The year, day by day

The year in Granger Dam runs from a mild 36°F around January 9 to 98°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 June 2 through September 19, covering 110 dates. The broader mild season, normal highs of 70°F or more, runs March 11 to November 18.

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 36°F around January 9.

Where the wet dates fall

The likeliest wet date is February 21, when 27% of years recorded at least a hundredth of an inch. The driest is July 28 at 13%. Summed across the calendar, that is about 82 wet dates a year.

The widest day

October 12 carries the biggest normal gap between afternoon and dawn, 26°F between the normal high and the normal low.

Where Granger Dam Stands Nationally

Summers here run among the most heat-heavy normals calendars in the country: on about 110 days a year the normal daily high itself reaches 90°F — a count fewer than one station in ten exceeds.

Granger Dam earns one nationally notable standing (outer quintile) against 6,860 NOAA 1991–2020 normals stations, middle-of-the-pack metrics stay silent here.

Granger Dam spreads its precipitation across the year

Neither half of the year dominates here: June through August take 23% of the annual total and December through February 22%, with neither reaching the 35% that would mark a distinct wet season. Granger Dam has no dry season to plan around, though it does carry a 35.6°F seasonal spread.

The gap between the wettest and driest month still matters: May averages 5.0" and July 2.0". The three wettest months together take 33% 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 Granger Dam, it arrives in quantity

35.1" of precipitation falls across only about 83 wet days here, averaging 0.43 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

Average depth per wet day

Fewest wet days
July, about 5

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.

Granger Dam's record shows no measurable snowfall

This station measured snowfall across the 1991-2020 period and recorded none: the annual normal is 0.0 inches. That is a measured zero rather than missing data, which is a meaningful distinction here , most stations in the database simply do not report snow at all, and those pages say nothing about it.

A thirty-year normal of zero describes the typical year at this station. It is not a claim that snow has never fallen in the area.

Data-derived climate profile

How Granger Dam's climate pattern fits together

mixed demand · moderate · mid swing

August and January mark the typical warm and cold ends of the calendar in Granger Dam's middle-range seasonal profile. The measured spread is 35.6°F. The annual average is 68°F. Neither the annual mean nor one extreme month represents the full calendar on its own.

Heating and cooling both register in Granger Dam's normal, at 1,860 and 2,802 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.

The frost-free window extends for about 262 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.

Granger Dam's 35.1 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.

These labels group NOAA 1991-2020 normals from Granger Dam'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 Granger Dam, the bands are descriptive ranges rather than an official NOAA classification or a forecast.

Questions about Granger Dam's climate

How much rain does Granger Dam get?
Granger Dam receives 35.1 inches of precipitation. Based on NOAA 30-year climate normals (1991-2020).
How many days above 90°F does Granger Dam get?
Granger Dam averages about 111 days a year at or above 90°F, concentrated in August 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 Granger Dam?
Granger Dam has 1,860 heating degree days and 2,802 cooling degree days annually, a fairly balanced heating/cooling split. Degree-day definitions: reading weather data.

Data Sources

Data source: NOAA U.S. Climate Normals v1.0.1 (1991-2020). All figures on this page are from Granger Dam's primary station: GRANGER DAM (USC00413686). 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 Granger Dam; facility counts that depend on place identity are therefore an upper bound, not a municipal census.
