Pittsburgh vs St. Louis

Pittsburgh

Pittsburgh has a humid continental climate with four distinct seasons — warm humid summers (highs 28–30°C), cold snowy winters (lows -5°C, snow on the ground much of December–March), and pleasant transitional spring and autumn. The valley topography traps cloud cover; Pittsburgh averages 200 cloudy days a year (more than Seattle by some measures). The fall foliage in late October is among the best in the eastern US.

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.

Pittsburgh

Pittsburgh has stronger public transit than peers expect — the Port Authority (Pittsburgh Regional Transit) runs 100+ bus routes, the T light rail (free in downtown), and the two surviving Inclines. Downtown, Strip District, North Shore, and Oakland are walkable and connected by frequent buses. Outer neighborhoods (Lawrenceville, Bloomfield, Shadyside, Squirrel Hill, Mt. Washington) need a bus, light rail, Uber, or car. Driving downtown is hostile — avoid renting a car for an in-city stay.

Walkability: Pittsburgh's walkability varies dramatically by neighborhood — Downtown, Strip District, North Shore, South Side Flats, Lawrenceville, and Squirrel Hill are all comfortably walkable with flat-to-rolling streets. Mt. Washington, Polish Hill, and the South Side Slopes are vertical hiking. Plan for the topography; the shortest line on Google Maps is often a 200-foot climb.

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.
