**Trader consensus has locked in 74-75°F as the highest temperature recorded in Seattle on August 16, 2026, at essentially 100% implied probability.** This reflects the official maximum temperature observation from the National Weather Service’s Seattle-Tacoma International Airport (KSEA) station, which serves as the standard reference for such resolution criteria. Mid-August climatology in the region typically features highs near 76–78°F under marine influence and weakening ridging, and recent model guidance plus on-site measurements aligned precisely with this range rather than the warmer anomalies seen earlier in the summer. The near-certainty stems from the final verified daily summary released shortly after the observation window closed, leaving minimal room for revision. Only an unprecedented post-hoc data correction or use of a non-standard station could alter the outcome, both of which are exceedingly rare for NWS records.
