PAGASA forecasts indicate a southwest monsoon (habagat) will sustain cloudy skies and scattered rains over Metro Manila through August 19, moderating daytime highs to 29–31°C amid high humidity and limited solar insolation. This aligns with the climatological August average of roughly 31°C, though persistent monsoon flow and model consensus from recent runs favor values near the lower end of the typical 28–33°C range observed historically. No significant temperature anomalies or clear-sky periods are expected in the immediate forecast window, keeping trader focus on official updates and any last-minute shifts in monsoon intensity or steering patterns that could alter peak readings.
