Singapore’s equatorial location under the southwest monsoon typically yields daily maximum temperatures of 31–32°C in mid-August, but an official NEA forecast for drier-than-average conditions through mid-month has shifted trader focus toward 33–34°C. An emerging moderate El Niño is reinforcing above-normal warmth and suppressing rainfall across the Maritime Continent, while the urban heat island effect can add 1–2°C locally. A confirmed 34°C reading at Sembawang on August 15 further supports the tilt toward the upper end of the normal range. Afternoon thundery showers and high humidity continue to cap extremes, keeping probabilities concentrated on 32°C and 33°C ahead of the next official station data.
