“Wet days” have at least 0.01" of rain or melted snow. “Snow on ground” counts days with 1" or more. The 30-year range is the coldest and warmest that month’s average temperature got between 1991 and 2020.
Rain and snow in Trinidad
Trinidad gets 14 inches of rain and melted snow a year. July is the wettest month and January the driest. Rain or snow falls on about 72 days a year. Snow covers the ground about 25 days of the year.
About 167 frost-free days a year
In half of years the last 32° night comes by April 30 and the first one by October 15. That leaves about 167 frost-free days for gardens, shorter than 64% of U.S. towns.
Heating and cooling a home in Trinidad
Engineers use “degree days” to estimate how hard a furnace or air conditioner works. In Trinidad, 85% of that work is heating and 15% is cooling, so the furnace matters far more than the air conditioner.
Degree days measure how far each day’s average temperature falls below or rises above 65°, added up over a year. Source: NOAA station normals.
