Recent official forecasts from Singapore's Meteorological Service and regional models indicate a daily maximum near 33°C for August 25, driven by typical southwest monsoon conditions with light winds, high humidity, and limited cloud cover that allow strong solar heating. Recent second-half August observations have consistently reached 33–34°C amid drier regional air masses, aligning with the market's heavy weighting toward 33°C while leaving room for 32°C or 34°C if convective showers develop earlier or steering patterns shift. Historical August baselines average 31–32°C, so current conditions reflect modest positive anomalies without extreme heat-wave signals. Traders monitor the final 24-hour model runs and NEA nowcasts, as afternoon thundershowers remain the key variable that could cap or elevate the peak by 1°C.
