Highest temperature in Kuala Lumpur on August 16?

Platform comparison

Market context

On 16 August 2026, the highest temperature recorded at Kuala Lumpur International Airport will fall into one of several defined ranges. The market resolves using the Daily Observations table from Weather Underground rather than summary figures, a distinction that matters when intraday spikes occur. Settlement occurs at 12:00 UTC on that date, creating a hard deadline for temperature data capture across different platforms.

Kuala Lumpur's August climate is remarkably consistent. Historical records show daily highs cluster between 32–34°C, with extreme readings above 35°C occurring in fewer than 5% of August days over the past two decades. The 0% crowd probability suggests traders are either pricing in confidence that the market's upper threshold sits above realistic August maximums, or that the resolution methodology—specifically the Weather Underground Daily Observations table requirement—introduces sufficient friction that participants view the outcome as predetermined. This contrasts with how Betfair and Smarkets typically handle weather markets, where decimal odds more transparently reflect tail-risk pricing on outlier temperatures.

Malaysia's monsoon patterns and urban heat island effects around the airport remain the primary variables. The Southwest Monsoon dominates August, typically suppressing extreme heat through cloud cover and moisture, though occasional high-pressure systems can drive temperatures toward 35°C. No scheduled weather events or climate announcements are expected to alter August 2026 conditions materially. Traders comparing this market across Polymarket, Kalshi, and traditional bookmakers should note that fee structures and liquidity depth vary significantly; Kalshi's regulatory framework in the US may restrict certain temperature ranges from trading, whilst Betfair's commission model affects effective odds differently than Polymarket's AMM pricing.
