El Centro Naf's normals sit in a dry climate class: BWh

Annual precipitation falls well below the aridity threshold for this temperature regime, so the normals classify as hot desert (BWh). Class BWh is the Peel et al. (2007) label for this station's monthly mean temperature and precipitation normals: dry (arid or semi-arid), specifically hot desert.

The year, day by day

The year in El Centro Naf runs from a mild 40°F around December 20 to 108°F at the peak near July 10, and the normal low never reaches freezing on any date in the record.

When the heat sits

Normal highs reach 90°F from April 30 through October 18, covering 172 dates. The broader mild season, normal highs of 70°F or more, runs January 11 to December 5.

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 40°F around December 20.

The widest day

June 10 carries the biggest normal gap between afternoon and dawn, 35°F between the normal high and the normal low.

Where El Centro Naf Stands Nationally

Summers here run among the most heat-heavy normals calendars in the country: on about 172 days a year the normal daily high itself reaches 90°F — a count fewer than one station in ten exceeds.

Aridity defines the water calendar: about 5 inches in a normal year lands this among the driest tenth of ranked stations.

El Centro Naf earns 2 nationally notable standings (outer quintiles) against 6,860 NOAA 1991–2020 normals stations; only those extremes render.

El Centro Naf's wet season runs through the cold months

December, January and February carry 46% of the year's precipitation here, while June through August contribute 19%. That is the cool-season-dominant pattern of the West Coast and the higher inland West, where storm tracks swing south in winter and summer turns dry; the thermometer meanwhile shows a 37.9°F seasonal spread.

Shares are computed from this station's own 1991-2020 monthly precipitation normals. A cool-season label means the December-February share reaches 35%. Where snow falls, the monthly figures above report liquid-equivalent precipitation, so a wet winter month is not necessarily a rainy one.

Scarce-water calendar

Where El Centro Naf's limited precipitation lands

cooling led · dry · mid swing

Air-conditioning demand is the clearest thermal signal here. El Centro Naf accumulates 4,103 cooling degree days, more than twice its 931 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: El Centro Naf receives 5.1 inches in a normal year, inside PlainClimate's dry range. Snowfall is not added to the interpretation because its annual value is missing. Month-level precipitation is the useful check on when that small annual total arrives.

August and December mark the typical warm and cold ends of the calendar in El Centro Naf's middle-range seasonal profile. The measured spread is 37.9°F. The annual average is 74°F. Neither the annual mean nor one extreme month represents the full calendar on its own.

With about 349 frost-free days, the calendar is constrained more by sustained heat than by freeze timing. This does not measure crop suitability or soil moisture; it only reports the NOAA-derived frost-free window for El Centro Naf.

Questions about El Centro Naf's climate

How dry is El Centro Naf?
El Centro Naf receives 5.1 inches of precipitation a year. For reference, the contiguous United States averages near 30 inches. Based on NOAA 30-year climate normals (1991-2020).
How many days above 90°F does El Centro Naf get?
El Centro Naf averages about 179 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 El Centro Naf?
El Centro Naf has 931 heating degree days and 4,103 cooling degree days annually, a cooling-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 El Centro Naf's primary station: EL CENTRO NAF (USW00023199). 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 El Centro Naf; facility counts that depend on place identity are therefore an upper bound, not a municipal census.
