The year, day by day

The year in Marlin runs from a mild 33°F around January 9 to 96°F at the peak near August 4, and the normal low never reaches freezing on any date in the record.

When the heat sits

Normal highs reach 90°F from June 11 through September 15, covering 97 dates. The broader mild season, normal highs of 70°F or more, runs March 19 to November 13.

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 9.

Where the wet dates fall

The likeliest wet date is March 1, when 26% of years recorded at least a hundredth of an inch. The driest is August 1 at 10%. Summed across the calendar, that is about 75 wet dates a year.

The widest day

November 13 carries the biggest normal gap between afternoon and dawn, 28°F between the normal high and the normal low.

Where Marlin Stands Nationally

Summers here run among the most heat-heavy normals calendars in the country: on about 97 days a year the normal daily high itself reaches 90°F — a count fewer than one station in ten exceeds.

Marlin earns one nationally notable standing (outer quintile) against 6,860 NOAA 1991–2020 normals stations, middle-of-the-pack metrics stay silent here.

Marlin spreads its precipitation across the year

Neither half of the year dominates here: June through August take 18% of the annual total and December through February 25%, with neither reaching the 35% that would mark a distinct wet season. Marlin has no dry season to plan around, though it does carry a 36.8°F seasonal spread.

The gap between the wettest and driest month still matters: May averages 5.0" and July 1.8". The three wettest months together take 33% 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.

When it rains in Marlin, it arrives in quantity

39.1" of precipitation falls across only about 74 wet days here, averaging 0.53 inches each. Fewer days carry more water: the year's total is delivered in comparatively heavy events rather than persistent damp.

Data-derived climate profile

How Marlin's climate pattern fits together

mixed demand · moderate · mid swing

August and January mark the typical warm and cold ends of the calendar in Marlin's middle-range seasonal profile. The measured spread is 36.8°F. The annual average is 65°F. Neither the annual mean nor one extreme month represents the full calendar on its own.

Heating and cooling both register in Marlin's normal, at 2,295 and 2,429 degree days respectively. Neither total exceeds the other by more than two to one, so the record is better read as a mixed-demand calendar than as heating-led or cooling-led.

A roughly 233-day frost-free season sits inside this mixed heating-and-cooling profile. Start and end dates matter because both sides of the thermostat register during a normal year.

Marlin's 39.1 inches of annual precipitation falls in PlainClimate's middle band, so “wet” or “dry” is not the leading description. Snowfall is not added to the interpretation because its annual value is missing. Temperature balance and the calendar distribution carry more information than the annual moisture label alone.

These labels group NOAA 1991-2020 normals from Marlin's primary station, where heating and cooling demand are close enough that neither season sets the character on its own. On a balanced station like Marlin, the bands are descriptive ranges rather than an official NOAA classification or a forecast.

Questions about Marlin's climate

How much rain does Marlin get?
Marlin receives 39.1 inches of precipitation. Based on NOAA 30-year climate normals (1991-2020).
How many days above 90°F does Marlin get?
Marlin averages about 102 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 Marlin?
Marlin has 2,295 heating degree days and 2,429 cooling degree days annually, a fairly balanced heating/cooling split. Degree-day definitions: reading weather data.
