Singapore has a warm tropical equatorial climate with consistent heat and humidity throughout the year. April brings typical daily highs between 32 and 34 degrees Celsius as the dry season transitions toward the monsoon period. A maximum temperature of exactly 26 degrees Celsius on April 20 would represent a substantial weather departure—such a cool day would require extensive cloud cover, significant rainfall, or an anomalous weather system blocking normal solar heating. The market currently shows zero percent odds on YES, reflecting trader assessment that this scenario is exceptionally unlikely. The price structure indicates near-universal expectation of normal tropical weather, with temperatures projected substantially above the 26-degree threshold. Market depth and volume suggest stable consensus with minimal conviction shifts expected. Official settlement will be determined by the highest temperature recorded by Singapore's meteorological service on April 20, 2026, measured at the designated monitoring station. The market resolves at midnight UTC on that date using official national weather records.
