Trader consensus favors 32°C at 38.5% implied probability, edging out 33°C at 29%, driven by Singapore Meteorological Service forecasts indicating a daytime high near 32°C under partly cloudy skies with afternoon thundery showers during the inter-monsoon transition. Historical March data from Changi station shows average peaks of 32°C, but urban heat island effects and elevated sea surface temperatures around the equator boost potential for 33°C if showers delay. Model ensembles like ECMWF and GFS diverge slightly on cloud cover timing—key differentiator—with minimal wind shear allowing heat accumulation, though high humidity caps extremes above 34°C (8%). Final resolution hinges on official airport observations.

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.
