Polymarket
This market tracks the lowest temperature recorded in Hong Kong on May 30, 2026, as measured by the Hong Kong Observatory. On Polymarket, the leading outcome—that the lowest temperature will be 27°C—stands at 34.0%, while the second outcome of 26°C holds 26.5% probability. Resolution will use the Hong Kong Observatory's official daily temperature data, measured to one decimal place. Watch for the Hong Kong Observatory's publication of the "Absolute Daily Min" temperature reading for May 30, 2026, which will determine the final outcome.
The market resolves on May 30, 2026, after the lowest temperature recorded in Hong Kong on May 30 is finalized. Resolution hinges on the official temperature reading from the designated weather authority for that date. Once the actual low is confirmed, the outcome contract matching that temperature threshold settles to 100 cents, while all other contracts settle to zero. Early resolution is possible if the temperature falls outside all predefined ranges, depending on market rules.
Major weather pattern shifts, tropical cyclone activity, or monsoon onset timing could significantly move odds for Hong Kong's May 30 low. Updated seasonal forecasts from meteorological agencies, anomalous atmospheric pressure systems, or sudden shifts in ocean temperatures may trigger trader repositioning. As May approaches, real-time weather models become more precise, allowing traders to refine probability estimates. Historical climate data for late May and any unusual global weather events could also influence market pricing before the resolution date arrives.
