NEA's April 1 fortnightly outlook forecasts daily maximum temperatures of 33–35°C across Singapore's first half of April amid inter-monsoon onset, with thundery afternoon showers on most days potentially extending evenings, yet trader consensus favors 32°C at 39.5% implied probability over 31°C (30.5%) and 33°C (19.5%) due to uncertainty in cloud coverage suppressing peaks. Equatorial insolation and urban heat island effects drive baseline highs near 32°C historically for April, but light variable winds promote cumulus build-up that curbs solar heating if showers arrive early afternoon; patchy or delayed rain enables NEA-projected spikes above 35°C on clearer days, as seen in late March's 35.4°C record. Daily NEA updates through April 5 will refine model consensus on shower timing and extent.
