The year, day by day
The year in Allendale runs from a mild 33°F around January 7 to 92°F at the peak near July 10, and the normal low never reaches freezing on any date in the record.
When the heat sits
Normal highs reach 90°F from June 23 through August 9, covering 48 dates. The broader mild season, normal highs of 70°F or more, runs March 21 to November 11.
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 33°F around January 7.
Where the wet dates fall
The likeliest wet date is July 29, when 33% of years recorded at least a hundredth of an inch. The driest is November 9 at 17%. Summed across the calendar, that is about 92 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.

Allendale spreads its precipitation across the year
Neither half of the year dominates here: June through August take 32% of the annual total and December through February 24%, with neither reaching the 35% that would mark a distinct wet season. Allendale has no dry season to plan around, though it does carry a 34.6°F seasonal spread.
The gap between the wettest and driest month still matters: August averages 5.6" and April 3.1". The three wettest months together take 32% 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 Allendale, it arrives in quantity
48.8" of precipitation falls across only about 92 wet days here, averaging 0.53 inches each. Fewer days carry more water: the year's total is delivered in comparatively heavy events rather than persistent damp.

- about 92 a year, 25% of all 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 Allendale's climate pattern fits together
mixed demand · wet · mid swing
Water is prominent even though neither heating nor cooling wholly defines the record. Allendale averages 48.8 inches of precipitation a year. Snowfall is not added to the interpretation because its annual value is missing. The monthly table supplies the seasonal distribution hidden by that annual total.
July and January mark the typical warm and cold ends of the calendar in Allendale's middle-range seasonal profile. The measured spread is 34.6°F. The annual average is 63°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Heating and cooling both register in Allendale's normal, at 2,498 and 1,930 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 224-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.
These labels group NOAA 1991-2020 normals from Allendale'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 Allendale, the bands are descriptive ranges rather than an official NOAA classification or a forecast.
