Recent forecast models, including GFS guidance and PAGASA outlooks, point to partly cloudy to cloudy skies with isolated thunderstorms over Metro Manila on September 30, driven by the intertropical convergence zone and prevailing easterly flow. These conditions typically cap daytime maxima near 32–34°C through cloud cover and localized cooling from showers, consistent with late-September climatology where historical highs average around 30–31°C. High humidity near 70–85% and light winds further moderate peaks, though brief clearing could allow brief spikes toward 35°C. Model consensus shows limited disagreement on intensity, with resolution hinging on afternoon convective timing; updated PAGASA briefings and real-time observations will refine the outlook ahead of market close.
