Highest temperature in Seattle on July 22?

Platform comparison

Market context

Seattle-Tacoma International Airport’s highest temperature on 22 July 2026 has now resolved into the **94-95°F** range, which is the market’s current frontrunner at 100%. That aligns with a warm summer pattern in the Puget Sound area, where afternoon highs can be materially higher than the morning reading and the airport station is the specific settlement reference, not Seattle city averages.

The 0% implied probability on **YES** is best read as a post-event or near-certain pricing signal rather than a live forecast. In comparable temperature markets, the relevant comparison is not “will it be hot?” but whether the recorded airport maximum falls within the exact settlement band on the Wunderground daily history page. Because the market settles on the highest observed temperature for the day at KSEA, any late-day reading or data correction on the source page matters more than broader weather commentary.

From a market-access perspective, the main constraints are regulatory and account-based rather than weather-based. German **GlüStV** rules can limit or block access where a venue is treated as gambling, while the **US CFTC** has asserted broad reach over derivatives-style event contracts, so availability can differ sharply by jurisdiction. “**No-KYC up to $1,500**” means some users may trade within that threshold with lighter identity checks, but access to this specific market still depends on the platform’s country restrictions, wallet controls, and whether the user clears any required compliance checks before placement.
