توقع: Lowest temperature in Hong Kong on July 31?

Platform comparison

Market context

Hong Kong Observatory readings for 31 July are usually far above anything that would make **3%** look cheap, because the city’s July overnight minima are normally in the high-20s Celsius and even the monthly record set is only **24.5°C** for July 31, 2019.[1][2][3] The market is therefore pricing in a genuinely unusual cool spell, not a routine summer outcome. That matters because the settlement source is the Observatory’s final “Absolute Daily Min (deg. C)” for the date, so only a clearly depressed morning minimum would move the result into the lower temperature bands.[3]

The main comparables for traders are the rare rain- and storm-driven dips that can drag Hong Kong well below its usual July floor. In 2019, Wipha’s rainbands brought more than 100 mm to most areas and the Observatory fell to **24.5°C** on 31 July, while in 2022 heavy rain on 1 July pushed the month’s minimum to **25.4°C**.[3][12] By contrast, the July climatology still shows typical lows around **27–28°C**, with recent daily examples on 31 July often clustering around the upper 20s.[1][2][7] That historical spread implies that anything in the mid-20s is an outlier, but not impossible if a rainstorm or tropical system crosses the territory.

The key catalysts are the Observatory’s hourly and daily updates, plus any weather warnings or rainband forecasts that can hint at overnight cooling before the final extract is published.[7][16] Traders should watch for late-day convection, tropical cyclone proximity and persistent rain, because those are the mechanisms most likely to suppress the minimum temperature below the usual July range.[3][7] If conditions stay broadly typical, the line should continue to lean towards a warm minimum, with the current low YES probability reflecting how uncommon a sub-26°C outcome has been in the historical record.[1][2][3]

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.

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.

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.

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.
