The year, day by day
Summer here tops out rather than builds: the warmest normal high is 89°F around July 24, short of 90°F on every date, while 103 dates carry a normal low at or below freezing, the coldest 22°F near January 17.
The freezing stretch
The normal low stays at or below 32°F into March 6, then returns to freezing around November 25, covering 103 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 6, when 42% of years recorded at least a hundredth of an inch. The driest is December 21 at 24%. Summed across the calendar, that is about 112 wet dates a year.
The widest day
April 6 carries the biggest normal gap between afternoon and dawn, 23°F between the normal high and the normal low.

Vichy Rolla National 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. Vichy Rolla National has no dry season to plan around, though it does carry a wide 45.8°F gap between its warmest and coldest month.
The gap between the wettest and driest month still matters: May averages 5.3" and February 2.1". 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.
When it rains in Vichy Rolla National, it arrives in quantity
43.1" of precipitation falls across only about 111 wet days here, averaging 0.39 inches each. Fewer days carry more water: the year's total is delivered in comparatively heavy events rather than persistent damp.
- Days with measurable precipitation
- about 111 a year, 30% of all days
- Average depth per wet day
- 0.39 inches
- Most wet days
- May, about 13
- Fewest wet days
- December, about 7
A wet day is one recording at least 0.01 inches. These are 1991-2020 normals: they describe an average year, and a per-day average is not a forecast of any individual storm.

Data-derived climate profile
How Vichy Rolla National's climate pattern fits together
heating led · moderate · mid swing
Vichy Rolla National's energy balance leans toward cold weather: 4,721 annual heating degree days against 1,307 for cooling. Its 45.8°F seasonal range still makes the monthly rows more useful than the annual average alone.
Vichy Rolla National's frost-free season lasts about 196 days, a middle-length window whose endpoints matter more than the annual average. It describes freeze probability, not year-specific planting conditions.
July and January mark the typical warm and cold ends of the calendar in Vichy Rolla National's middle-range seasonal profile. The measured spread is 45.8°F. The annual average is 56°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Vichy Rolla National's 43.1 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 Vichy Rolla National'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 Vichy Rolla National, 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 Vichy Rolla National's primary station: VICHY ROLLA NATIONAL AP (USW00013997). 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 Vichy Rolla National; 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 Vichy Rolla National comes from its primary NOAA station record.
