Highest temperature in Hong Kong on July 24?

Platform comparison

Market context

Hong Kong’s weather has turned hot and unstable over the past 24–48 hours, with the Observatory warning that a low-pressure system east of the Philippines could strengthen and bring unsettled conditions to the territory later this weekend. At the same time, the latest outlook points to a brief spell of mainly fine, very hot weather before the pattern deteriorates, with daytime temperatures around 32–33°C ahead of the change. [12]

That backdrop matters because July in Hong Kong is normally a high-heat month: average daytime highs sit near 31–32°C, with daily highs often around 89°F and rarely much above 94°F. The Observatory’s seasonal forecast for July to September 2026 also leans normal to above normal for temperature, which fits a market that is currently priced as a low-probability “YES” outcome rather than a routine summer heat case. [3][11]

For traders, the key catalysts are the Observatory’s short-range bulletins, any tropical-cyclone track updates, and the final daily extract published after the settlement day. If the nearby system shifts away or weakens, a hot, sunny interval could allow the day’s maximum to push up; if cloud, rain, or squally showers arrive sooner, they would cap the high more quickly. The market cannot settle until the Hong Kong Observatory publishes the final “Absolute Daily Max” for 24 July 2026 in its Daily Extract.

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 Prediction Today, 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.
