To show variation within the months and not just the monthly totals, we show the rainfall accumulated over a sliding 31-day period centered around each day of the year. Trinidad experiences some seasonal variation in monthly rainfall.
The rainy period of the year lasts for 7.1 months, from March 27 to November 1, with a sliding 31-day rainfall of at least 0.5 inches. The most rain falls during the 31 days centered around August 2, with an average total accumulation of 2.0 inches.
The rainless period of the year lasts for 4.8 months, from November 1 to March 27. The least rain falls around January 16, with an average total accumulation of 0.1 inches.
Average Monthly Rainfall
We report snowfall in liquid-equivalent terms. The actual depth of new snowfall is typically between 5 and 10 times the liquid-equivalent amount, assuming the ground is frozen. Colder, drier snow tends to be on the higher end of that range and warmer, wetter snow on the lower end.
As with rainfall, we consider the snowfall accumulated over a sliding 31-day period centered around each day of the year. Trinidad experiences some seasonal variation in monthly liquid-equivalent snowfall.
The snowy period of the year lasts for 6.3 months, from October 22 to May 1, with a sliding 31-day liquid-equivalent snowfall of at least 0.1 inches. The most snow falls during the 31 days centered around December 10, with an average total liquid-equivalent accumulation of 0.3 inches.
The snowless period of the year lasts for 5.7 months, from May 1 to October 22. The least snow falls around July 16, with an average total liquid-equivalent accumulation of 0.0 inches.

Sunrise & Sunset with Twilight and Daylight Saving Time
We base the humidity comfort level on the dew point, as it determines whether perspiration will evaporate from the skin, thereby cooling the body. Lower dew points feel drier and higher dew points feel more humid. Unlike temperature, which typically varies significantly between night and day, dew point tends to change more slowly, so while the temperature may drop at night, a muggy day is typically followed by a muggy night.
The perceived humidity level in Trinidad, as measured by the percentage of time in which the humidity comfort level is muggy, oppressive, or miserable, does not vary significantly over the course of the year, remaining a virtually constant 0% throughout.
Humidity Comfort Levels
This section discusses the wide-area hourly average wind vector (speed and direction) at 10 meters above the ground. The wind experienced at any given location is highly dependent on local topography and other factors, and instantaneous wind speed and direction vary more widely than hourly averages.
The average hourly wind speed in Trinidad experiences mild seasonal variation over the course of the year.
The windier part of the year lasts for 7.4 months, from October 30 to June 13, with average wind speeds of more than 5.1 miles per hour. The windiest day of the year is April 10, with an average hourly wind speed of 6.1 miles per hour.
The calmer time of year lasts for 4.5 months, from June 13 to October 30. The calmest day of the year is August 7, with an average hourly wind speed of 4.1 miles per hour.
Average Wind Speed
The predominant average hourly wind direction in Trinidad varies throughout the year.

This section discusses the total daily incident shortwave solar energy reaching the surface of the ground over a wide area, taking full account of seasonal variations in the length of the day, the elevation of the Sun above the horizon, and absorption by clouds and other atmospheric constituents. Shortwave radiation includes visible light and ultraviolet radiation.
The average daily incident shortwave solar energy experiences extreme seasonal variation over the course of the year.
The brighter period of the year lasts for 3.0 months, from April 24 to July 25, with an average daily incident shortwave energy per square meter above 7.0 kWh. The brightest day of the year is June 11, with an average of 8.1 kWh.

This report illustrates the typical weather in Trinidad, based on a statistical analysis of historical hourly weather reports and model reconstructions from January 1, 1980 to December 31, 2016.
Temperature and Dew Point
There are 3 weather stations near enough to contribute to our estimation of the temperature and dew point in Trinidad.
For each station, the records are corrected for the elevation difference between that station and Trinidad according to the International Standard Atmosphere , and by the relative change present in the MERRA-2 satellite-era reanalysis between the two locations.
The estimated value at Trinidad is computed as the weighted average of the individual contributions from each station, with weights proportional to the inverse of the distance between Trinidad and a given station.
The stations contributing to this reconstruction are: Perry Stokes Airport (72%, 18 kilometers, northeast); Raton Municipal Airport/Crews Field (23%, 48 kilometers, south); and La Veta Mountain, La Veta Pass (4.7%, 70 kilometers, northwest).
All data relating to the Sun's position (e.g., sunrise and sunset) are computed using astronomical formulas from the book, Astronomical Tables of the Sun, Moon and Planets , by Jean Meeus.
All other weather data, including cloud cover, precipitation, wind speed and direction, and solar flux, come from NASA's MERRA-2 Modern-Era Retrospective Analysis . This reanalysis combines a variety of wide-area measurements in a state-of-the-art global meteorological model to reconstruct the hourly history of weather throughout the world on a 50-kilometer grid.
Land Use data comes from the Global Land Cover SHARE database , published by the Food and Agriculture Organization of the United Nations.
