Highest temperature in Manila on July 11?

Platform comparison

Market context

Manila faces its wet season peak on 11 July 2026, when heavy rainfall and high humidity typically suppress daytime highs to around 31°C at Ninoy Aquino International Airport. Historical averages for July show maximums rarely exceeding 32°C, with the wet season (June–October) averaging 26–31°C compared to the dry season’s 28–32°C[2][4]. The current 0% implied probability for any extreme heat outcome aligns with this pattern; Manila’s hottest months are March and April, not July, and record highs in the city have occurred in the dry season, not during monsoon rains[2].

Traders should monitor PAGASA’s daily extended outlook for Metro Manila, which forecasts a 25–29°C range for 11 July with unspecified rain chances[6]. While recent heat-index warnings have reached 44°C in surrounding areas like Aurora, these reflect “feels like” temperatures driven by humidity, not actual air temperature at the airport station[3][10]. The key dependency is whether tropical storms—averaging 1.6 per July in Manila—pass nearby, as their cloud cover and rain further limit solar heating[4]. On platform comparison, Polymarket displays this as 0% implied probability, whereas Kalshi would show decimal odds of infinity (no trade), and Betfair/Smarkets might list it as 1.00 decimal with no liquidity, reflecting divergent fee structures and KYC thresholds that affect market depth on low-probability weather events.
