The year, day by day

Sanford Dam works both ends of the calendar. Normal highs climb to 97°F by July 17 and hold at or above 90°F on 92 dates, then normal lows drop to freezing or below on 127 dates, bottoming at 21°F around January 8.

When the heat sits

Normal highs reach 90°F from June 6 through September 5, covering 92 dates. The broader mild season, normal highs of 70°F or more, runs April 1 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 March 17, then returns to freezing around November 12, covering 127 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 August 6, when 26% of years recorded at least a hundredth of an inch. The driest is January 15 at 8%. Summed across the calendar, that is about 63 wet dates a year.

The widest day

March 26 carries the biggest normal gap between afternoon and dawn, 34°F between the normal high and the normal low.

Where Sanford Dam Stands Nationally

Heat is a defining feature of the normals calendar — the normal daily high reaches 90°F on roughly 92 days a year, more than four out of five ranked stations record.

Daily temperature swings run wider than most of the country, peaking near 34°F between the normal high and low.

Sanford Dam runs a summer-peaked wet season

43% of Sanford Dam's yearly precipitation falls in June, July and August alone, against the 25% an evenly spread year would give those three months. The wettest month is June at 3.0", on a 44.4°F seasonal spread. Warm-season convection and, across the Southwest, the North American monsoon produce this shape: rain arrives in short heavy bursts during the hottest part of the year rather than as long cool-season soaking.

Shares are computed from this station's own 1991-2020 monthly precipitation normals. A summer-peaked label means the June-August share reaches 35%; it describes timing across an average year, not any single season, and says nothing about how heavy an individual storm can be.

How Sanford Dam's precipitation splits across the calendar

About 63 days a year record measurable precipitation here, carrying 19.2" between them, or roughly 0.31 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.

Data-derived climate profile

How Sanford Dam's climate pattern fits together

heating led · dry · mid swing

Sanford Dam's energy balance leans toward cold weather: 4,149 annual heating degree days against 1,739 for cooling. Its 44.4°F seasonal range still makes the monthly rows more useful than the annual average alone.

Sanford Dam's frost-free season lasts about 188 days, a middle-length window whose endpoints matter more than the annual average. It describes freeze probability, not year-specific planting conditions.

July and January mark the typical warm and cold ends of the calendar in Sanford Dam's middle-range seasonal profile. The measured spread is 44.4°F. The annual average is 58°F. Neither the annual mean nor one extreme month represents the full calendar on its own.

Sanford Dam's cold-season load does not imply a wet climate. Annual precipitation is 19.2 inches, which places the station in PlainClimate's dry range. Snowfall is not added to the interpretation because its annual value is missing. The snowfall and rainfall fields should be read separately rather than inferred from temperature.

These labels group NOAA 1991-2020 normals from Sanford Dam'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 Sanford Dam, not an official NOAA class or a year-ahead forecast.

Questions about Sanford Dam's climate

How much rain does Sanford Dam get?
Sanford Dam receives 19.2 inches of precipitation. Based on NOAA 30-year climate normals (1991-2020).
How many days above 90°F does Sanford Dam get?
Sanford Dam averages about 94 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 Sanford Dam?
Sanford Dam has 4,149 heating degree days and 1,739 cooling degree days annually, a heating-dominated climate. 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 Sanford Dam's primary station: SANFORD DAM (USC00418040). 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 Sanford Dam; facility counts that depend on place identity are therefore an upper bound, not a municipal census.
