The southwest monsoon, or habagat, remains the dominant driver shaping Manila's temperatures ahead of August 25, delivering persistent cloud cover, scattered showers, and elevated humidity that typically cap daytime highs near the seasonal average of 30–31°C. Official PAGASA guidance shows forecast maxima of 29–31°C for that date amid 60–90% rain probabilities, consistent with long-term climatology for the peak wet season. Recent low-pressure monitoring east of the Philippines has introduced minor uncertainty in steering flow and rainfall intensity, which could either enhance cooling through increased convection or allow brief sunny breaks to push readings slightly higher. Traders weigh these model consensus runs against historical analogs where monsoon surges have suppressed peaks by 1–2°C. Updated PAGASA and numerical weather prediction outputs over the next 48 hours will likely refine the implied probability distribution for the day's maximum.
