Recent forecasts from regional models indicate overnight lows in Manila on September 14 will likely range from 24–25°C amid persistent cloud cover and scattered showers tied to the southwest monsoon. High humidity near 80–90% and light variable winds limit radiative cooling overnight, keeping minimum temperatures close to climatological norms for mid-September. Official guidance from PAGASA highlights continued wet conditions with no major tropical systems expected to alter steering patterns or intensify rainfall in the immediate term. Traders monitor updated model runs for any shifts in the low-level wind field or timing of convective activity, as these can influence the precise minimum recorded at standard observation sites. Historical data show September nocturnal temperatures rarely deviate more than 1–2°C from these baselines absent unusual synoptic features.
