Recent PAGASA forecasts for Metro Manila point to a 32°C high on August 23 amid the southwest monsoon, with 60% rain chance and typical August conditions featuring highs near 31°C, high humidity above 80%, and frequent cloud cover that often caps peaks. Trader sentiment reflects this baseline, with 30–32°C outcomes commanding the largest shares because monsoon-driven showers and variable steering patterns can easily suppress maxima by 1–2°C or allow brief clear spells to push readings higher. Key uncertainties include short-term model shifts in rainfall timing, urban heat effects, and any strengthening of the monsoon flow, all of which will be clarified by updated agency guidance within the next 48 hours.
