The year, day by day
The year in Calliham runs from a mild 42°F around January 3 to 100°F at the peak near August 6, and the normal low never reaches freezing on any date in the record.
When the heat sits
Normal highs reach 90°F from May 18 through September 28, covering 134 dates. The broader mild season, normal highs of 70°F or more, runs February 7 to December 7.
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.
No freezing date
Not one calendar date in the 1991–2020 record carries a normal low at or below 32°F. The coldest normal low of the year is 42°F around January 3.
Where the wet dates fall
The likeliest wet date is September 11, when 20% of years recorded at least a hundredth of an inch. The driest is August 2 at 10%. Summed across the calendar, that is about 58 wet dates a year.
The widest day
August 6 carries the biggest normal gap between afternoon and dawn, 26°F between the normal high and the normal low.

Where Calliham Stands Nationally
Summers here run among the most heat-heavy normals calendars in the country: on about 134 days a year the normal daily high itself reaches 90°F — a count fewer than one station in ten exceeds.
Calliham earns one nationally notable standing (outer quintile) against 6,860 NOAA 1991–2020 normals stations, middle-of-the-pack metrics stay silent here.

Calliham spreads its precipitation across the year
Neither half of the year dominates here: June through August take 26% of the annual total and December through February 16%, with neither reaching the 35% that would mark a distinct wet season. Calliham has no dry season to plan around, though it does carry a 31.4°F seasonal spread.
The gap between the wettest and driest month still matters: September averages 3.5" and December 1.3". The three wettest months together take 36% 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 Calliham, it arrives in quantity
25.6" of precipitation falls across only about 57 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 57 a year, 16% of all days
- Average depth per wet day
- 0.45 inches
- Most wet days
- September, about 6
- Fewest wet days
- August, about 3
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 Calliham, but rarely amounts to much
The normals record 0.3 inches of snow a year here, most likely in December. 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 0 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 Calliham's climate pattern fits together
cooling led · moderate · mid swing
Air-conditioning demand is the clearest thermal signal here. Calliham accumulates 3,593 cooling degree days, more than twice its 1,106 heating total; the monthly table shows when that imbalance builds rather than treating it as a year-round condition.
Calliham's 25.6 inches of annual precipitation falls in PlainClimate's middle band, so “wet” or “dry” is not the leading description. Recorded annual snowfall is negligible. Temperature balance and the calendar distribution carry more information than the annual moisture label alone.
August and January mark the typical warm and cold ends of the calendar in Calliham's middle-range seasonal profile. The measured spread is 31.4°F. The annual average is 72°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
The frost-free window extends for about 302 days. That is a long calendar measure, but it is not a forecast and does not combine heat, rainfall, soil, or local elevation into a planting recommendation.
These labels group NOAA 1991-2020 normals from Calliham's primary station, so the summer figures are a thirty-year average rather than a ceiling: individual years have run hotter and will again. For Calliham that means a descriptive range only — not an official NOAA classification and not a prediction for next summer.

Data source: NOAA U.S. Climate Normals v1.0.1 (1991-2020). All figures on this page are from Calliham's primary station: CALLIHAM (USC00411337). 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 Calliham; facility counts that depend on place identity are therefore an upper bound, not a municipal census.
