Rain and snow in Miami
Miami gets 42 inches of rain and melted snow a year. June is the wettest month and February the driest. Rain or snow falls on about 117 days a year. Snow covers the ground about 12 days of the year.
About 192 frost-free days a year
In half of years the last 32° night comes by April 17 and the first one by October 26. That leaves about 192 frost-free days for gardens, longer than 66% of U.S. towns.
Heating and cooling a home in Miami
Engineers use “degree days” to estimate how hard a furnace or air conditioner works. In Miami, 82% of that work is heating and 18% 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.
