Trader consensus places the highest probability on a 32°C high for Singapore on August 6, with 31°C and 33°C close behind, reflecting the narrow range typical of the city-state’s equatorial climate during the southwest monsoon period. Daily maxima are shaped by persistent high humidity, sea-surface temperatures near 30°C, and afternoon convective clouds that limit radiative heating. Short-term forecast models show modest day-to-day variability driven by the strength of the monsoon flow and any passing rain bands, producing the observed 41 %–32 %–24.5 % distribution across the three leading outcomes. Official guidance from the National Environment Agency and regional ensembles will tighten these probabilities as the date approaches.
