Traders overwhelmingly back 33°C (43.5% implied probability) as Singapore's highest temperature on March 22, driven by the National Environment Agency's (NEA) latest forecasts indicating peaks of 32-34°C amid the lingering inter-monsoon period's clear skies and warm sea surface temperatures around 30°C. This equatorial city's urban heat island effect and minimal cloud cover—forecast at under 20%—amplify daytime highs, consistent with March climatology where averages hit 32.2°C but recent days have trended 1-2°C warmer due to weak easterly winds. ECMWF and GFS models converge on 33°C as the modal outcome, with low rain chances (10-20%) reducing cooling risks; historical data shows March 22 peaks at 32-34°C in 70% of recent years, positioning 32°C (32%) and 34°C (12.5%) as strong contenders while extremes fade.
