Highest temperature in Kuala Lumpur on July 27?

Platform comparison

Market context

Kuala Lumpur International Airport is on track for a **wet July**, and this market resolves on the *highest* temperature printed for 27 July, not the daily mean or the evening reading. Polymarket is currently pricing the contract at **0% YES**, meaning the crowd sees little chance that the day’s maximum at WMKK will land in the relevant temperature band; trades here settle in **USDC** on **Polygon**, with outcome shares represented by **conditional tokens** tied to the Wunderground daily history page for the airport station.

That zero price is easier to read against Kuala Lumpur’s summer climate than against a single forecast run. July is typically one of the wetter months in the city, and the available July outlook points to **more than 130 mm of rainfall** across the month with rain on **over 30 days**, which usually constrains daytime highs and makes very hot extremes harder to realise.[1] For a temperature-range market, the practical question is whether a short-lived break in cloud and rain is enough to push the day’s peak into a higher bucket before the settlement window closes at **12:00 UTC**, when local afternoon heating is still relevant but not guaranteed.

Traders will want to watch the station forecast, convective rain timing, and any shift in monsoon-style showers through the day, because the winning band depends on the *recorded maximum* rather than what the forecast says at opening. Any late-morning clearing, storm delay, or forecast revision can matter more here than broad monthly averages, especially when the market starts from a **0%** crowd view and must be read as a live probability on an on-chain contract rather than a fixed weather prediction.[1]

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 Polymarket Alternative UK, 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.
