The year, day by day
The year in Coronado Nmem runs from a mild 33°F around January 1 to 93°F at the peak near June 19, and the normal low never reaches freezing on any date in the record.
When the heat sits
Normal highs reach 90°F from June 5 through July 10, covering 36 dates. The broader mild season, normal highs of 70°F or more, runs March 22 to November 6.
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 January 1.
Where the wet dates fall
The likeliest wet date is July 31, when 50% of years recorded at least a hundredth of an inch. The driest is April 29 at 4%. Summed across the calendar, that is about 70 wet dates a year.
The widest day
June 6 carries the biggest normal gap between afternoon and dawn, 32°F between the normal high and the normal low.

Coronado Nmem runs a summer-peaked wet season
49% of Coronado Nmem'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 August at 4.8", on a 30°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: August, July, September, taking 55% of the annual total between them.
- Driest month: May at 0.2".
- Winter share: 24% 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 Coronado Nmem's precipitation splits across the calendar
About 70 days a year record measurable precipitation here, carrying 20.8" 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 Coronado Nmem, but rarely amounts to much
The normals record 3.2 inches of snow a year here, most likely in December. 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; about 2 days a year record any measurable snow at all.
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 Coronado Nmem's climate pattern fits together
heating led · moderate · low swing
Heating is the larger measured load in Coronado Nmem, at 2,660 degree days versus 1,323 for cooling. Unlike a strongly continental record, however, its 30.0°F month-to-month range is compact; persistent cool-season demand matters more than a dramatic summer-to-winter reversal.
Coronado Nmem's frost-free season lasts about 216 days, a middle-length window whose endpoints matter more than the annual average. It describes freeze probability, not year-specific planting conditions.
Temperature varies within a narrow 30.0°F band across the normal year. June and January mark the typical warm and cold ends of the calendar. The annual average is 61°F. Monthly rows still matter, but they refine a steady profile rather than reveal two climatic extremes.
Coronado Nmem's 20.8 inches of annual precipitation falls in PlainClimate's middle band, so “wet” or “dry” is not the leading description. Annual snowfall totals 3.2 inches. Temperature balance and the calendar distribution carry more information than the annual moisture label alone.
These labels group NOAA 1991-2020 normals from Coronado Nmem'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 Coronado Nmem, not an official NOAA class or a year-ahead forecast.

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