Highest temperature in Kuala Lumpur on August 10?

Platform comparison

Market context

Kuala Lumpur’s maximum temperature on 10 August is usually in the low 30s Celsius, which makes **34°C** the key threshold for this market rather than an extreme heat event. August climate data and historical daily readings suggest typical highs around 30–31°C, with individual days in recent years often reaching 31–34°C and occasional spikes higher; that fits the current Polymarket pricing, where **34°C** is the dominant outcome at 90% and **35°C** sits at 10%.[1][5][6][9][11][17]

The present **0% YES** crowd view is best read as a platform-format effect rather than a statement that the event is impossible. On Polymarket, the quoted level is an implied probability; on Kalshi, contracts are usually shown in cents, while Betfair and Smarkets display decimal odds and apply different commission structures, so the same weather call can look materially different after fees and market-making spreads. Kuala Lumpur’s August weather also tends to be cloudier and rain-affected, but short-lived convection can still push the day’s peak temperature up into the mid-30s Celsius, especially if sunshine breaks out before storms develop.[3][8][16][18]

For traders, the main catalysts are the day-of forecast updates and the actual hourly observations that can confirm whether the airport station touches 34°C or pushes into 35°C before the settlement cut-off. Weather Underground’s **Daily Observations** table is the binding source here, so a discrepancy with any summary high/low display will not matter. At 8 August forecast points, Kuala Lumpur was already being marked around **89–92°F** with thunderstorms possible, and the market may stay pinned unless the final-day forecast shifts materially or the station records an early-afternoon heat spike.[3][8][14][16]
