The year, day by day
Summer here tops out rather than builds: the warmest normal high is 89°F around July 30, short of 90°F on every date, while 88 dates carry a normal low at or below freezing, the coldest 26°F near January 15.
The freezing stretch
The normal low stays at or below 32°F into February 26, then returns to freezing around December 1, covering 88 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 March 10, when 36% of years recorded at least a hundredth of an inch. The driest is September 26 at 24%. Summed across the calendar, that is about 116 wet dates a year.
The widest day
March 30 carries the biggest normal gap between afternoon and dawn, 27°F between the normal high and the normal low.

Where Henderson Stands Nationally
This is one of the wettest normals climates ranked: about 62 inches of precipitation in a normal year, a total fewer than one station in ten surpasses.
Henderson earns one nationally notable standing (outer quintile) against 6,860 NOAA 1991–2020 normals stations, middle-of-the-pack metrics stay silent here.

Henderson spreads its precipitation across the year
Neither half of the year dominates here: June through August take 22% of the annual total and December through February 27%, with neither reaching the 35% that would mark a distinct wet season. Henderson has no dry season to plan around, though it does carry a 40.6°F seasonal spread.
The gap between the wettest and driest month still matters: April averages 6.4" and August 3.7". The three wettest months together take 30% 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 Henderson, it arrives in quantity
61.8" of precipitation falls across only about 115 wet days here, averaging 0.54 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 115 a year, 32% of all days
- Average depth per wet day
- 0.54 inches
- Most wet days

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 Henderson's climate pattern fits together
heating led · wet · mid swing
Henderson's energy balance leans toward cold weather: 3,898 annual heating degree days against 1,410 for cooling. Its 40.6°F seasonal range still makes the monthly rows more useful than the annual average alone.
Henderson's frost-free season lasts about 198 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 Henderson's middle-range seasonal profile. The measured spread is 40.6°F. The annual average is 58°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Alongside its heating load, Henderson carries 61.8 inches of precipitation in a normal year, inside PlainClimate's wet range. Snowfall is not added to the interpretation because its annual value is missing. That distinction matters because a wet annual total can arrive as rain, snow, or a mixture at different times.
These labels group NOAA 1991-2020 normals from Henderson'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 Henderson, not an official NOAA class or a year-ahead forecast.
