Persistent cloud cover and high humidity from the southwest monsoon (habagat) are the dominant factors keeping Manila's minimum temperature on August 30 tightly clustered around 24–26°C. Thick stratiform clouds and frequent thunderstorms suppress radiative cooling overnight, while dew points near 24°C set a firm floor on how far air temperatures can fall. Current model consensus from sources like PAGASA-aligned runs and global ensembles shows overnight lows stabilizing in this narrow band, with only modest day-to-day variability from wind shifts or rainfall timing. The closely matched market prices around 24–26°C reflect this limited range, as traders weigh the low probability of either stronger subsidence (pushing lows toward 22–23°C) or clearer breaks that could allow slightly warmer minima. Updated PAGASA guidance and next model cycles tomorrow morning remain the key near-term catalysts.
