Recent drier conditions forecast by Singapore's National Environment Agency for the first half of August, driven by the southwest monsoon, have elevated the likelihood of clearer skies and reduced rainfall, supporting higher maximum temperatures through increased solar insolation and less evaporative cooling. Equatorial climatology keeps daily highs tightly clustered near 31°C historically, with urban heat effects and light winds limiting extremes, though model runs show modest variability around this baseline. Trader consensus favoring 31–32°C reflects alignment with these patterns and official guidance, while lower probabilities for 33°C or above account for persistent humidity and any late-day convection that could cap peaks. New observational data from the Meteorological Service Singapore on August 16 will resolve the market.
