Trader consensus on Polymarket assigns a 79.5% implied probability to a high of 78°F or higher in San Francisco on April 4, driven by the latest National Weather Service forecasts and model ensembles projecting peaks near 80°F amid a strengthening high-pressure ridge over California. This setup promotes subsidence warming and clear skies, with light offshore winds mixing out cooler marine air layers—upgrading expectations from earlier runs around March 30-31 when probabilities for 74-75°F were higher. Following the Bay Area's record-hot March 2026, current upper-air analyses show ridge amplification 10-20°F above April normals of ~64°F, though persistent coastal stratus could cap outcomes at 76-77°F (14.5%). Watch evening NWS updates for refined guidance ahead of tomorrow's observations at official stations like SFO.
