Short-range forecasts from regional models and official outlooks cluster around 32–33°C for Singapore’s maximum temperature on August 18, aligning with the market’s heavy weighting toward 33°C. A strengthening El Niño, with Niño-3.4 anomalies already exceeding +2°C, is reinforcing warmer and drier southwest monsoon conditions across the Maritime Continent, reducing cloud cover and supporting daytime heating near historical August maxima. The Meteorological Service Singapore and NEA advisories note prevailing fair and occasionally windy patterns likely to yield daily highs of 33–34°C through mid-August. Thunderstorm activity or increased humidity could cap readings at 32°C, while clearer skies or stronger subsidence might push isolated areas to 34°C, though model consensus keeps extremes below 10% probability. Official MSS station data on the day will determine resolution.
