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 186 dates carry a normal low at or below freezing, the coldest 12°F near December 22.
The freezing stretch
The normal low stays at or below 32°F into April 18, then returns to freezing around October 16, 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.
The widest day
September 7 carries the biggest normal gap between afternoon and dawn, 32°F between the normal high and the normal low.

Where Whalen Dam Usbr 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.
A drier-than-most normal water year — around 14 inches, below what four out of five ranked stations collect.
Whalen Dam Usbr earns 2 nationally notable standings (outer quintiles) against 6,860 NOAA 1991–2020 normals stations; only those extremes render.
Monthly Precipitation
Average monthly rainfall
Whalen Dam Usbr runs a summer-peaked wet season
36% of Whalen Dam Usbr's yearly precipitation falls in June, July and August alone, against the 25% an evenly spread year would give those three months. The wettest month is May at 2.7", on a wide 46.2°F gap between its warmest and coldest month. Warm-season convection and, across the Southwest, the North American monsoon produce this shape: rain arrives in short heavy bursts during the hottest part of the year rather than as long cool-season soaking.
- Wettest three months: May, June, July, taking 47% of the annual total between them.
- Driest month: January at 0.3".
- Winter share: 7% falls in December, January and February.
Shares are computed from this station's own 1991-2020 monthly precipitation normals. A summer-peaked label means the June-August share reaches 35%; it describes timing across an average year, not any single season, and says nothing about how heavy an individual storm can be.

Scarce-water calendar
Where Whalen Dam Usbr's limited precipitation lands
heating led · dry · mid swing
Whalen Dam Usbr's energy balance leans toward cold weather: 6,731 annual heating degree days against 619 for cooling. Its 46.2°F seasonal range still makes the monthly rows more useful than the annual average alone.
Only about 149 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 Whalen Dam Usbr's middle-range seasonal profile. The measured spread is 46.2°F. The annual average is 48°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Whalen Dam Usbr's cold-season load does not imply a wet climate. Annual precipitation is 14.1 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 Whalen Dam Usbr's primary station: WHALEN DAM USBR (USC00489604). 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 Whalen Dam Usbr; 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 Whalen Dam Usbr comes from its primary NOAA station record.
