Singapore’s National Environment Agency forecasts place daily maximum temperatures at 33–34 °C through mid-August under drier southwest-monsoon conditions reinforced by a developing positive Indian Ocean Dipole. This outlook aligns with climatological baselines for the period and current model consensus showing limited cloud cover and modest afternoon heating, supporting the market’s 100 % implied probability for a 33 °C peak. Official observations at Changi and other stations typically resolve these markets, and recent model runs have shown little deviation from the 33 °C threshold. A sudden increase in convective showers or thicker afternoon cloud decks could cap readings below this level, though such shifts remain unlikely given the prevailing atmospheric setup.
