The year, day by day
Summer here tops out rather than builds: the warmest normal high is 89°F around July 23, short of 90°F on every date, while 176 dates carry a normal low at or below freezing, the coldest 20°F near December 18.
The freezing stretch
The normal low stays at or below 32°F into April 15, then returns to freezing around October 23, covering 176 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 December 22, when 34% of years recorded at least a hundredth of an inch. The driest is August 17 at 9%. Summed across the calendar, that is about 89 wet dates a year.
The widest day
July 10 carries the biggest normal gap between afternoon and dawn, 34°F between the normal high and the normal low.

Where Murphy Stands Nationally
Aridity defines the water calendar: about 11 inches in a normal year lands this among the driest tenth of ranked stations.
Daily temperature swings run wider than most of the country, peaking near 34°F between the normal high and low.
Murphy earns 2 nationally notable standings (outer quintiles) against 6,860 NOAA 1991–2020 normals stations; only those extremes render.

Murphy spreads its precipitation across the year
Neither half of the year dominates here: June through August take 15% of the annual total and December through February 31%, with neither reaching the 35% that would mark a distinct wet season. Murphy has no dry season to plan around, though it does carry a 41.5°F seasonal spread.
The gap between the wettest and driest month still matters: May averages 1.4" and August 0.3". 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.
Murphy is dry, and what does fall arrives gently
Only about 89 days a year record measurable precipitation here, 24% of the calendar, and they carry 11.3" 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 December at about 11 wet days; the driest is August at about 3.
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 Murphy's limited precipitation lands
heating led · dry · mid swing
Murphy's energy balance leans toward cold weather: 6,473 annual heating degree days against 457 for cooling. Its 41.5°F seasonal range still makes the monthly rows more useful than the annual average alone.
Only about 136 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 December mark the typical warm and cold ends of the calendar in Murphy's middle-range seasonal profile. The measured spread is 41.5°F. The annual average is 48°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Murphy's cold-season load does not imply a wet climate. Annual precipitation is 11.3 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.
