The year, day by day
The year in Amistad Dam runs from a mild 39°F around January 1 to 98°F at the peak near August 3, and the normal low never reaches freezing on any date in the record.
When the heat sits
Normal highs reach 90°F from May 20 through September 16, covering 120 dates. The broader mild season, normal highs of 70°F or more, runs February 24 to November 17.
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 39°F around January 1.
Where the wet dates fall
The likeliest wet date is May 18, when 22% of years recorded at least a hundredth of an inch. The driest is July 30 at 12%. Summed across the calendar, that is about 65 wet dates a year.
The widest day
April 3 carries the biggest normal gap between afternoon and dawn, 25°F between the normal high and the normal low.

Where Amistad Dam Stands Nationally
Summers here run among the most heat-heavy normals calendars in the country: on about 120 days a year the normal daily high itself reaches 90°F — a count fewer than one station in ten exceeds.

Amistad Dam 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 10%, with neither reaching the 35% that would mark a distinct wet season. Amistad Dam has no dry season to plan around, though it does carry a 34.4°F seasonal spread.
The gap between the wettest and driest month still matters: September averages 3.2" and February 0.7". The three wettest months together take 43% 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.
How Amistad Dam's precipitation splits across the calendar
About 65 days a year record measurable precipitation here, carrying 19.4" between them, or roughly 0.30 inches on a typical wet day. That sits in the middle band: neither the many-light-days pattern of the Pacific Northwest and the Great Lakes, nor the few-heavy-events pattern of the Gulf and the desert Southwest.
A wet day is one recording at least 0.01 inches. These are 1991-2020 normals: they describe an average year and say nothing about the heaviest single storm on record.
Snow reaches Amistad Dam, 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.
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 Amistad Dam's climate pattern fits together
cooling led · dry · mid swing
Air-conditioning demand is the clearest thermal signal here. Amistad Dam accumulates 3,176 cooling degree days, more than twice its 1,493 heating total; the monthly table shows when that imbalance builds rather than treating it as a year-round condition.
Heat demand sits beside limited local precipitation: Amistad Dam receives 19.4 inches in a normal year, inside PlainClimate's dry range. Recorded annual snowfall is negligible. Month-level precipitation is the useful check on when that small annual total arrives.
August and January mark the typical warm and cold ends of the calendar in Amistad Dam's middle-range seasonal profile. The measured spread is 34.4°F. The annual average is 70°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Amistad Dam has a long frost-free window of roughly 295 days, but the dry annual profile is a separate constraint. Growing-season length says when freezes are unlikely, not whether rainfall is sufficient.
These labels group NOAA 1991-2020 normals from Amistad Dam's primary station, so the summer figures are a thirty-year average rather than a ceiling: individual years have run hotter and will again. For Amistad Dam that means a descriptive range only — not an official NOAA classification and not a prediction for next summer.

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 Amistad Dam; facility counts that depend on place identity are therefore an upper bound, not a municipal census.
