Trader sentiment clusters tightly around 30–31°C outcomes, reflecting Meteorological Service Singapore (MSS) forecasts of frequent afternoon thundery showers under emerging inter-monsoon conditions, which often cap daily maximum temperatures through cloud cover and precipitation despite a stated range of 33–35°C. Early morning readings today hovered at 25.8–29.2°C, with solar heating building toward mid-afternoon peaks, but 65–95% rain probabilities introduce uncertainty—early widespread showers could limit highs to 30°C, while delayed convection might allow 32°C. April climatology averages ~31.7°C highs mid-month, aligning with this market-implied range; watch MSS hourly updates for real-time station data as resolution nears evening.
