The year, day by day
Lamar Muni works both ends of the calendar. Normal highs climb to 96°F by July 13 and hold at or above 90°F on 82 dates, then normal lows drop to freezing or below on 162 dates, bottoming at 13°F around December 28.
When the heat sits
Normal highs reach 90°F from June 12 through September 1, covering 82 dates. The broader mild season, normal highs of 70°F or more, runs April 16 to October 19.
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 1, then returns to freezing around October 23, covering 162 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 28, when 31% of years recorded at least a hundredth of an inch. The driest is January 5 at 8%. Summed across the calendar, that is about 64 wet dates a year.
The widest day
October 16 carries the biggest normal gap between afternoon and dawn, 37°F between the normal high and the normal low.

Where Lamar Muni Stands Nationally
Day-to-night contrast is extreme by national standards — the widest normal daily swing reaches about 37°F, sharper than nine in ten ranked stations see.
Heat is a defining feature of the normals calendar — the normal daily high reaches 90°F on roughly 82 days a year, more than four out of five ranked stations record.
Lamar Muni earns 2 nationally notable standings (outer quintiles) against 6,860 NOAA 1991–2020 normals stations; only those extremes render.

Lamar Muni runs a summer-peaked wet season
54% of Lamar Muni'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 2.9", on a wide 48.2°F gap between its warmest and coldest month. 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, June, taking 54% of the annual total between them.
- Driest month: December at 0.1".
- Winter share: 4% 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 Lamar Muni's precipitation splits across the calendar
About 64 days a year record measurable precipitation here, carrying 13.4" between them, or roughly 0.21 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.

Scarce-water calendar
Where Lamar Muni's limited precipitation lands
heating led · dry · mid swing
Lamar Muni's energy balance leans toward cold weather: 5,284 annual heating degree days against 1,315 for cooling. Its 48.2°F seasonal range still makes the monthly rows more useful than the annual average alone.
Lamar Muni's frost-free season lasts about 158 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 Lamar Muni's middle-range seasonal profile. The measured spread is 48.2°F. The annual average is 54°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Lamar Muni's cold-season load does not imply a wet climate. Annual precipitation is 13.3 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.

Data Sources
Data source: NOAA U.S. Climate Normals v1.0.1 (1991-2020). All figures on this page are from Lamar Muni's primary station: LAMAR MUNI AP (USW00003013). 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 Lamar Muni; facility counts that depend on place identity are therefore an upper bound, not a municipal census.
On this page every temperature, precipitation, and derived score for Lamar Muni comes from its primary NOAA station record.
