Official National Weather Service observations at San Francisco International Airport (KSFO) confirm the highest temperature on April 18, 2026, reached 72°F around 2:45 p.m. PDT amid mostly sunny skies, light west winds, and a stable high-pressure ridge over Northern California—aligning precisely with pre-event NOAA forecast model consensus projecting daytime highs near 69–71°F. This trader consensus at 100% implied probability for 68°F or higher reflects verified ASOS data from the automated surface observing system, which captures peak readings with high reliability. Scenarios challenging this would require rare post hoc revisions to official records, such as equipment malfunctions or data quality issues, though historical precedents show maximum temperatures are seldom adjusted. The market nears resolution pending final Weather Underground validation using KSFO data.
