Market context
Hong Kong’s **highest temperature on 8 August** is settled by the Hong Kong Observatory’s final “Absolute Daily Max”, so the key question is whether the city delivers an ordinary hot-day peak or something close to a record-type spike. The market is currently priced at 0% YES, but the day’s official reading can still move materially if sunshine dominates and the urban heat builds quickly.
The main historical reference point is 8 August 2015, when the Observatory hit **36.3°C**, the hottest day ever recorded there at the time, with several district stations well above that level[2][4]. For August as a whole, the Observatory’s 1991–2020 daily normal for 8 August shows a much lower pattern, with the average maximum around **31.7°C** and the mean temperature around **29.0°C**[7]. More recently, August 2024 was described by the Observatory as “exceptionally hot”, with a mean daily maximum of **32.3°C** for the month, which is a useful reminder that late-summer heat can still run above normal even without a record-breaking extreme[19].
For traders, the main catalysts are the morning and early-afternoon Observatory readings, because Hong Kong maxima typically peak before sunset and the final value is then fixed in the daily extract once published. At 3 a.m. HKT on 8 August, the Observatory was already at **29°C**, with several urban and outlying stations at 28–30°C, indicating a warm starting point but not yet an outcome[8]. The live forecast line has been very hot for the same date, with AccuWeather showing highs in the upper 90s Fahrenheit for Hong Kong on 8 August, which aligns with a likely low-30s Celsius finish rather than an extreme outlier[1].

FAQ
- When do sports markets resolve?
- Typically within hours of the official final whistle. Polymarket uses UMA Optimistic Oracle with source URLs pointing at official league data feeds — e.g. the Premier League for EPL markets, UEFA for Champions League, FIFA for World Cup.
- Can I bet on individual matches?
- Yes, Polymarket lists every major Premier League / Champions League / World Cup match as its own market. Liquidity varies — top matches like El Clásico or a semi-final often have six-figure pools, lower-league games closer to three-figure.
- 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.
- Can I import form data and lineups?
- This page shows the live Polymarket quote as an implied probability. Form data and lineups must be researched separately via sports data providers (e.g. Soccerway, ESPN, FBref) — we surface the market probability, not the sport analysis.
