“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 Welsh
Welsh gets 62 inches of rain and melted snow a year. June is the wettest month and March the driest. Rain or snow falls on about 124 days a year.
About 292 frost-free days a year
In half of years the last 32° night comes by February 19 and the first one by December 4. That leaves about 292 frost-free days for gardens, longer than 94% of U.S. towns.
Heating and cooling a home in Welsh
Engineers use “degree days” to estimate how hard a furnace or air conditioner works. In Welsh, 38% of that work is heating and 62% is cooling, so air conditioning is the bigger bill.
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.

Temperatures and rainfall come from NOAA’s gridded climate normals for Welsh itself (about a 3-mile square). Snow, frost dates and day counts come from NOAA’s weather station at Jennings, LA (9 mi) away. Normals are 30-year averages, not a forecast.
