“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 Alpine
Alpine gets 37 inches of rain and melted snow a year. October is the wettest month and February the driest. Rain or snow falls on about 152 days a year. Snow covers the ground about 73 days of the year.
About 157 frost-free days a year
In half of years the last 32° night comes by May 6 and the first one by October 10. That leaves about 157 frost-free days for gardens, shorter than 74% of U.S. towns.
Heating and cooling a home in Alpine
Engineers use “degree days” to estimate how hard a furnace or air conditioner works. In Alpine, 92% of that work is heating and 8% 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.
Alpine and its neighbors
Alpine borders 4 towns with climate data. January nights across them vary by 1.2°. Sparta has the coldest January nights (16°) and Plainfield the hottest July afternoons (83°). Alpine’s January low is 17° and its July high 83°.
Temperatures and rain come from NOAA’s 5 km grid, so each town gets its own value.

Snow, frost dates and day counts come from NOAA’s weather station at East Grand Rapids, MI (12 mi) away. Normals are 30-year averages, not a forecast.
