The year, day by day
Aberdeen works both ends of the calendar. Normal highs climb to 91°F by July 17 and hold at or above 90°F on 46 dates, then normal lows drop to freezing or below on 48 dates, bottoming at 30°F around January 18.
When the heat sits
Normal highs reach 90°F from July 4 through August 18, covering 46 dates. The broader mild season, normal highs of 70°F or more, runs April 3 to October 29.
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 8, then returns to freezing around December 23, covering 48 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 January 17, when 34% of years recorded at least a hundredth of an inch. The driest is September 10 at 20%. Summed across the calendar, that is about 103 wet dates a year.
The widest day
October 28 carries the biggest normal gap between afternoon and dawn, 26°F between the normal high and the normal low.

Aberdeen 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 30%, with neither reaching the 35% that would mark a distinct wet season. Aberdeen has no dry season to plan around, though it does carry a 38.3°F seasonal spread.
The gap between the wettest and driest month still matters: December averages 5.8" and October 3.3". The three wettest months together take 31% 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 Aberdeen, it arrives in quantity
54.3" of precipitation falls across only about 103 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.
- Days with measurable precipitation
- about 103 a year, 28% of all days
- Average depth per wet day
- 0.53 inches
- Most wet days
- January, about 10
- Fewest wet days
- September, about 6
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 Aberdeen, but rarely amounts to much
The normals record 0.1 inches of snow a year here, most likely in January. 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 Aberdeen's climate pattern fits together
mixed demand · wet · mid swing
Water is prominent even though neither heating nor cooling wholly defines the record. Aberdeen averages 54.3 inches of precipitation a year. Recorded annual snowfall is negligible. 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 Aberdeen's middle-range seasonal profile. The measured spread is 38.3°F. The annual average is 61°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Heating and cooling both register in Aberdeen's normal, at 3,101 and 1,803 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 221-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 Aberdeen'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 Aberdeen, the bands are descriptive ranges rather than an official NOAA classification or a forecast.
