Highest temperature in Hong Kong on July 27?

Platform comparison

Market context

Hong Kong’s observed maximum on 27 July will be taken from the Hong Kong Observatory’s Daily Extract, so the key number is not a citywide average but the single highest official reading for the day. In late July, Hong Kong is normally in its hot, humid monsoon season: WeatherSpark puts typical daily highs around 89°F, with extremes rarely below 85°F or above 94°F, which translates to a broad but still fairly warm range for the market to settle into.[3] EaseWeather also flags a very wet July pattern, with significant rainfall expected across the month, a reminder that cloud cover and showers can cap daytime heating even when the broader climate is hot.[1]

That backdrop helps explain why ultra-low outcomes can be competitive in isolated sessions, but the market’s 0% YES pricing for the present line suggests traders are currently leaning away from a clear breakout heat event.[2] The main reference point is the recent July 19 contract, which resolved at 30°C after the Hong Kong Observatory confirmed that daily maximum, showing that these markets can and do settle firmly on the official extract rather than on forecast chatter or live weather feeds.[4]

The practical catalysts are straightforward: the Observatory’s final publication timing, any late-day thunderstorms or prolonged rain bands, and whether cloudier conditions suppress the afternoon peak before the 12:00 UTC settlement cut-off. Because resolution depends on the finalised Daily Extract and not on intraday headlines, traders will be watching the official update schedule more than speculative forecasts, especially if convection builds after dawn or if a rain-soaked start leaves the day with little headroom for the temperature to climb.[1][4]

What are live sports odds on Polymarket?

How fast do sports winnings settle?

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.

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.
