Highest temperature in Seattle on May 30?

Highest temperature in Seattle on May 30? is a weather prediction market asking traders to forecast the hottest temperature recorded at Seattle-Tacoma International Airport on May 30, 2026. The event resolves to the temperature range containing the day’s highest reading, based on Wunderground’s historical data for the Seattle station, with values measured in whole degrees Fahrenheit. Because the market uses the first published datapoint for the following date as the cutoff, late revisions before that point can still affect the final outcome. The market is relevant for anyone following Seattle weather, daily temperature patterns, and short-term weather forecast dynamics.

As a recurring weather event, it highlights how prediction markets translate real-world conditions into tradable odds and event prediction. Current market probability is 84.5%, suggesting traders expect a relatively high chance that the specified temperature range will resolve as anticipated, though the result remains dependent on the official source data. The market opened on May 28, 2026 and is scheduled to close on May 30, 2026, making the timing tightly linked to the day’s observed high temperature and final resolution criteria.
