Official observations from Singapore's Meteorological Service Singapore confirm the highest temperature reached 32.3°C at Tuas South by 11:35 a.m. on April 20, 2026, already surpassing the 32°C threshold amid strong solar heating during inter-monsoon conditions. This aligns with the month's pattern, where maximums exceeded 34°C on 12 of the first 15 days, peaking at 35.4°C, driven by light winds and persistent humidity amplifying urban heat island effects. Forecasts indicate a daily peak around 33°C despite afternoon thundery showers, reflecting model consensus for equatorial stability. Trader consensus at 100% implied probability reflects this locked-in observational data; only an unprecedented pre-noon measurement revision—highly improbable given standardized station protocols—could challenge it, with final NEA daily records expected post-midnight.
