Weather report 19 October 2026, 07:00

After a short warm spell and a windy Sunday, San Francisco starts Monday at 12 °C with a cool, initially dry morning. The sun breaks through at times before thick cloud takes over in the early afternoon, and temperatures struggle past 16 °C. Rain is not an issue today: the precipitation data are complete and indicate no rain through midnight.

The night stays mostly cloudy and around 12 °C, so a jacket is still worth having. The westerly wind eases after 22:00 to about 9–11 km/h.

Tuesday turns milder at 18–19 °C and stays dry at first. The chance of rain increases overnight into Wednesday, with the main rain reaching San Francisco on Wednesday.

Wednesday brings rain at 17–18 °C before the weather settles on Thursday, when a few showers may still linger. The weekend turns sunnier and much warmer, with 24 °C on Saturday and 24 °C on Sunday. From next Tuesday, a slow cooling trend may set in, though that remains an uncertain signal.

The model history shows 30.1 °C on Friday, then only 18.2 °C on Sunday. A run of several days at or above 30 °C is not supported by the data. Wednesday brings the next clear change with rain before a dry, warmer spell builds towards the weekend. Whether that spell lasts cannot be established from the available data.

The westerly wind will generally blow at 13–19 km/h, with gusts up to 29 km/h. It will be most noticeable on the coast and on exposed bridge sections during the morning and early afternoon.
