Trader consensus on Polymarket closely splits between 31°C (34.5%) and 32°C (31.5%) for Singapore's highest temperature on April 6, reflecting inherent uncertainty in short-term forecasts during the onset of inter-monsoon conditions. The National Environment Agency's (NEA) latest fortnightly outlook, issued April 1, projects daily maximums of 33–35°C across the first half of April despite afternoon thundery showers on most days, which can cap peaks through convective cooling and cloud cover. Differentiating factors include timing of showers—midday clearing favors 32°C or higher, while early convection tilts toward 31°C—against a climatological April average of 31°C and recent March heat (up to 35.4°C). Updated NEA 24-hour forecasts expected daily will sharpen model consensus on wind patterns and humidity-driven heat.
