Annual Water Temperature Trend

Berkeley sits on the eastern shore of San Francisco Bay, where tidal currents and the cool California Current keep surface water temperatures relatively low year-round. Typical bay water temperatures range from about 10–12 °C in the coldest winter months, rise to roughly 11–14 °C in spring, and commonly sit between 12–16 °C during the warmest weeks of late summer. Autumn temperatures generally fall back toward the lower double digits as upwelling and Pacific fog increase. Local variations occur depending on wind, tides and sheltered versus exposed spots, so small coves and marinas can feel a few degrees warmer on calm, sunny days while open portions of the bay remain brisk.
