The year, day by day
Summer here tops out rather than builds: the warmest normal high is 84°F around July 19, short of 90°F on every date, while 159 dates carry a normal low at or below freezing, the coldest 10°F near January 21.
The freezing stretch
The normal low stays at or below 32°F into April 10, then returns to freezing around November 4, covering 159 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
June 22 carries the biggest normal gap between afternoon and dawn, 25°F between the normal high and the normal low.

Monthly Precipitation
Average monthly rainfall
Richfield spreads its precipitation across the year
Neither half of the year dominates here: June through August take 34% of the annual total and December through February 15%, with neither reaching the 35% that would mark a distinct wet season. Richfield has no dry season to plan around, though it does carry a wide 52.6°F gap between its warmest and coldest month.
The gap between the wettest and driest month still matters: June averages 4.7" and January 1.7". The three wettest months together take 35% 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 Richfield's climate pattern fits together
heating led · moderate · mid swing
Richfield's energy balance leans toward cold weather: 7,284 annual heating degree days against 580 for cooling. Its 52.6°F seasonal range still makes the monthly rows more useful than the annual average alone.
Richfield's frost-free season lasts about 169 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 Richfield's middle-range seasonal profile. The measured spread is 52.6°F. The annual average is 47°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Richfield's 36.8 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 Richfield'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 Richfield, not an official NOAA class or a year-ahead forecast.
