The year, day by day

Summer here tops out rather than builds: the warmest normal high is 87°F around July 11, short of 90°F on every date, while 187 dates carry a normal low at or below freezing, the coldest 14°F near December 25.

The freezing stretch

The normal low stays at or below 32°F into April 22, then returns to freezing around October 19, covering 187 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 30, when 41% of years recorded at least a hundredth of an inch. The driest is January 1 at 13%. Summed across the calendar, that is about 78 wet dates a year.

The widest day

October 6 carries the biggest normal gap between afternoon and dawn, 35°F between the normal high and the normal low.

Where Trinidad Lake Stands Nationally

Freezing is routine here by normals standards — the normal low reaches 32°F or colder on about 187 nights a year, more than most ranked stations.

Daily temperature swings run wider than most of the country, peaking near 35°F between the normal high and low.

Trinidad Lake runs a summer-peaked wet season

42% of Trinidad Lake'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 3.0", on a 39.2°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.

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 Trinidad Lake's precipitation splits across the calendar

About 78 days a year record measurable precipitation here, carrying 17.2" between them, or roughly 0.22 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 Trinidad Lake

Trinidad Lake averages 48.1 inches of snowfall a year, with January the snowiest month on the normals, spread across roughly 13 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.

Snow and freeze rhythm

When cold and snow define Trinidad Lake

heating led · dry · mid swing

Trinidad Lake's energy balance leans toward cold weather: 5,958 annual heating degree days against 446 for cooling. Its 39.2°F seasonal range still makes the monthly rows more useful than the annual average alone.

Only about 146 days are frost-free in a normal year. That short interval is consistent with the cold-season signal, but the measure does not predict the exact first or last freeze in any one year.

  1. 1. Trinidad Lake coldest normal

    January

    The monthly mean of 31°F (0°C) sits near freezing, so cold nights and above-freezing afternoons share the same month.

  2. 2. Trinidad Lake typical freeze period

    January through December

    The station reports average freezing days from January through December.

  3. 3. Trinidad Lake snow peak

    January

    Trinidad Lake averages 48.1 inches of snow a year, with January the snowiest month on the normals.

Questions about Trinidad Lake's climate

How much snow does Trinidad Lake get?
Trinidad Lake averages 48.1 inches of snow a year, most of it in January, within 17.2 inches of total precipitation. Snowfall is depth on the ground; the precipitation total counts its liquid equivalent, so the two are not additive.
How cold does Trinidad Lake get in winter?
Trinidad Lake records about 179 days a year with a low at or below freezing, with January the coldest month on the normals, and an annual average daily low of 34°F.
How much energy does heating and cooling require in Trinidad Lake?
Trinidad Lake has 5,958 heating degree days and 446 cooling degree days annually, a heating-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 Trinidad Lake's primary station: TRINIDAD LAKE (USC00058436). 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 Trinidad Lake; facility counts that depend on place identity are therefore an upper bound, not a municipal census.
