Seattle’s official high temperature on June 15, 2026, reached 89 °F at Seattle-Tacoma International Airport (KSEA), the station used for market resolution. This outcome aligned with National Weather Service forecasts issued in the preceding days that projected a strong thermal ridge and downslope warming under clear skies, pushing values 15–20 °F above the June normal of ~71 °F and matching or slightly exceeding the 1963 record of 88 °F. Model consensus from ECMWF and GFS runs supported surface maxima in the upper 80s to low 90s, with limited cloud cover and light northerly flow preventing greater mixing or marine intrusion. The 100 % market-implied probability on 88–89 °F reflects this verified observation; only an unreported station error or post-event data revision would alter the result.
