Trader consensus on Polymarket overwhelmingly favors 32°C as Singapore's highest temperature on April 26, 2026, with 100% implied probability, driven by official Meteorological Service Singapore observations showing a daytime peak of around 32°C at key stations like Changi Airport amid afternoon thundery showers over northern, western, and central areas. These showers reduced solar insolation and suppressed convective heating after midday peaks, aligning with equatorial climatology where daily maxima typically occur between noon and 3 p.m. under light easterly winds (5-15 km/h). Current evening readings near 28°C, post-peak heating window, solidify this positioning per NEA real-time data. A realistic challenge would require a late-reported revision exceeding 32.5°C at the resolving station, though unlikely given stabilized conditions and historical April baselines around 31-33°C.
