Current forecasts from multiple meteorological sources indicate Manila's overnight low on September 12 will settle near 25–26°C, aligning with the market's strong 90% implied probability for that outcome. Persistent high humidity near 85–90%, light variable winds under 5 knots, and extensive cloud cover from the ongoing monsoon pattern limit radiative cooling, keeping minimum temperatures close to the seasonal tropical baseline of 25–26°C. Recent model runs show no significant cool-air intrusions or clear-sky episodes that would drive readings to 24°C or below, while the absence of extreme daytime heating caps the chance of an anomalously mild night above 27°C. Traders appear to be weighting official guidance from agencies tracking these stable conditions.
