Trader consensus on Polymarket heavily favors 33°C (37.5%) and 34°C (31.0%) as Singapore's highest temperature on March 25, driven by the National Environment Agency's (NEA) latest forecast predicting fair mornings with afternoon thundery showers and peaks near 33°C, corroborated by ECMWF and GFS models showing similar ranges. Singapore's equatorial climate during the inter-monsoon transition amplifies heat via high solar insolation and urban heat island effects, but convective showers often cap maxima by increasing cloud cover and humidity. Differentiation hinges on shower timing—earlier onset favors 33°C by suppressing peaks, while delays could push to 34°C amid sea breeze moderation; historical March 25 highs average 32-33°C with rare 35°C outliers amid low wind shear.
