Highest temperature in Hong Kong on July 6?

Platform comparison

Market context

Hong Kong on 6 July 2026 faces a peak summer day where the Hong Kong Observatory will record the absolute daily maximum temperature in degrees Celsius, with settlement tied to a specific Celsius range. The crowd-implied probability for a "YES" outcome on this contract sits at 0%, a stark divergence from the typical early-July climatology where average highs hover between 28°C and 32°C, and the hottest months are historically July and August[3].

Historical data frames this near-zero probability as an anomaly rather than a baseline expectation. In typical early-July conditions, average minima remain around 26°C amid frequent cloud cover and moisture, while the seasonal forecast for July to September 2026 predicts normal to above-normal temperatures for Hong Kong[2][4]. The Polymarket lines show negligible volume across all ranges (24°C to 27°C), with each outcome holding less than 1% probability, suggesting the market is pricing in a highly unlikely cooling event or a data gap rather than the standard 32°C peak heat[1].

Traders must monitor the Hong Kong Observatory's "Daily Extract" publication schedule, as the market cannot resolve until the "Absolute Daily Max" is finalized[5]. The immediate forecast for 06 July indicates temperatures of 27–31°C with a medium-high probability of significant rain, which could suppress peak highs but rarely below 27°C[5]. Analysts note that stagnant, humid overnight conditions with light winds typically push low temperatures into the 27°C range, making a sub-27°C maximum highly improbable unless a typhoon or severe front intervenes[8]. The primary dependency remains the official data release, as no resolution occurs until the relevant extract is published.
