Heating and cooling a home in Genoa
94% of the work is heating, so the furnace matters far more than the air conditioner. Months averaging under 55° run from October through April.
Degree days add up how far each day’s average falls below (heating) or rises above (cooling) 65° over a year. NOAA normals at Minden, NV.

| Town | Jan. low | July high | Precip. | Snow |
|---|---|---|---|---|
| Genoa, NV | 23° | 90° | 11" | 22" |
| Twin Falls, ID | 22° | 90° | 10" | 24" |
| Bluffdale, UT | 21° | 92° | 13" | 26" |
| Terrace Heights, WA | 25° | 89° | 9" | 20" |
| Snowflake, AZ | 20° | 90° | 10" | 13" |
Temperatures and rain come from NOAA’s 5 km grid, so each town gets its own value. Snow and frost-free days come from the nearest weather station, so neighbors often share them.
Warmer than it used to be
The last 30 years in Genoa averaged 1.2° warmer than the 1900s. The biggest change is in January (+2.3°).
A smaller shift than in 63% of U.S. towns.
Change by month
The two periods overlap (1991–2000 is in both), which makes the gap a little smaller than it would be between separate periods.
How Genoa compares
Against 12,954 U.S. towns of 2,500 or more (one per 5 km climate cell), with Genoa’s place among Nevada’s.
