**Current official forecasts from Taiwan's Central Weather Bureau and international models indicate overnight lows in Taipei on August 29 near 26–27°C under partly cloudy to rainy conditions with 60–70% storm chances.** High humidity (often 80–95%) and cloud cover limit radiational cooling in this humid subtropical climate, where typical late-August minimums average 25–26°C. Any persistent rain or thick cloud from residual moisture would trap heat and push the low toward 27°C or higher, while clearer breaks could allow slightly more cooling toward 25°C. The 22°C-or-below outcome remains unlikely without an atypical cold surge, which current steering patterns and model consensus do not support. Traders appear to weigh forecast spread and precipitation timing heavily, with the tight 27°C versus lower-bin odds reflecting uncertainty in exact overnight cloud and rain evolution ahead of resolution.
