Charleston
Charleston was laid out in the 1670s by colonists who already understood the climate would try to kill them. The grid is narrow, the lots are deep, and the Charleston Single House — one room wide, side-piazza facing south — is a 17th-century air-conditioner that still works. The Battery’s live oaks carry the rest. At 32.78°N the noon sun crests near 81° and the July dew point sits in the 70s; our routing reads the colonial footprint block by block, and the oaks are a bonus we don’t yet model.

- 01White Point Garden to Rainbow Row
The Battery’s live oaks are the canopy the brick can’t throw — three-century crowns over East Bay until the row-house wall takes over at Tradd.

King Street is the long commercial spine — narrow enough that the three- and four-story walls hand off cover all the way down. The west sidewalk holds through 2 p.m.; we cross at Calhoun.

Pineapple Fountain is full sun; the route inland through the warehouse blocks of Vendue and State is the honest one. The Market shed does the last stretch.
