The year, day by day
Graham works both ends of the calendar. Normal highs climb to 99°F by July 30 and hold at or above 90°F on 106 dates, then normal lows drop to freezing or below on 57 dates, bottoming at 29°F around January 18.
When the heat sits
Normal highs reach 90°F from June 3 through September 16, covering 106 dates. The broader mild season, normal highs of 70°F or more, runs March 16 to November 10.
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 February 12, then returns to freezing around December 18, covering 57 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 June 5, when 22% of years recorded at least a hundredth of an inch. The driest is January 14 at 10%. Summed across the calendar, that is about 59 wet dates a year.
The widest day
November 7 carries the biggest normal gap between afternoon and dawn, 29°F between the normal high and the normal low.

Where Graham Stands Nationally
Summers here run among the most heat-heavy normals calendars in the country: on about 106 days a year the normal daily high itself reaches 90°F — a count fewer than one station in ten exceeds.
Graham earns one nationally notable standing (outer quintile) against 6,860 NOAA 1991–2020 normals stations, middle-of-the-pack metrics stay silent here.

Graham spreads its precipitation across the year
Neither half of the year dominates here: June through August take 27% of the annual total and December through February 16%, with neither reaching the 35% that would mark a distinct wet season. Graham has no dry season to plan around, though it does carry a 41.7°F seasonal spread.
The gap between the wettest and driest month still matters: May averages 3.8" and January 1.2". The three wettest months together take 38% 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 Graham, it arrives in quantity
30.0" of precipitation falls across only about 59 wet days here, averaging 0.51 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 59 a year, 16% of all days
- Average depth per wet day

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 Graham's climate pattern fits together
mixed demand · moderate · mid swing
July and January mark the typical warm and cold ends of the calendar in Graham's middle-range seasonal profile. The measured spread is 41.7°F. The annual average is 65°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Heating and cooling both register in Graham's normal, at 2,723 and 2,584 degree days respectively. Neither total exceeds the other by more than two to one, so the record is better read as a mixed-demand calendar than as heating-led or cooling-led.
A roughly 218-day frost-free season sits inside this mixed heating-and-cooling profile. Start and end dates matter because both sides of the thermostat register during a normal year.
Graham's 30.0 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 Graham's primary station, where heating and cooling demand are close enough that neither season sets the character on its own. On a balanced station like Graham, the bands are descriptive ranges rather than an official NOAA classification or a forecast.
