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 May 7, when 44% of years recorded at least a hundredth of an inch. The driest is July 9 at 20%. Summed across the calendar, that is about 101 wet dates a year.
The widest day
July 9 carries the biggest normal gap between afternoon and dawn, 30°F between the normal high and the normal low.

Where Lander Stands Nationally
Freezing is routine here by normals standards — the normal low reaches 32°F or colder on about 186 nights a year, more than most ranked stations.
Lander earns one nationally notable standing (outer quintile) against 6,860 NOAA 1991–2020 normals stations, middle-of-the-pack metrics stay silent here.

Lander spreads its precipitation across the year
Neither half of the year dominates here: June through August take 19% of the annual total and December through February 17%, with neither reaching the 35% that would mark a distinct wet season. Lander has no dry season to plan around, though it does carry a wide 47.4°F gap between its warmest and coldest month.
The gap between the wettest and driest month still matters: May averages 2.8" and July 0.8". The three wettest months together take 42% 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.
Lander is dry, and what does fall arrives gently
Only about 102 days a year record measurable precipitation here, 28% of the calendar, and they carry 16.0" between them. At roughly 0.16 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 May at about 14 wet days; the driest is November at about 7.
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.

Data-derived climate profile
How Lander's climate pattern fits together
heating led · dry · mid swing
Lander's energy balance leans toward cold weather: 7,495 annual heating degree days against 500 for cooling. Its 47.4°F seasonal range still makes the monthly rows more useful than the annual average alone.
Only about 142 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.
July and January mark the typical warm and cold ends of the calendar in Lander's middle-range seasonal profile. The measured spread is 47.4°F. The annual average is 46°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Lander's cold-season load does not imply a wet climate. Annual precipitation is 16.0 inches, which places the station in PlainClimate's dry range. Snowfall is not added to the interpretation because its annual value is missing. The snowfall and rainfall fields should be read separately rather than inferred from temperature.
These labels group NOAA 1991-2020 normals from Lander's primary station, so the winter figures are a thirty-year average and not a floor: a single hard season can run well below them. Treat each band as a descriptive range for Lander, not an official NOAA class or a year-ahead forecast.
