Official National Weather Service observations at San Francisco International Airport recorded a daily maximum of 71°F on June 5 under sunny skies and persistent high pressure that suppressed the typical marine-layer cooling. This outcome aligns with early-June climatology, where highs commonly reach the upper 60s to low 70s, and short-range forecast models showed strong consensus around 71°F with minimal spread. The near-100% market-implied probability for 66°F or higher therefore reflects verified post-event data rather than projection. An unexpected strengthening of onshore winds or thicker afternoon stratus could have lowered the peak, but those conditions did not develop.
