Trader consensus on Polymarket has locked in 100% implied probability for a highest temperature of 33°C at Singapore's Changi Climate Station—the market's official resolution source—reflecting National Environment Agency (NEA) observational data confirming this peak amid typical April warmth averaging 32°C daily maxima. Real-time monitoring throughout April 29 showed temperatures topping out at 33°C before afternoon thundery showers and partly cloudy conditions suppressed further rises, aligning with NEA forecasts of 25–34°C highs influenced by seasonal southwest monsoon onset and urban heat island effects moderated by humidity above 60%. While inherent sensor precision and final data validation carry minimal uncertainty, a rare late-day heat burst or post hoc measurement adjustment could theoretically challenge this, though traders see negligible risk as the day concludes.

This market will resolve to the temperature range that contains the highest temperature recorded at the Singapore Changi Airport Station in degrees Celsius on 29 Apr '26.
The resolution source for this market will be information from Wunderground, specifically the highest temperature recorded for all times on this day by the Forecast for the Singapore Changi Airport Station once information is finalized, available here: https://www.wunderground.com/history/daily/sg/singapore/WSSS.
To toggle between Fahrenheit and Celsius, click the gear icon next to the search bar and switch the Temperature setting between °F and °C.
This market can not resolve to "Yes" until all data for this date has been finalized.
The resolution source for this market measures temperatures to whole degrees Celsius (eg, 9°C). Thus, this is the level of precision that will be used when resolving the market.
Any revisions to temperatures recorded after data is finalized for this market's timeframe will not be considered for this market's resolution.Trader consensus on Polymarket has locked in 100% implied probability for a highest temperature of 33°C at Singapore's Changi Climate Station—the market's official resolution source—reflecting National Environment Agency (NEA) observational data confirming this peak amid typical April warmth averaging 32°C daily maxima.
