Market context
The Hong Kong Observatory will record the highest temperature in Hong Kong on 28 July 2026, measured to one decimal place in Celsius. This date falls within Hong Kong's peak summer season, when the territory typically experiences its most intense heat. The settlement window closes at midday UTC on that date, though final resolution depends on the Observatory publishing its daily extract data, which may take several days after the actual observation period.
Hong Kong's July temperatures have historically clustered in the 32–35°C range for daily maxima, with extremes occasionally breaching 36°C during particularly intense heat waves. The territory's all-time record high stands at 39.9°C, recorded in September 1998. July averages sit around 33–34°C, making it one of the hotter months but not the absolute peak; August typically edges slightly warmer. Traders should note that the 0% crowd probability likely reflects uncertainty about which specific temperature band will resolve rather than any expectation of anomalous cold.
Key variables affecting the outcome include the strength of the Pacific high-pressure system and any tropical cyclone activity in the region during late July. The Hong Kong Observatory issues extended forecasts roughly two weeks ahead, though precision for specific daily maxima remains limited beyond seven days. Humidity levels and urban heat island effects in central Hong Kong can push recorded temperatures higher than surrounding areas. Resolution hinges entirely on the Observatory's published data; no alternative sources are accepted under the market terms.

FAQ
- Are prediction markets better than sports betting?
- Prediction markets tend toward tighter odds than bookmakers because they use peer-to-peer exchange rather than bookmaker margin. On major matches, Polymarket quotes typically sit 2-5% closer to the true probability model than bet365 or DraftKings.
- What are live sports odds on Polymarket?
- Some top-tier matches stay open during play — you can trade the half-time probability in the 70th minute. Polymarket mid-prices update second-by-second; any frontend mirroring the order book shows the same movement.
- Which sports markets are available?
- Football (soccer) dominates — Champions League, World Cup, Premier League, La Liga, Bundesliga — followed by NFL, NBA, tennis Grand Slams, Formula 1, boxing/MMA. Resolution via official league source confirmation.
- How fast do sports winnings settle?
- Once the official league outcome is logged in the UMA Oracle (typically 1-2 hours after the final whistle), Polymarket's smart contract triggers USDC payout. To your wallet within minutes.
- What's the difference between match odds and outright odds?
- Match odds cover a single game ("Bayern beats BVB"). Outright odds are long-term aggregates ("Bayern wins the league"). Outright markets have deeper liquidity; match markets have faster resolution.
