US · Published Aug 12, 2026
San Diego is experiencing humid conditions with monsoon storms expected in the mountains and deserts on Tuesday, August 10,
A Coastal Flood Advisory is in effect until 11 PM Wednesday due to astronomical high tides, which may cause flooding during evening high tides between 7:30 PM and 10 PM, with levels reaching 7.2 to 7.5 feet. Tuesday's high temperatures are forecasted to range from 75-84°F (24-29°C) along the coast, 85-91°F (29-33°C) inland, 80-92°F (27-33°C) in the mountains, and 106-108°F (41-42°C) in the deserts. The chance of storms will taper off by Wednesday, with cooler and less humid conditions expected later in the week.

Impact & Risks

The Coastal Flood Advisory poses a risk of flooding along the San Diego coastline during evening high tides. Residents in low-lying coastal areas should remain vigilant. Monsoon storms in the mountains and deserts may bring localized flooding, lightning, small hail, and strong winds. High temperatures and humidity could also pose health risks, particularly for vulnerable populations such as children, the elderly, and those with respiratory issues. Outdoor workers and pets are also at risk from excessive heat.
