Trader consensus on Polymarket implies a highest temperature around 31–33°C for April 5 in Singapore, with 32°C leading at 34%, 31°C at 30%, and 33°C at 23%, reflecting tight uncertainty amid the Meteorological Service Singapore's (MSS) April 1 fortnightly outlook forecasting daily maximums of 33–35°C through April 15 under emerging inter-monsoon conditions. This outlook anticipates afternoon thundery showers on most days—driven by light, variable winds and sea breeze convergence—potentially capping peak heating around 2–4 p.m. if clouds build early, though less coverage could push toward 35°C+ as seen in recent March highs exceeding 35°C during dry spells. Differentiating factors include shower timing, cloud fraction, and urban heat island effects versus coastal stations; watch MSS daily updates for refined model guidance as resolution nears.
