Recent PAGASA outlooks point to a 30–32°C high in Metro Manila on August 10 under the southwest monsoon, with 60% rain probability that favors cloud cover and reduced solar heating. This keeps implied odds centered on 29–30°C, consistent with the seasonal average maximum near 31°C while monsoon moisture and scattered thunderstorms introduce downward bias versus clearer-sky scenarios. Ensemble guidance shows limited model spread for peak afternoon readings, though timing of convective activity could shift the daily maximum by 1–2°C. Traders weigh these official forecasts and climatological baselines as the primary drivers ahead of final observational data.
