The year, day by day
Marion Rsvr works both ends of the calendar. Normal highs climb to 93°F by July 22 and hold at or above 90°F on 55 dates, then normal lows drop to freezing or below on 109 dates, bottoming at 21°F around January 16.
When the heat sits
Normal highs reach 90°F from June 28 through August 21, covering 55 dates. The broader mild season, normal highs of 70°F or more, runs April 27 to October 17.
This counts calendar dates whose 1991–2020 normal high reaches 90°F. It is a smaller number than the 90°F+ day counts in the monthly table above, which measure how often the threshold was actually crossed in a typical year. A date can average 88°F and still exceed 90°F in half of all years.
The freezing stretch
The normal low stays at or below 32°F into March 8, then returns to freezing around November 21, covering 109 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 12, when 31% of years recorded at least a hundredth of an inch. The driest is January 14 at 12%. Summed across the calendar, that is about 76 wet dates a year.
The widest day
October 6 carries the biggest normal gap between afternoon and dawn, 24°F between the normal high and the normal low.

Marion Rsvr runs a summer-peaked wet season
38% of Marion Rsvr'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 5.2", on a wide 50.1°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 41% of the annual total between them.
- Driest month: January at 0.8".
- Winter share: 9% 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.
When it rains in Marion Rsvr, it arrives in quantity
33.9" of precipitation falls across only about 76 wet days here, averaging 0.45 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 76 a year, 21% of all days
- Average depth per wet day
- 0.45 inches

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 Marion Rsvr's climate pattern fits together
heating led · moderate · mid swing
Marion Rsvr's energy balance leans toward cold weather: 4,725 annual heating degree days against 1,707 for cooling. Its 50.1°F seasonal range still makes the monthly rows more useful than the annual average alone.
Marion Rsvr's frost-free season lasts about 205 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 Marion Rsvr's middle-range seasonal profile. The measured spread is 50.1°F. The annual average is 57°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Marion Rsvr's 33.9 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 Marion Rsvr'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 Marion Rsvr, 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 Marion Rsvr's primary station: MARION RSVR (USC00145039). 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 Marion Rsvr; 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 Marion Rsvr comes from its primary NOAA station record.
