Highest temperature in Manila on July 11?

Platform comparison

Market context

Manila faces a sweltering July 11, 2026, with the Ninoy Aquino International Airport Station set to record its peak daily temperature in degrees Celsius. The market resolves based on the highest reading at this specific station, sourced from Wunderground history, while the crowd currently assigns zero probability to the YES outcome, suggesting a strong consensus that the temperature will fall outside the defined range.

Historical July data frames this improbability, as Manila typically sees daytime maximums around 31°C, with long-term averages rarely exceeding 32°C despite high humidity [3]. While recent heat indices in Metro Manila have approached dangerous levels of 44°C, these represent apparent temperatures influenced by humidity rather than dry-bulb readings at the airport station [2]. The divergence between Polymarket’s decimal implied probability and Kalshi’s or Betfair’s decimal odds structures becomes critical here; a 0% implied probability on Polymarket implies a near-certain NO, whereas a book like Smarkets might list this as 100/1 odds, reflecting the same sentiment through a different pricing mechanism.

Traders should monitor Pagasa’s real-time forecasts for tropical storm passages, which average 1.6 days in July and could suppress peak temperatures significantly [3]. The settlement dependency on Wunderground’s specific airport data means local urban heat spikes in Baler or Aurora, which may reach 46°C, will not influence the outcome [2]. Fee structures also vary notably across platforms; while Polymarket often charges lower fees for crypto users, Kalshi’s KYC requirements and Betfair’s commission model alter the effective payout for this binary weather event, making the choice of book a material factor in risk exposure.
