Trader consensus heavily favors 33°C (44.5% implied probability) as Singapore's highest temperature on March 23, driven by the National Environment Agency's (NEA) latest forecast indicating afternoon highs near 33°C amid persistent inter-monsoon heat and low rainfall. Recent observations show daily maxima hovering at 32-34°C over the past week, with urban heat island effects amplifying temperatures in built-up areas like Changi. El Niño's lingering influence has elevated March baseline highs above the 31-32°C historical average, though occasional thundery showers could cap peaks below 34°C (22.5%). NEA heat stress metrics remain below warning thresholds, tempering extremes above 35°C (6.7% combined), positioning 32-34°C as the most probable range per ensemble models.
