• Embrace the indoor infrastructure: St. Paul features extensive skyway systems and indoor connections that help pedestrians navigate downtown without stepping into the freezing wind.
• Drive with caution: City snowplows work efficiently, but black ice and slick roads require winter tires and cautious driving habits.

Spring: The Great Thaw and Variable Skies

Spring in St. Paul is a season of dramatic transition. April and May bring the melting of the winter snowpack, rapidly greening landscapes, and a return to outdoor life. However, spring weather is notoriously unpredictable.
