Highest temperature in Kuala Lumpur on July 30?

Platform comparison

Market context

Kuala Lumpur’s late-July heat is usually pinned in the low 30s Celsius, with the city’s July average high around 31–33°C and nights near 23–25°C, so the market is really about whether the airport station posts an unusually strong afternoon peak rather than an everyday warm day.[1][3][5] For this settlement, the relevant figure is the *single highest temperature* at Kuala Lumpur Intl Airport before the deadline, not the daily mean, so programmatic monitoring should key off the hourly history feed and the day’s maximum value rather than forecast icons or general city averages.[10][2]

The current 0% YES price implies traders are not assigning material odds to a threshold outcome in the required range, which can make sense when the plausible landing zone is already visible in model pages around the low 90s Fahrenheit, or roughly 32–34°C, with only a modest chance of a spike above that in a humid tropical airport microclimate.[10][12][1] Historical July records show that Kuala Lumpur can reach the high 30s Celsius, but those extremes are rare and sit well above the normal July envelope, so any move in probability will likely come from an observed hot spell on the day itself rather than a broad seasonal shift.[5][3]

The main catalysts are the live observations from Kuala Lumpur Intl Airport itself, especially the midday-to-afternoon readings before the settlement window closes, plus any rapid change in cloud cover or rain that suppresses the day’s maximum.[10][2] A practical trading setup would poll the Wunderground history page or scrape the daily maximum field at regular intervals, compare it with adjacent airport observations for confirmation, and update conditional orders as soon as the station prints a new high; there are no major scheduled policy or event dependencies here, so the decisive input is the weather station feed rather than headlines.[10][11]

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 Bot UK, which mirrors the Polymarket order book directly.

Resolution & payout

Settlement runs on-chain. Polymarket's contract logic separates YES and NO shares as conditional tokens; at resolution the winning share lifts to $1.00 and the losing one to $0. The outcome input comes from the UMA Optimistic Oracle, which secures against bad resolution with a bond + dispute window.

Once finalised, the smart contract pays USDC to the holders' wallets within minutes — no withdrawal fees beyond Polygon network gas. Kalshi settles in USD via CFTC clearance, Betfair in account currency net of commission, Manifold in play-money mana with no cash-out.
