Climate in Mankato, MN

Mankato climate

Mankato offers warm summers, cold winters, snow, and a river shaped by the same weather

NOAA 1991 to 2020 normals for the Mankato station show a mean annual high of 55.4 degrees Fahrenheit, a mean annual low of 35.1 degrees, and a mean annual temperature of 45.3 degrees. January averages a high of 23.7 degrees and a low of 5.7 degrees. July averages a high of 81.9 degrees and a low of 61.7 degrees. Annual precipitation averages 33.88 inches and annual snow averages 38.7 inches.

The station records precipitation on about 98.7 days each year, about 161 days with a minimum at or below 32 degrees, and about 28 days at or below 0 degrees. The catalog calls the climate mild and records 69 percent humidity in a July 10, 2026 observation, but that humidity figure is a point in time rather than a yearly average. Summer heat, thunderstorms, ice, snow, and river levels can all change the best time for an outing or care trip.

Inspect heating, insulation, windows, roof, gutters, pipes, basement, drainage, snow storage, ice treatment, trees, power backup, air conditioning, and the route to care. Ask how quickly streets, sidewalks, bus stops, and parking are cleared, and keep warm indoor activities ready for days when a storm or flood changes the schedule. A comfortable summer visit cannot answer the winter home question by itself.

Mankato in everyday life

Could Mankato work for you?

What may work well

Warm summers and a river valley setting support parks, trails, events, gardens, and outdoor family visits.
NOAA normals give concrete starting figures for temperature, rain, snow, freezing days, and winter home planning.
The library, history center, art center, event center, university, and home activities provide alternatives when weather changes an outing.

What to think about

January cold, snow, ice, freezing pipes, short daylight, and below zero nights can limit mobility and raise spending.
River, drainage, basement, roof, trees, power, snow, insurance, and road conditions vary by address.
A mild catalog label should not be mistaken for a low maintenance winter or a promise of comfortable river weather.
