Heating and cooling a home in Clearwater
95% 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 St Cloud Rgnl Airport.
Living with Clearwater’s climate
What the numbers mean for a garden, a free afternoon and a bad-weather day.
144 frost-free days in zone 4b. The last frost comes by May 7 in half of years, so many gardeners wait a week or two past that to set out tomatoes. The first fall frost comes by Sep 30.
Months with highs of 62–84° and lows of 40° or more: May, June, July, August and September. 0.7 miles of trails are waiting.

| Town | Jan. low | July high | Precip. | Snow |
|---|---|---|---|---|
| Clearwater, MN | 4° | 82° | 30" | 48" |
| Plover, WI | 7° | 81° | 34" | 49" |

| Spencer, IA | 7° | 84° | 31" | 43" |
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 Clearwater averaged 1.6° warmer than the 1900s. The biggest change is in January (+3.6°).
A bigger shift than in 68% 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 Clearwater compares
