Highest temperature in Hong Kong on May 31?

Highest temperature in Hong Kong on May 31? is a weather prediction market that asks traders to forecast the highest temperature recorded by the Hong Kong Observatory on 31 May 2026. The market will resolve to the temperature range containing the day’s absolute daily maximum in degrees Celsius, using the Hong Kong Observatory’s finalized Daily Extract as the resolution source. Because the observatory reports temperatures to one decimal place, the event outcome depends on the published reading for that date and any later revisions are ignored. The market opens on May 29, 2026 and is scheduled to remain open until May 31, 2026, when the relevant data becomes available. Current market probability is about 5%, suggesting traders assign relatively low odds to this temperature range being the eventual result. As a recurring Hong Kong weather event, it draws attention from participants tracking daily temperature forecasts, market sentiment, and short-term climate conditions in the city.
