“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 Lynn
Lynn gets 28 inches of rain and melted snow a year. May is the wettest month and January the driest. Rain or snow falls on about 70 days a year. Snow covers the ground about 28 days of the year.
About 181 frost-free days a year
In half of years the last 32° night comes by April 19 and the first one by October 20. That leaves about 181 frost-free days for gardens, longer than 54% of U.S. towns.
Heating and cooling a home in Lynn
Engineers use “degree days” to estimate how hard a furnace or air conditioner works. In Lynn, 84% of that work is heating and 16% 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.
