**Drier southwest monsoon conditions are driving expectations for a peak temperature of 32–33°C in Singapore on August 13.** Official Meteorological Service Singapore (MSS) and NEA outlooks for the first half of August highlight fair, occasionally windy southeast-to-south flow with reduced cloud cover and only localized afternoon thundery showers, supporting daytime maxima of 33–34°C on most days. The 4-day forecast specifically lists 34°C for August 13 under fair skies, consistent with broader seasonal guidance that places typical highs in this range amid below-average rainfall. These conditions align with the market's heavy weighting toward 32°C (62.5%) and 33°C (30.5%), as traders weigh the balance between model guidance favoring the mid-30s and historical tendencies for recorded station maxima to settle slightly lower due to localized variability or brief shower timing. Recent El Niño and positive Indian Ocean Dipole signals reinforce the drier, warmer regime through the southwest monsoon period, though no abrupt forecast shifts have occurred in the past 48 hours to alter near-term probabilities. Updated model runs or overnight observations could still influence final resolution if showers develop earlier than expected.
