Recent PAGASA guidance and ensemble forecasts point to a peak near 32°C on August 21 in Manila, with the spread among 31–33°C reflecting uncertainty in afternoon convective timing and cloud cover under the southwest monsoon. An intensifying El Niño is producing drier-than-average regional conditions that can allow stronger solar heating on clearer intervals, yet localized showers and high humidity often cap daily maxima in the urban heat-island environment. Traders weigh the balance between these short-term model runs—updated daily by the National Meteorological and Hydrological Services—and climatological baselines showing typical August highs of 30–32°C, with resolution hinging on the precise 24-hour maximum reported by official Manila stations.
