**Official forecasts from PAGASA and global models such as GFS project a daytime high near 30–33°C for Manila on September 26, 2026, under partly cloudy skies with light to moderate southwest winds and scattered showers possible.** This aligns with late-September climatology, when average highs reach about 31–32°C amid the southwest monsoon, high humidity, and frequent afternoon convection that caps extreme heating. Ensemble guidance shows limited potential for stronger warming without clear skies or suppressed rainfall, keeping 37°C+ outcomes as lower-probability outliers consistent with rare historical September peaks. Trader consensus, reflected in the 52.5% implied probability for 33°C, incorporates these stable atmospheric conditions and the absence of tropical cyclone influences or unusual ridging that could elevate temperatures. Updated model runs through the morning of September 26 will provide the final resolution criteria for the highest recorded temperature.
