Trader consensus assigns near-certainty to a highest temperature of 31°C at Singapore's Changi Airport station on April 21, 2026, backed by National Environment Agency (NEA) real-time observations showing this as the daily maximum amid afternoon thundery showers that capped heating after an early morning peak of 32.6°C elsewhere like Clementi. Inter-monsoon conditions, with persistent short-duration rain suppressing solar insolation, align with NEA advisories forecasting subdued highs below early April's 35.4°C extremes despite potential for 33-34°C. Historical April averages hover at 31-32°C, reinforcing positioning. Realistic challenges include rare data revisions from final NEA tallies, but protocols and late-day timing (post-11 pm updates) render shifts improbable.
