Boston

Boston’s streets weren’t drawn — they were walked into shape by cows, colonists, and landfill committees. The result is shade geometry no grid model can guess: Beacon Hill stays cool by accident of 1799, Back Bay by Haussmann-era intent, the Esplanade not at all. Our routing reads every footprint and picks the lane the sun forgot.

Stay Cool routes around shade in Boston, MA. The app picks the cooler side of every street using real building heights and live sun position — peak summer UV here is 8, average July high is 82°F, and tree canopy covers 27% of the city. Below: the most reliably-shaded walking routes we've found, plus deeper neighborhood field notes when available.

    Freedom Trail, Beacon Hill leg

    Skirts Government Center’s griddle, then dives into the brick warren where 18th-century lots throw 21st-century shadows.
