Polymarket
This market tracks whether the lowest temperature recorded in Hong Kong will fall within the 28°C range on May 29, 2026. On Polymarket, the leading outcome—a low of 28°C—stands at 98.6%, while the alternative outcome of 27°C holds 0.5%. Resolution will be determined by the Hong Kong Observatory's official daily temperature data, specifically the "Absolute Daily Min" figure measured to one decimal place. Watch for the Hong Kong Observatory's finalized temperature reading on May 29, 2026, which will settle this market once the data is officially recorded.
The market resolves on May 29, 2026, after the lowest temperature in Hong Kong on May 29 has been recorded and verified. Resolution depends on official temperature data from the relevant meteorological authority for Hong Kong. The specific temperature threshold or range that determines each outcome is defined in the market's resolution criteria. Traders should review the exact outcome definitions before trading to understand which temperature readings will trigger each resolution state.
Major weather pattern shifts, tropical cyclone activity, or monsoon onset timing could significantly move odds. Updated seasonal forecasts from meteorological agencies and real-time atmospheric models will influence trader positioning. Historical May temperature anomalies and climate oscillations like the Indian Ocean Dipole or El Niño conditions may be priced in. As May 29 approaches, short-range weather forecasts become more precise, typically causing sharper price moves. Urban heat island effects and local pollution levels can also affect minimum temperatures, making regional air quality reports and urban development news relevant catalysts for prediction market repricing.
