Traders favor 33°C at 33.5% implied probability, aligning with the Meteorological Service Singapore's latest forecast of a 33°C high amid partly cloudy skies and afternoon thundery showers on March 22. This edges out 32°C (21.5%) and 34°C (18%), reflecting high uncertainty from convective activity that could cap peaks via cloud shading or allow urban heat island effects to push 35°C+ (14.5%) during clear spells. Recent days saw 34°C highs under lingering El Niño warmth, but sea breezes and humidity introduce volatility; historical March averages hover at 32°C, with outcomes hinging on morning insolation versus rain onset timing.
