Recent forecasts from Singapore's National Environment Agency and models like those referenced by the NEA indicate prevailing southwest monsoon conditions with drier air and mostly clear to partly cloudy skies through late August, typically supporting minimum temperatures of 25–27°C. These align with climatological baselines of 24–26°C for the month, where radiative cooling under reduced cloud cover and light southeasterly winds can occasionally dip readings lower. The elevated market-implied probability on 21°C or below reflects trader assessment of model spread and potential for enhanced nocturnal cooling from any unexpected moisture surge or wind shift, while probabilities clustering around 25–28°C capture the most likely range based on current observational trends and short-range guidance. Upcoming NHC-style regional updates and local station data over the next 48 hours will likely refine these odds as land-sea breeze interactions and humidity levels are monitored.
