The year, day by day

Summer here tops out rather than builds: the warmest normal high is 89°F around July 22, short of 90°F on every date, while 108 dates carry a normal low at or below freezing, the coldest 22°F near January 16.

The freezing stretch

The normal low stays at or below 32°F into March 11, then returns to freezing around November 25, covering 108 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 5, when 38% of years recorded at least a hundredth of an inch. The driest is September 11 at 21%. Summed across the calendar, that is about 102 wet dates a year.

The widest day

October 5 carries the biggest normal gap between afternoon and dawn, 25°F between the normal high and the normal low.

Festus spreads its precipitation across the year

Neither half of the year dominates here: June through August take 28% of the annual total and December through February 18%, with neither reaching the 35% that would mark a distinct wet season. Festus has no dry season to plan around, though it does carry a wide 46.1°F gap between its warmest and coldest month.

The gap between the wettest and driest month still matters: April averages 4.9" and February 2.5". The three wettest months together take 33% 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 Festus, it arrives in quantity

43.6" of precipitation falls across only about 101 wet days here, averaging 0.43 inches each. Fewer days carry more water: the year's total is delivered in comparatively heavy events rather than persistent damp.

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.

Snow reaches Festus, but rarely amounts to much

The normals record 9.2 inches of snow a year here, most likely in February. That is a real but marginal amount: enough that snow is part of the local record, not enough to define the winter.

A figure in this range usually reflects a handful of events that melt quickly rather than a season of accumulation; about 6 days a year record any measurable snow at all.

NOAA 1991-2020 normals. An average across thirty years can smooth away a single heavy winter, so a small annual figure does not mean a significant snowfall is impossible.

Data-derived climate profile

How Festus's climate pattern fits together

heating led · moderate · mid swing

Festus's energy balance leans toward cold weather: 4,700 annual heating degree days against 1,352 for cooling. Its 46.1°F seasonal range still makes the monthly rows more useful than the annual average alone.

Festus's frost-free season lasts about 200 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 Festus's middle-range seasonal profile. The measured spread is 46.1°F. The annual average is 56°F. Neither the annual mean nor one extreme month represents the full calendar on its own.

Festus's 43.6 inches of annual precipitation falls in PlainClimate's middle band, so “wet” or “dry” is not the leading description. Annual snowfall totals 9.2 inches. Temperature balance and the calendar distribution carry more information than the annual moisture label alone.

These labels group NOAA 1991-2020 normals from Festus'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 Festus, not an official NOAA class or a year-ahead forecast.

Questions about Festus's climate

How much rain does Festus get?
Festus receives 43.6 inches of precipitation, including 9.2 inches of snow. Based on NOAA 30-year climate normals (1991-2020).
How many days above 90°F does Festus get?
Festus averages about 38 days a year at or above 90°F, concentrated in July and the months either side of it. That is a count of days reaching the threshold, not a measure of how far above it they go.
How much energy does heating and cooling require in Festus?
Festus has 4,700 heating degree days and 1,352 cooling degree days annually, a heating-dominated climate. Degree-day definitions: reading weather data.
