Trader consensus on Polymarket heavily favors a high of 72°F or higher (75% implied probability) for San Francisco on April 3, mirroring the National Weather Service's latest forecast of sunny skies with highs near 74°F under moderate offshore flow. This warmth stems from a persistent high-pressure ridge over the eastern Pacific, suppressing the typical marine layer and enabling stronger diurnal heating—a pattern solidified after the Bay Area's record hottest March on record, where average temperatures exceeded norms by several degrees. Model ensembles from NOAA show strong agreement on above-normal conditions, with north-northeasterly winds 9-18 mph aiding compression of cool coastal air. While inherent forecast uncertainty remains due to microclimates and exact peak timing at official stations like downtown or SFO, real-time observations today will drive final positioning as the market resolves.
