Highest temperature in Hong Kong on August 2?

Platform comparison

Market context

Hong Kong’s afternoon peak temperature on 2 August will be set by the Hong Kong Observatory’s final **Absolute Daily Max** reading, and the market is currently pricing a very narrow spread around the high-20s, with **27°C** the favourite at **34%** and **28°C** close behind at **32%**. That leaves the book close to balanced, with the underdog end of the strip needing a distinct cooler-than-normal outcome to cash, while the top-end values only become attractive if a trader expects a hotter-than-consensus day than the crowd is currently assigning. [1][15]

For framing, the consensus sits modestly below Hong Kong’s August climatology: the HKO’s August daily normals put 2 August at a mean maximum of **31.5°C**, while broader climate guides typically describe August highs in the low 30s, with showers and high humidity keeping realised maxima variable. [6][8][17] That makes the market’s centre of gravity look conservative rather than extreme, so the main value question is whether the crowd is underweighting a standard hot spell or overestimating the chance of an exceptional spike. On that basis, the favourite cluster around **27°C–28°C** looks like the market’s base case, while **30°C+** is the more obvious contrarian angle if conditions turn sunnier and less disrupted by rain. [1][6]

Traders should watch the Observatory’s daily weather outlooks, the timing of showers or thunderstorms, and whether cloud cover or onshore flow limits daytime heating; in Hong Kong, those short-term features can move the daily maximum more than the monthly average suggests. The market cannot resolve until the relevant Daily Extract is published on the HKO climatological information page, so the practical catalyst is not a headline announcement but the final data release itself, after the day has closed and the Observatory has finalised the record.

Methodology

This page is a comparison snapshot: one live quote, four reference venues with their key attributes, and a single execution path — every trade button routes to Who Will Win, which mirrors the Polymarket order book directly.

Resolution & payout

At resolution the UMA oracle takes over: a proposer posts the outcome with a bond, any token holder can dispute within two hours. Without dispute the result is accepted and the smart contract distributes USDC instantly.

On Kalshi (CFTC-regulated) resolution runs through their in-house clearing engine in USD. Betfair Exchange settles after match end in the account's local currency. Manifold pays no cash — only its in-platform "mana" currency.
