Minneapolis vs St. Louis

Minneapolis

Minneapolis has one of the most extreme four-season climates of any major US city — hot humid summers (highs 28–32°C with serious thunderstorms), brutally cold winters (lows -25°C in January, snow on the ground November–March), and pleasant transitional spring and autumn. The city is built for cold; the 9.5-mile downtown Skyway system means you can spend a week downtown in -20°C weather without a coat. Summers are surprisingly humid and outdoor-oriented.

St. Louis

St. Louis has a humid continental climate at the southern edge — hot, humid summers (heat index regularly above 38°C / 100°F in July–August), cold winters with occasional ice storms, and dramatic spring weather including tornado risk in March–May. The city sits in the lower Tornado Alley and has a functional warning siren system. Spring (April–May) and autumn (September–October) are the only months without weather extremes.

Minneapolis

Minneapolis has good but not excellent public transit for an American city of its size — Metro Transit runs the Blue Line and Green Line light rail (connecting the airport, downtown Minneapolis, the U of Minnesota, and downtown St. Paul) plus an extensive bus network. The Skyway system connects 80 downtown blocks at the second floor (an indoor walking network for cold weather). Lakes and outer neighborhoods need a bike, bus, or car. Driving and parking are easy by big-city standards.

Walkability: Downtown Minneapolis is fully walkable in summer (flat, generous sidewalks, the Nicollet Mall central spine) and in winter via the Skyway system (the largest indoor walking network in the world). Uptown and the Chain of Lakes are walkable in their own context but require transit/bike to reach from downtown. Mill District, North Loop, and Northeast are all walkable internally with bike or bus connections to each other.

St. Louis

St. Louis is a driving city — the metro area sprawls 60 miles end-to-end and the dominant mode of transport is the private car. The MetroLink light rail (two lines, blue and red) connects the airport, downtown, Forest Park, Clayton, and East St. Louis on a single useful axis; MetroBus covers the rest. Most visitors rent a car for at least part of their stay, particularly to reach The Hill, Soulard, and the Botanical Garden. Uber and Lyft operate everywhere and are inexpensive ($8–$25 for most trips within the city).

Walkability: Inside individual neighbourhoods (Soulard, The Hill, Central West End, Forest Park) walking is excellent. Between neighbourhoods St. Louis is a driving city — distances are real Midwest distances and surface streets are fast but built for cars, not pedestrians. The Delmar Loop in University City is the longest pure pedestrian commercial strip; the Old Courthouse-to-Arch riverfront is the most photogenic walk.
