Trader sentiment favors 33°C at 36% implied probability, edging out 34°C at 29%, driven by the latest ensemble forecasts from Singapore's Meteorological Service and global models like ECMWF and GFS, which converge on peak daytime highs of 33-34°C under dominant subsidence and weak monsoon influences. Differentiating factors include subtle variations in low-level wind shear and sea breeze timing—lighter southerlies could allow urban heat island effects to push toward 34°C, while any afternoon cumulus buildup might cap it at 33°C—as seen in recent dry spells with minimal rainfall. Historical March 25 averages hover around 32°C, but lingering El Niño warmth adds upside risk, keeping 35°C viable at 17.5%; traders eye tomorrow's 24-hour outlook for resolution shifts.
