Singapore's Meteorological Service anticipates a daily maximum near 32°C on May 17 under prevailing inter-monsoon conditions of light, variable winds and scattered afternoon thundery showers. These convective systems typically develop by early afternoon, curtailing peak solar heating and introducing short-term variability that keeps the market split between the 31°C and 32°C outcomes. Historical May climatology supports highs clustered around 31–32°C, with occasional excursions above 33°C possible only if showers arrive later or remain localized. Model consensus shows modest spread in timing and coverage of precipitation, sustaining uncertainty ahead of the next official update and final observations.
