Persistent southwest monsoon flow, reinforced by a nearby low-pressure area, is sustaining widespread cloud cover, scattered thunderstorms, and moderate-to-strong southwesterly winds over Metro Manila through August 30. These conditions limit nocturnal radiative cooling, keeping minimum temperatures elevated compared with clearer-sky baselines. PAGASA outlooks and consensus model guidance indicate overnight lows centered in the 25–28 °C range, with the precise daily minimum hinging on the timing and intensity of rain showers that can further suppress temperature drops. Historical August climatology for Manila shows typical minima near 25–26 °C under similar monsoon regimes, supporting the tight clustering of market-implied probabilities around 24–27 °C while leaving room for modest shifts if convective activity or wind patterns evolve in the final model runs.
