Recent Hong Kong Observatory forecasts and model consensus point to a transition from active southerly flow and thunderstorms on August 26–27 toward sunnier intervals with a few showers on the 28th, keeping overnight minimum temperatures uncertain amid high humidity and sea surface temperatures near 26–27°C. Persistent cloud cover or localized rain could enhance radiative cooling toward 26°C, while clearer skies and subsidence influences from Tropical Cyclone Saudel may limit drops closer to 28°C. These variables create the tight clustering of trader-implied odds around 26–28°C, as small shifts in timing or intensity of showers can alter the daily low by 1–2°C before resolution.
