Weather report 19 October 2026, 12:00

San Francisco is still cooling down after the weekend: from 16 °C around midday, the temperature edges up to about 17 °C before dropping to 14 °C by 18:00. Thick cloud takes over during the afternoon, but no rain is expected. It stays dry through Tuesday lunchtime.

Overnight stays mostly overcast and dry. Temperatures ease to around 12 °C, while the wind drops to 8–12 km/h and shifts from west to south.

Tuesday begins grey but dry, with temperatures rising from about 12 °C to 17 °C by 12:00. No rain is forecast up to then, and the wind stays light at 10–14 km/h.

A few showers are possible on Wednesday between 05:45 and 11:00, though little rain is expected at around 18 °C. Thursday will be the coolest day of the week, at 16 °C with some rain. The sun returns on Friday, and the weekend turns noticeably milder at around 24 °C.

Open-Meteo's model history shows a steep fall: 30 °C on Friday was followed by 28 °C on Saturday and only 18 °C on Sunday. This was not a multi-day heatwave, as just one day reached the 30 °C threshold. The present cool spell is therefore a sharp break rather than a continuation of October's warm spell; conditions stay settled until Wednesday's shower risk.

Today's wind comes from the west and picks up to 15–20 km/h in the afternoon, with gusts near 29 km/h. It eases after 18:00. On exposed bridges and along the coast the wind will be more noticeable than in sheltered neighbourhoods.
