When is the best weather to visit St. Cloud?

Normal highs sit between 65°F and 85°F in May, June, July, August and September. Of those, August has the fewest days with rain (9).

That is a measurement, not a recommendation: it counts the months whose normal afternoon high sits between 65°F and 85°F, where a light layer is enough by day.

When is the last frost in St. Cloud?

In St. Cloud, the last spring frost (32°F) comes after May 7 in half of years and after May 23 in one year in ten; the first autumn frost comes before September 30 in half of years and before September 16 in one year in ten.

First autumn frost, half of years before
September 301 year in 10 before September 16; 9 in 10 before October 12

NOAA puts the median frost-free season at 144 days, and the season without a hard freeze (28°F) at 164 days.

A hard freeze (28°F) comes after April 27 in half of springs and before October 8 in half of autumns.

The USDA's 2023 Plant Hardiness Zone Map puts St. Cloud in zone 4b across its 3 ZIP code areas (4b in 56301, the largest). By the map's own method, the average of each year's coldest night over 1991-2020, St. Cloud's NOAA station is in zone 4a: the coldest night of a typical year reaches −25°F (30 complete years); the map interpolates between stations and terrain, so the station and the ZIP area can differ by half a zone.

A 10% date means one year in ten has a frost after it in spring or before it in autumn.

What hardiness zone is each St. Cloud ZIP code in?

The USDA's 2023 map gives each ZIP code area one zone. St. Cloud's 3 ZIP code areas are all in zone 4b. Each ZIP's frost dates are in the frost tool.

How sunny is St. Cloud?

Over a year 74% of the sunlight that would reach the ground under clear skies gets through the clouds in the area around St. Cloud, 3.9 kWh per square metre a day. July is the sunniest month (82%) and December the cloudiest (61%). Among the 459 U.S. places of 50,000 or more, that ranks tied 330th (with 21 others) in sunshine.

How much heating and cooling does St. Cloud need?

A normal year in St. Cloud brings 8,490 heating degree days, 58% more than the median U.S. place (5,373), and 468 cooling degree days, 48% fewer than the median (908). Seven months need 300 or more heating degree days, a monthly mean of about 55°F or colder. For gardens and crops, NOAA counts 2,311 growing degree days a year above 50°F.

Has St. Cloud been warmer than normal lately?

2025 averaged 44.8°F, 1.9°F above the 1991-2020 normal of 42.9°F. 4 of the 5 complete years since 2021 ran warmer than the normal.

How does St. Cloud's climate compare?

St. Cloud is warmer than 58 of the other 128 places with their own NOAA record in Minnesota, and wetter than 42. Across the 7,247 U.S. stations with normals, its annual mean of 42.9°F is warmer than 12%.

In the Köppen classification computed from these normals, St. Cloud is Dfb: continental, no dry season, warm summer. What the classes mean.

Which places near St. Cloud share this climate record?

4 places have no NOAA station with 1991-2020 normals of their own, and this station is the nearest full record. A place's own climate can differ from these figures, by several degrees where it sits much higher or lower than the station, nearer the coast, or inside a large city's heat; for the larger places the next nearest records are named with their yearly mean, so the spread around them is visible, and places of 50,000 or more have their own page with NOAA's gridded normals.
