SFO's bay-side marine influence keeps highs cool and the daily range narrow — a low-variance market; we track the 5-minute ASOS. polyweather.today tracks minute-by-minute runway temperatures from San Francisco Int'l (KSFO) (KSFO) — the same sensors behind the official METAR — and turns the trend into a next-METAR nowcast, so you can read where San Francisco's temperature is heading before the next METAR prints.
A METAR is the airport's official routine weather observation (the TAF is the matching forecast). San Francisco Int'l (KSFO) issues a new KSFO METAR roughly every 30–60 minutes, and daily-high temperature markets settle on those reports. The latest raw KSFO METAR is shown at the top of this page, the board lists recent reports with decoded temperatures, and between two reports the minute-level runway feed shows where the next METAR is heading.
