What a year in St. Vincent feels like
Typical highs and lows by season and by month, from NOAA’s 30-year normals.
About 137 frost-free days a year

Heating and cooling a home in St. Vincent
97% of the work is heating, so the furnace matters far more than the air conditioner. Months averaging under 55° run from October through May.
Degree days add up how far each day’s average falls below (heating) or rises above (cooling) 65° over a year. NOAA normals at Pembina, ND.
Living with St. Vincent’s climate
What the numbers mean for a garden, a free afternoon and a bad-weather day.
137 frost-free days in zone 3b. The last frost comes by May 16 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 29.
Months with highs of 62–84° and lows of 40° or more: May, June, July, August and September.

| Town | Jan. low | July high | Precip. | Snow |
|---|---|---|---|---|
| St. Vincent, MN | −4° | 80° | 22" | 39" |
| Jamestown, ND | 1° | 82° | 21" | 46" |

| Gunnison, CO | 0° | 82° | 12" | 50" |
| Kingsford, MI | 5° | 80° | 29" | 61" |
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 St. Vincent averaged 2.0° warmer than the 1900s. The biggest change is in January (+4.7°).
A bigger shift than in 88% 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 St. Vincent compares
Against 12,954 U.S. towns of 2,500 or more (one per 5 km climate cell), with St. Vincent’s place among Minnesota’s.
