Singapore's tropical maritime climate under prevailing southwest monsoon conditions typically produces overnight minimum temperatures of 25–28°C, with recent official outlooks from the Meteorological Service Singapore noting most nights remaining above 27°C amid localized thundery showers and high humidity. Current forecasts from multiple models indicate an early-morning low near 27–28°C on August 28, supported by partly cloudy skies, light southeast winds, and dew points around 24–25°C that limit radiative cooling. The near-even market split between 27°C and 28°C reflects uncertainty in exact overnight cooling rates and any brief shower activity, while lower outcomes like 25°C carry lower implied probability given the warm baseline and lack of strong frontal influences. Updated model runs and official minimum readings later in the evening will likely resolve the close contest.
