The southwest monsoon (habagat) continues to dominate Metro Manila with persistent cloudy skies, scattered rains, and thunderstorms through August 18–19, moderating daytime heating and keeping maximum temperatures in a narrow 26–31 °C range according to PAGASA outlooks. This pattern suppresses peaks below the seasonal 31 °C average by limiting solar insolation and promoting evaporative cooling, which is why market-implied odds cluster tightly around 27–30 °C. Model consensus shows only modest day-to-day variability tied to the exact timing and intensity of convective cells, with no strong signals for either a clearer, hotter spell or heavier suppression that would push probabilities outside the current band. Updated forecasts on August 17–18 will be the key near-term catalysts for any shifts in trader positioning.
