Drier conditions expected across Singapore in the first half of August, driven by a developing El Niño and positive Indian Ocean Dipole, have shifted trader consensus toward 32–33°C as the most likely daily maximum on August 10. These large-scale patterns suppress rainfall and cloud cover, increasing solar insolation and surface heating while reducing evaporative cooling from showers. Meteorological Service Singapore outlooks and recent observations near 32°C align with this range, though afternoon convection typical of the southwest monsoon introduces uncertainty that keeps 32°C and 33°C probabilities closely matched at 46.5% and 41.0%. Historical August maxima average near 31°C but frequently reach 33–34°C under similar dry spells, with official forecasts highlighting potential for brief warm, humid nights above 27°C. Updated model runs closer to the date will refine exact thresholds.
