Today at the club, the water temperature is a chilly 55F, slightly up from last month's 53.4F, and the air will warm up to 63F by the afternoon. There's a moderate flood in the early afternoon, and a moderate ebb will strengthen in the evening, so swimmers should be cautious near Muni Pier during the ebb. Sunny skies and a windy WSW breeze of 20 mph are expected, making for potentially choppy waters in the afternoon, which may not be ideal for shell rowing but can offer exciting conditions for surfski.
