Rain and snow in Moroni
Moroni gets 12 inches of rain and melted snow a year. May is the wettest month and June the driest. Rain or snow falls on about 69 days a year.
About 119 frost-free days a year
In half of years the last 32° night comes by May 26 and the first one by September 25. That leaves about 119 frost-free days for gardens, shorter than 97% of U.S. towns.
Heating and cooling a home in Moroni
Engineers use “degree days” to estimate how hard a furnace or air conditioner works. In Moroni, 95% of that work is heating and 5% 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.

Temperatures and rainfall come from NOAA’s gridded climate normals for Moroni itself (about a 3-mile square). Snow, frost dates and day counts come from NOAA’s weather station at Ephraim, UT (12 mi, snow) and Moroni, UT (1 mi, frost, heat and degree days). Normals are 30-year averages, not a forecast.
