Drier southwest monsoon conditions prevailing over Singapore, as highlighted in the National Environment Agency's July 31 outlook, form the main driver behind the near-even market split between 32°C and 33°C for August 7. Fair and occasionally windy weather is expected to limit cloud cover and rainfall that normally cap afternoon peaks, pushing daily maxima toward 33–34°C—above the long-term August average near 31°C. AccuWeather guidance shows a seasonal range of 28.8–33.7°C, underscoring model sensitivity to localized thundery showers or subsidence strength. Traders weigh these factors against the narrow historical variability and potential for brief convective cooling, keeping probabilities for 34°C or higher low while concentrating implied odds on the 32–33°C band.
