Traders are closely split between 33°C (35%) and 32°C (34.5%) for Singapore's highest temperature on March 26, driven by the National Environment Agency's (NEA) latest forecast predicting a daytime high of 33°C under mostly fair skies with minimal cloud cover and light winds. Late March typically sees average highs around 32°C in Singapore's equatorial climate, but urban heat island effects and lingering El Niño warmth have pushed recent peaks higher, with 33°C recorded on similar dry days last year. Low humidity (60-70%) favors greater solar heating, while any afternoon sea breeze or isolated showers could cap it at 32°C—key uncertainties reflected in model ensembles from ECMWF and GFS showing tight spreads. Hourly NEA observations will resolve this by evening.
