Full text

* WHAT...Hot conditions with maximum temperatures in the low-80s to low-90s. Mild minimum temperatures and weak onshore flow will limit overnight relief. * WHERE...The Marin Hills, San Francisco, and Northern Salinas Valley/Hollister Valley and Carmel Valley. * WHEN...From 11 AM this morning to 10 PM PDT Sunday. * IMPACTS...This level of heat affects anyone without effective cooling and/or adequate hydration. Impacts likely in some health systems, heat-sensitive industries and infrastructure.

Hydration is a critical piece to surviving the heat. Drink water, and if possible, take water to those who are vulnerable. Take extra precautions when outside. Wear lightweight and loose fitting clothing. Try to limit strenuous activities to the early morning or evening. Take action when you experience symptoms of heat exhaustion and/or heat stroke. Beat the heat and check the backseat! Do not leave young children or pets in unattended vehicles. Car interiors will reach lethal temperatures in a matter of minutes.

About this San Francisco forecast

Updated 2026-10-03 10:58 UTC, and refreshed automatically every few minutes. Forecast data is provided by Visual Crossing; radar frames from RainViewer; the 20-year normals and records from the ERA5 reanalysis archive. No national weather service publishes point alerts here, so only computed watches are shown.

Watches labelled computed are worked out on this site from forecast thresholds and are not official warnings — always defer to your national weather service. Need help reading a number? See the sourced weather guide.
