Rain and snow in New Hope
New Hope gets 21 inches of rain and melted snow a year. June is the wettest month and January the driest. Rain or snow falls on about 88 days a year.
About 137 frost-free days a year
In half of years the last 32° night comes by May 11 and the first one by September 27. That leaves about 137 frost-free days for gardens, shorter than 91% of U.S. towns.
Heating and cooling a home in New Hope
Engineers use “degree days” to estimate how hard a furnace or air conditioner works. In New Hope, 94% of that work is heating and 6% 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.
