Official National Weather Service observations at San Francisco International Airport (KSFO)—the authoritative station for market resolution—recorded a high temperature of 64-65°F on May 10, anchoring trader consensus at a 100% implied probability for this bin amid negligible 0.1% odds for 66°F or higher. Persistent marine stratus clouds and gusty westerly winds (10-20 mph) from a cool Pacific air mass limited solar heating and adiabatic warming, aligning with climatological norms where May highs average 67°F but frequently stall in the low 60s under overcast conditions. This positioning reflects finalized automated surface observing system (ASOS) data, with model forecasts from NOAA's Global Forecast System accurately previewing subdued temps 24-48 hours prior. Realistic challenges are minimal, limited to rare post-processing revisions from quality control or discrepancies with backup downtown sensors, though KSFO data carries precedence; market awaits Wunderground's archived history for final confirmation.
