Regional context

St. Paul's climate, from NOAA NCEI 1991-2020 station normals, pairs 14°F Januarys with 74°F Julys — a 59°F swing. About 33.1 inches of precipitation falls over roughly 173 days a year.

Precipitation in St. Paul runs summer-dominant: June averages 4.4 inches across 16.8 days of warm-season storms, while January drops to 1.1 inches over 13.5 rainy days of drier cool air. That summer-storm rhythm groups St. Paul with places like Lilydale, MN, West St. Paul, MN and Falcon Heights, MN.

The cool-season window in St. Paul starts at late-May, when nights stop freezing — think kale, peas, spinach, and parsnips. Hold St. Paul's tender crops — tomatoes, peppers, basil — until 10-14 days past St. Paul's last frost. It shuts near early-October, when freezes return to St. Paul and tender plants need cover. Within St. Paul, cold-air pooling chills low spots by 5-10°F, shifting St. Paul's local frost dates.

Similar climates: Lilydale, MN, West St. Paul, MN, Falcon Heights, MN, Maplewood, MN, Mendota Heights, MN.
