**Trader sentiment clusters tightly around 27–29°C for Singapore’s August 25 minimum temperature, reflecting modest forecast uncertainty in an otherwise stable tropical regime.** Official outlooks and short-range models (including NEA/MSS guidance and station data through August 23) show prevailing southwest monsoon southeasterly flow, with most nights remaining warm and humid above 27°C. Recent August minima have typically ranged 26–28°C, with the lowest so far at 26.0°C on the 17th amid localized showers. For the 25th, models indicate overnight/early-morning readings near 27–28°C (roughly 81–83°F), with partly cloudy skies and a 30–40% thunderstorm chance that could limit nocturnal radiative cooling or briefly enhance it via evaporative effects. Key differentiating factors include cloud cover and timing of any showers (clearer intervals favor slightly lower minima near 27°C), surface wind speeds (light/calm conditions allow greater boundary-layer cooling), and dew-point levels (persistently high humidity near 75°F curbs the drop). Below-average rainfall so far this fortnight has kept conditions drier and slightly warmer than climatology, while the absence of strong cold-air intrusions or major model shifts keeps extremes (26°C or below, or 30°C+) at lower implied odds. Updated forecasts and any late-day convective activity on the 24th–25th remain the primary near-term catalysts for small probability adjustments.
