The year, day by day
Summer here tops out rather than builds: the warmest normal high is 85°F around July 25, short of 90°F on every date, while 199 dates carry a normal low at or below freezing, the coldest 8°F near January 1.
The freezing stretch
The normal low stays at or below 32°F into April 28, then returns to freezing around October 13, covering 199 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 27, when 28% of years recorded at least a hundredth of an inch. The driest is September 4 at 14%. Summed across the calendar, that is about 71 wet dates a year.
The widest day
July 25 carries the biggest normal gap between afternoon and dawn, 34°F between the normal high and the normal low.

Where Mackay Lost Rvr Ranger Station Stands Nationally
Winters bite deep and often: the normal nightly low dips to freezing or below on around 199 nights a year, placing this among the most frost-prone tenth of ranked stations.
Aridity defines the water calendar: about 10 inches in a normal year lands this among the driest tenth of ranked stations.
Mackay Lost Rvr Ranger Station earns 2 nationally notable standings (outer quintiles) against 6,860 NOAA 1991–2020 normals stations; only those extremes render.

Mackay Lost Rvr Ranger Station spreads its precipitation across the year
Neither half of the year dominates here: June through August take 28% of the annual total and December through February 22%, with neither reaching the 35% that would mark a distinct wet season. Mackay Lost Rvr Ranger Station has no dry season to plan around, though it does carry a wide 47.6°F gap between its warmest and coldest month.
The gap between the wettest and driest month still matters: June averages 1.4" and February 0.5". 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.
Mackay Lost Rvr Ranger Station is dry, and what does fall arrives gently
Only about 71 days a year record measurable precipitation here, 19% of the calendar, and they carry 9.9" between them. At roughly 0.14 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 8 wet days; the driest is July at about 5.
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 Mackay Lost Rvr Ranger Station's limited precipitation lands
heating led · dry · mid swing
Mackay Lost Rvr Ranger Station's energy balance leans toward cold weather: 8,438 annual heating degree days against 171 for cooling. Its 47.6°F seasonal range still makes the monthly rows more useful than the annual average alone.
Only about 111 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 Mackay Lost Rvr Ranger Station's middle-range seasonal profile. The measured spread is 47.6°F. The annual average is 42°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Mackay Lost Rvr Ranger Station's cold-season load does not imply a wet climate. Annual precipitation is 9.9 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.

Data Sources
Data source: NOAA U.S. Climate Normals v1.0.1 (1991-2020). All figures on this page are from Mackay Lost Rvr Ranger Station's primary station: MACKAY LOST RVR RS (USC00105462). 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 Mackay Lost Rvr Ranger Station; facility counts that depend on place identity are therefore an upper bound, not a municipal census.
On this page every temperature, precipitation, and derived score for Mackay Lost Rvr Ranger Station comes from its primary NOAA station record.
