Trader consensus on Polymarket splits evenly between 32°C and 33°C as Singapore's highest temperature on March 28, driven primarily by the National Environment Agency's (NEA) latest 24-hour forecast projecting a peak of 33°C amid mostly clear skies and light winds. Equatorial heat persistence, amplified by urban heat island effects in the city-state, favors these upper-30s outcomes, with historical March maxima averaging 32.2°C but recent days hitting 33-34°C under similar low-humidity conditions. Differentiation hinges on afternoon sea breeze strength: stronger onshore flows could cap at 32°C via evaporative cooling, while stagnant air and solar insolation push toward 33°C, as implied by ensemble models showing minimal thunderstorm risk. Upcoming NEA updates at 12z could shift odds.
