Recent forecasts from Singapore's Meteorological Service and global models indicate typical August minimum temperatures of 25–27°C driven by persistent high humidity, limited nocturnal radiative cooling under cloudy skies, and light winds amid the southwest monsoon. Official outlooks note drier daytime conditions with maxima near 33–34°C, but overnight lows remaining above 25°C in most runs, consistent with climatological baselines around 26°C. Model spread and potential for increased cloud cover or brief showers introduce uncertainty that supports the 40% market-implied odds on 21°C or below, while the clustering around 27–28°C reflects consensus expectations for stable tropical conditions. Updated NEA briefings and ensemble runs through August 23 will refine these probabilities ahead of resolution.
