National Weather Service forecasts a high near 61°F for Seattle-Tacoma International Airport (KSEA) on May 13 under partly sunny skies with southwest winds of 10-13 mph, but morning rain and persistent marine stratus over Puget Sound have delayed warming, keeping early temperatures near 54°F and driving trader consensus toward 58-59°F at 43.6% implied probability over 60-61°F at 36%. Onshore flow moderates highs climatologically below May averages around 65°F, with model uncertainty centering on stratus clearing timing—early burn-off could push toward 62°F, while prolonged clouds cap at 58°F. Real-time KSEA observations and afternoon updates will clarify the peak before evening resolution.
