توقع: Highest temperature in Hong Kong on August 3?

Platform comparison

Market context

Hong Kong’s highest temperature on 3 August will be set by the Hong Kong Observatory’s final “Absolute Daily Max” reading, so the key question is whether the city stays in the high-20s or breaks into the low-30s. The market is currently leaning to 27°C and 28°C, with 27°C priced as the frontrunner and 32°C or higher given a sub-1% chance, reflecting a view that cloud and showers will cap the day’s peak rather than allow a full heat spike.[1]

That pricing sits against a climate pattern that usually makes August one of Hong Kong’s hotter months, with typical ranges commonly cited around the high-20s to low-30s Celsius, but daily maxima can still move sharply when rain bands or coastal winds arrive.[4][13] Recent local reporting also shows how quickly Hong Kong can swing into severe heat, with the Observatory and media outlets recording days this year above 34°C in the city and even higher inland readings, which is why traders cannot dismiss a late hot spell entirely.[9][11] At the same time, the market description notes that the outcome will be based on the published Daily Extract and that later revisions will not count, so the first finalised figure matters most.[1]

For traders, the main catalysts are the Observatory’s day-of forecast updates, the actual afternoon weather across the territory, and the timing of the final daily extract publication.[5][10] If showers persist or extensive cloud cover holds through the afternoon, the ceiling for the reading should remain closer to the current 27–28°C cluster; if skies clear and urban areas heat up, the probability mass can shift towards 29°C or above. The relevant uncertainty is not just the citywide headline forecast but whether the Observatory’s own station records a warmer short-lived peak before rain arrives.[1][10]

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.
