Meteorological Service Singapore observations at the official Changi climate station show a peak temperature of 32°C on May 5, 2026, as of late evening, fueling trader consensus at virtually 100% implied probability for that outcome amid $78K in volume. Inter-monsoon conditions brought afternoon thundery showers over many areas—recording up to 74mm at Sentosa—capping solar heating despite the fortnightly outlook's forecast of 33–35°C maxima on most days. High humidity (60–95%) and south-southeasterly winds further moderated intensities, aligning with equatorial climatology where May daily highs average 31°C. With sunset past and clouds persisting, realistic challenges like an overlooked midday spike at Changi are minimal, pending final daily validation.
