Official observations from Singapore's Meteorological Service (under NEA) at Changi Airport station—the market's resolution source—confirm the daily maximum temperature reached exactly 30°C on May 8 amid persistent thundery showers and heavy cloud cover that suppressed daytime heating. Network-wide peaks hit 31.8°C at inland sites like Tengah around 1 p.m., but Changi, exposed to sea breezes and 48.6 mm of rainfall, stayed cooler, aligning with inter-monsoon patterns favoring convective suppression over typical May highs of 33–35°C. Trader consensus at 100% reflects this verified data as of evening, with minimal risk of revision given the day's close. Only an anomalous late-evening spike or post-audit adjustment from automated instruments could challenge it, though historical precedents show such events rare below 95% certainty. Final daily bulletin expected soon.
