The year, day by day
Black Rvr Pumps works both ends of the calendar. Normal highs climb to 90°F by June 28 and hold at or above 90°F on 3 dates, then normal lows drop to freezing or below on 178 dates, bottoming at 19°F around December 21.
When the heat sits
Normal highs reach 90°F from June 28 through June 30, covering 3 dates. The broader mild season, normal highs of 70°F or more, runs April 26 to October 23.
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 April 23, then returns to freezing around October 29, covering 178 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 July 31, when 43% of years recorded at least a hundredth of an inch. The driest is May 30 at 9%. Summed across the calendar, that is about 72 wet dates a year.
The widest day
June 8 carries the biggest normal gap between afternoon and dawn, 40°F between the normal high and the normal low.

Where Black Rvr Pumps Stands Nationally
Day-to-night contrast is extreme by national standards — the widest normal daily swing reaches about 40°F, sharper than nine in ten ranked stations see.

Black Rvr Pumps runs a summer-peaked wet season
37% of Black Rvr Pumps'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 July at 3.3", on a 36.1°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.
- Wettest three months: July, August, September, taking 46% of the annual total between them.
- Driest month: April at 0.5".
- Winter share: 27% falls in December, January and February.
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 Black Rvr Pumps's precipitation splits across the calendar
About 72 days a year record measurable precipitation here, carrying 18.7" between them, or roughly 0.26 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.
Winter brings real snow to Black Rvr Pumps
Black Rvr Pumps averages 13.7 inches of snowfall a year, with February the snowiest month on the normals, spread across roughly 5 days that record measurable snow. That is depth accumulating on the ground, which is why it can exceed the annual precipitation figure: precipitation counts the liquid the snow melts down to, and fresh snow is mostly air.
- Annual snowfall: 13.7 inches of depth.
- Days recording measurable snow: about 5 a year.
- At a rough ten-to-one melt ratio, snow accounts for on the order of 7% of the year's precipitation.
NOAA 1991-2020 normals. The ten-to-one ratio is a convention, not a measurement: real ratios vary with temperature, so treat the share as an order of magnitude rather than an exact split.

Snow and freeze rhythm
When cold and snow define Black Rvr Pumps
heating led · dry · mid swing
Black Rvr Pumps's energy balance leans toward cold weather: 4,976 annual heating degree days against 587 for cooling. Its 36.1°F seasonal range still makes the monthly rows more useful than the annual average alone.
Black Rvr Pumps's frost-free season lasts about 150 days, a middle-length window whose endpoints matter more than the annual average. It describes freeze probability, not year-specific planting conditions.

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 Black Rvr Pumps; facility counts that depend on place identity are therefore an upper bound, not a municipal census.
