The year, day by day

The year in Dobbins runs from a mild 33°F around December 19 to 95°F at the peak near July 23, and the normal low never reaches freezing on any date in the record.

When the heat sits

Normal highs reach 90°F from June 27 through September 13, covering 79 dates. The broader mild season, normal highs of 70°F or more, runs April 24 to November 2.

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 December 19.

Where the wet dates fall

The likeliest wet date is January 22, when 39% of years recorded at least a hundredth of an inch. The driest is July 21 at 1%. Summed across the calendar, that is about 71 wet dates a year.

The widest day

August 30 carries the biggest normal gap between afternoon and dawn, 39°F between the normal high and the normal low.

Where Dobbins Stands Nationally

Day-to-night contrast is extreme by national standards — the widest normal daily swing reaches about 39°F, sharper than nine in ten ranked stations see.

Heat is a defining feature of the normals calendar — the normal daily high reaches 90°F on roughly 79 days a year, more than four out of five ranked stations record.

Dobbins earns 2 nationally notable standings (outer quintiles) against 6,860 NOAA 1991–2020 normals stations; only those extremes render.

Dobbins's wet season runs through the cold months

December, January and February carry 51% of the year's precipitation here, while June through August contribute 2%. That is the cool-season-dominant pattern of the West Coast and the higher inland West, where storm tracks swing south in winter and summer turns dry; the thermometer meanwhile shows a 30.6°F seasonal spread.

Shares are computed from this station's own 1991-2020 monthly precipitation normals. A cool-season label means the December-February share reaches 35%. Where snow falls, the monthly figures above report liquid-equivalent precipitation, so a wet winter month is not necessarily a rainy one.

When it rains in Dobbins, it arrives in quantity

46.3" of precipitation falls across only about 70 wet days here, averaging 0.66 inches each. Fewer days carry more water: the year's total is delivered in comparatively heavy events rather than persistent damp.

Data-derived climate profile

How Dobbins's climate pattern fits together

heating led · wet · mid swing

Dobbins's energy balance leans toward cold weather: 3,283 annual heating degree days against 1,015 for cooling. Its 30.6°F seasonal range still makes the monthly rows more useful than the annual average alone.

Dobbins's frost-free season lasts about 230 days, a middle-length window whose endpoints matter more than the annual average. It describes freeze probability, not year-specific planting conditions.

July and December mark the typical warm and cold ends of the calendar in Dobbins's middle-range seasonal profile. The measured spread is 30.6°F. The annual average is 59°F. Neither the annual mean nor one extreme month represents the full calendar on its own.

Alongside its heating load, Dobbins carries 46.3 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 Dobbins'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 Dobbins, not an official NOAA class or a year-ahead forecast.

Questions about Dobbins's climate

How much rain does Dobbins get?
Dobbins receives 46.3 inches of precipitation. Based on NOAA 30-year climate normals (1991-2020).
How many days above 90°F does Dobbins get?
Dobbins averages about 79 days a year at or above 90°F, concentrated in July and the months either side of it. That is a count of days reaching the threshold, not a measure of how far above it they go.
How much energy does heating and cooling require in Dobbins?
Dobbins has 3,283 heating degree days and 1,015 cooling degree days annually, a heating-dominated climate. Degree-day definitions: reading weather data.
