**Official measurements from Singapore's National Environment Agency (NEA) confirm the highest temperature on March 26 hit 33°C at primary stations like Changi, anchoring trader consensus at a 99.8% market-implied probability for this outcome.** The city-state's equatorial climate delivers reliable daily highs of 31–34°C in March's inter-monsoon season, with sea breezes and urban heat effects capping extremes amid typical humidity above 80% and minimal wind shear. Pre-event forecasts from global models like ECMWF and GFS converged on 32–33°C peaks under stable high-pressure conditions. Barring rare post hoc data revisions from secondary sensors—a scenario with negligible precedent—this positioning reflects ironclad observational evidence, with resolution imminent upon NEA finalization.

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.
