Persistent southwest monsoon flow and extensive cloud cover over Metro Manila are moderating overnight radiative cooling, supporting minimum temperatures near 26–28°C for August 24. Official PAGASA guidance and multiple model runs indicate scattered showers and high humidity that trap heat, limiting the typical seasonal drop toward 24–25°C. Recent station observations show overnight lows holding at 27–28°C amid similar conditions, while any brief clearing could allow brief dips toward 25°C. With resolution hinging on the single lowest hourly reading, traders weigh the monsoon’s steady influence against model spread in boundary-layer moisture and wind, producing closely matched probabilities across the 24–28°C range and a notable share on 31°C or higher if cloud cover remains unbroken.
