Minneapolis experiences a hot-summer humid continental climate, characterized by four distinct seasons and significant temperature variations throughout the year. This climate results in cold, snowy winters and warm, humid summers.
Seasonal Weather Patterns
Winter (Late November – Mid-March)
Winters in Minneapolis are notably cold, with temperatures frequently remaining below freezing for extended periods. January is typically the coldest month, averaging highs of 23°F (-5°C) and lows of 7°F (-14°C). Arctic air masses can push temperatures well below 0°F (-18°C), accompanied by biting winds that create dangerous wind chill factors. Snowfall is common, with an average annual accumulation of 48 to 55 inches.
Spring (March – May)
Spring brings a gradual warming trend. March sees average temperatures around 40°F (4°C), rising to 68°F (20°C) by May. This season is marked by melting snow and budding flora, though weather can be unpredictable, with occasional late snowfalls or early heatwaves.
Summer (June – August)
Summers are warm and humid, with average highs reaching 83°F (28°C) in July, the warmest month. Thunderstorms are common, contributing to the season’s higher precipitation levels. The city experiences long daylight hours, providing ample time for outdoor activities.

Impact of Climate Change
Recent data indicates that Minnesota’s climate is becoming warmer and wetter. Average temperatures have increased by nearly 3°F, and extreme heat events are on the rise. These changes pose challenges such as increased strain on agriculture, more frequent heavy rainstorms, and threats to local ecosystems.
In response, the City of Minneapolis has adopted the Climate Equity Plan, aiming to significantly reduce climate pollution by 2030 and achieve carbon neutrality by 2050. This plan emphasizes environmental justice and seeks to create a healthier, more prosperous future for all residents.
Understanding these seasonal patterns and the ongoing impacts of climate change is essential for residents and visitors alike to prepare for and adapt to Minneapolis’ evolving climate.
