From spring bud break until the start of fall foliage, Vermont’s Green Mountains hold true to their name. Lush with vegetation, the Vermont landscape relies on rain and snowfall (as well as sunlight) to power its growing season. But whether we revere our rain or wish for sunnier days, Vermont is getting wetter. Average annual precipitation, whether as rain or snow, has increased by 1.5 inches per decade since 1960.

Like the timing of Vermont’s hottest and coldest years, incidences of highest and lowest average annual precipitation establish some telling trends. Four of the five wettest years since 1960 all occurred after 1995. Four of the five driest occurred before 1981. Of course, weather is variable (the driest year in this data set was in 1995), but climate data reflects averages and suggests trends.
Using data averaged from the complete historical record of precipitation in Vermont, we can calculate that precipitation rates have increased approximately 0.7 of an inch per decade since 1895.
