San Francisco braces for cooler June 22 amid lingering marine layer
Highest temperature in San Francisco on Jun 22, 2026?
Kalshi prices this 67° or below at 99%. The reporting broadly agrees.
San Francisco’s weather service predicts a marine layer and spotty drizzle on June 22, keeping the day's high temperature well below the seasonal average and reducing the chance of a record‑breaking heat day. The cooler outlook aligns with the market’s heavy tilt toward 67 °F or below, as traders have priced 99% on that outcome. The forecast comes as the Bay Area grapples with a broader California heat wave that has already pushed temperatures above normal in many inland locations, prompting public health advisories and renewed climate‑change discussions. Local officials will monitor the day’s readings closely, especially as the city prepares for a weekend of baseball at Oracle Park.
Background
San Francisco’s June climate is traditionally moderated by the Pacific, with average highs around 64 °F and a strong marine influence that often brings fog and drizzle. The city’s all‑time June high of 71 °F was set in 2006, a rare spike that required an inland heat surge. Recent weeks have seen an unprecedented heat dome over California, driving record temperatures in the Central Valley and prompting state‑wide heat‑health alerts. Against that backdrop, the National Weather Service’s daily climatological report will determine whether June 22 joins the list of unusually warm days or remains a cooler outlier.
The precedent
- San Francisco’s all‑time June high is 71 °F, recorded on June 28, 2006
