Official National Environment Agency (NEA) observations from the Changi Meteorological Station confirm Singapore's highest temperature reached exactly 33°C on May 3, 2026, driving the 100% market-implied probability for this outcome. Amid inter-monsoon conditions with light winds and frequent afternoon thundery showers, cloud cover and precipitation capped daytime heating despite pre-event forecasts of 33–35°C daily maximums from NEA's fortnightly outlook. This aligns with May climatology, where Changi highs typically average 31–33°C. With data now finalized per NEA protocols, trader consensus reflects virtual certainty; only an improbable post hoc revision from quality control—such as a late-recorded sensor reading—could challenge it, though historical precedents show such adjustments are rare below 0.1°C.
