**Trader sentiment for Manila’s lowest temperature on September 2, 2026, centers on 27°C as the leading outcome (55.5% implied probability), reflecting broad model agreement on an overnight low near that value amid typical early-September monsoon conditions.** Forecasts from multiple sources, including hourly runs valid as of September 1, show temperatures bottoming out around 26–28°C (roughly 79–82°F) in the early morning hours of September 2, driven by persistent cloud cover, high humidity near 85–90%, and southwest monsoon flow that limits radiational cooling. Dew points remaining in the mid-20s°C sustain elevated nighttime readings, while scattered to widespread showers and thunderstorms—common during the peak rainy season—further moderate temperature drops. Historical September averages for Manila lows hover near 25°C, but current conditions and short-term guidance point slightly warmer. The clustered probabilities around 25–31°C (all near 45%) capture the inherent uncertainty in tropical overnight minima, where small shifts in timing of rain or wind can alter the exact low by 1–2°C. Outcomes below 24°C carry low odds (under 8%) because sustained clear skies or stronger northerly flow would be required to produce such cooling, which current atmospheric patterns do not support. Updated model runs and official agency guidance over the next 24 hours will be the key catalysts that could refine these market-implied odds.
