Trader sentiment clusters tightly around 32–34°C for Singapore's March 23 peak temperature, driven by the National Environment Agency's (NEA) latest forecast projecting a high of 33°C amid persistent above-normal warmth from the fading El Niño influence. This inter-monsoon period typically sees March highs averaging 32–33°C historically at Changi Airport, but recent days have spiked to 34°C due to reduced cloud cover and weak sea breezes delaying afternoon thunderstorms. Differentiating factors include solar insolation intensity boosting daytime heating and urban heat island effects in the city-state, with model ensembles like ECMWF showing slight divergence—favoring 33°C as consensus—while any early convection could cap at 32°C or push to 34°C if suppressed. Upcoming hourly updates will sharpen resolution odds.

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.
