South Bay microclimates: San Jose runs noticeably warmer and drier than SF and the Peninsula. The Diablo Range east of downtown shields from coastal fog, so summer afternoons routinely cross 90°F. The Santa Cruz Mountains keep things foggier and cooler along the western edge (Saratoga, Los Gatos, Boulder Creek).
