The year, day by day
Summer here tops out rather than builds: the warmest normal high is 77°F around July 12, short of 90°F on every date, while 176 dates carry a normal low at or below freezing, the coldest 4°F near January 30.
The freezing stretch
The normal low stays at or below 32°F into April 23, then returns to freezing around October 31, 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.
The widest day
May 28 carries the biggest normal gap between afternoon and dawn, 23°F between the normal high and the normal low.

Monthly Precipitation
Average monthly rainfall
Rapid Rvr spreads its precipitation across the year
Neither half of the year dominates here: June through August take 29% of the annual total and December through February 15%, with neither reaching the 35% that would mark a distinct wet season. Rapid Rvr has no dry season to plan around, though it does carry a wide 50.7°F gap between its warmest and coldest month.
The gap between the wettest and driest month still matters: July averages 3.6" and February 1.3". The three wettest months together take 34% 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.

Data-derived climate profile
How Rapid Rvr's climate pattern fits together
heating led · moderate · mid swing
Rapid Rvr's energy balance leans toward cold weather: 8,555 annual heating degree days against 218 for cooling. Its 50.7°F seasonal range still makes the monthly rows more useful than the annual average alone.
Only about 139 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 Rapid Rvr's middle-range seasonal profile. The measured spread is 50.7°F. The annual average is 42°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Rapid Rvr's 31.3 inches of annual precipitation falls in PlainClimate's middle band, so “wet” or “dry” is not the leading description. Snowfall is not added to the interpretation because its annual value is missing. Temperature balance and the calendar distribution carry more information than the annual moisture label alone.
These labels group NOAA 1991-2020 normals from Rapid Rvr'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 Rapid Rvr, not an official NOAA class or a year-ahead forecast.

Data Sources
Data source: NOAA U.S. Climate Normals v1.0.1 (1991-2020). All figures on this page are from Rapid Rvr's primary station: RAPID RVR 4SSE (USC00206840). 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 Rapid Rvr; 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 Rapid Rvr comes from its primary NOAA station record.
