Trader sentiment favors warmer-than-average highs in San Francisco on March 24, with 38% implied odds for 74°F or higher driven by the latest NOAA and ECMWF model ensembles projecting a strengthening high-pressure ridge over Northern California, potentially overriding the typical marine layer cooldown from the Pacific. This setup echoes historical late-March patterns where offshore flow pushes temperatures into the low-to-mid 70s, well above the 62°F climatological average at SFO. Recent GFS updates have trended 2-4°F warmer since yesterday, boosting upper-bin probabilities, while lingering low-confidence fog risks keep mid-60s outcomes viable at around 12.5% each; traders eye this afternoon's 18Z model runs for resolution shifts.
