San Diego Ride Guide
San Diego is year-round riding paradise — coastal climbs, flat island loops, and canyon roads. The afternoon sea breeze from the west is the main variable on most rides.
Climatology
Mild and dry almost always: 60–78°F by the coast year-round. A gray marine layer ("May Gray / June Gloom") burns off by midday in early summer. Inland and the climbs run noticeably hotter.
