San Diego
San Diego’s secret is that it doesn’t need shade the way other hot cities do — the onshore wind is the cooling system, and at 4 p.m. a coastal sidewalk runs 15°F under the same block two miles inland. We model the building geometry where it matters (Gaslamp, downtown, Balboa’s edges); along the coves the route that catches the breeze beats the route that catches the shadow.

- 01Cabrillo Bridge to Spanish Village
Balboa is the canopy moment — eucalyptus and Moreton Bay figs do most of the work the buildings can’t. We route the Prado’s arcaded south side, then duck north under the figs.

The Embarcadero has almost no canopy and the sun sits high — but the bay breeze sets in by 2 p.m. and does what shadow doesn’t.

Coast Walk has cypress, ice plant, and not much overhead — this is a wind route, not a shade route. The Pacific is doing the cooling.
