The year, day by day
Summer here tops out rather than builds: the warmest normal high is 88°F around July 7, short of 90°F on every date, while 130 dates carry a normal low at or below freezing, the coldest 21°F near December 23.
The freezing stretch
The normal low stays at or below 32°F into March 17, then returns to freezing around November 9, covering 130 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 38% of years recorded at least a hundredth of an inch. The driest is January 17 at 12%. Summed across the calendar, that is about 73 wet dates a year.
The widest day
October 19 carries the biggest normal gap between afternoon and dawn, 29°F between the normal high and the normal low.

Trinidad runs a summer-peaked wet season
42% of Trinidad'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 2.6", on a 38.9°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: July, August, May, taking 43% of the annual total between them.
- Driest month: February at 0.5".
- Winter share: 10% 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 Trinidad's precipitation splits across the calendar
About 72 days a year record measurable precipitation here, carrying 14.9" 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.
Winter brings real snow to Trinidad
Trinidad averages 55.1 inches of snowfall a year, with March the snowiest month on the normals, spread across roughly 16 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.
- Annual snowfall: 55.1 inches of depth.
- Days recording measurable snow: about 16 a year.
- At a rough ten-to-one melt ratio, snow accounts for on the order of 37% of the year's precipitation.
NOAA 1991-2020 normals. The ten-to-one ratio is a convention, not a measurement: real ratios vary with temperature, so treat the share as an order of magnitude rather than an exact split.

Snow and freeze rhythm
When cold and snow define Trinidad
heating led · dry · mid swing
Trinidad's energy balance leans toward cold weather: 4,845 annual heating degree days against 849 for cooling. Its 38.9°F seasonal range still makes the monthly rows more useful than the annual average alone.
Trinidad's frost-free season lasts about 168 days, a middle-length window whose endpoints matter more than the annual average. It describes freeze probability, not year-specific planting conditions.
-
1. Trinidad coldest normal
December
The monthly mean of 35°F (2°C) sits near freezing, so cold nights and above-freezing afternoons share the same month.
-
2. Trinidad typical freeze period
January through December
The station reports average freezing days from January through December.
-
3. Trinidad snow peak
March
Trinidad averages 55.1 inches of snow a year, with March the snowiest month on the normals.
