Traders are closely split on Singapore's highest temperature on March 25, with 33°C (35.5%) edging 34°C (30.5%) amid the latest NEA forecast projecting a peak of 33-34°C under partly cloudy skies with possible afternoon showers. This tight race reflects ensemble model consensus from ECMWF and GFS, showing a 1-2°C spread due to urban heat island amplification in the city-state and variable sea breeze timing, which can cap peaks below 35°C (20.5%). Historical March 25 highs at Changi Airport average 32.5°C but have hit 35°C in El Niño years like 2024, heightening uncertainty as traders weigh thunderstorm suppression against radiative heating. Resolution hinges on official NEA-measured max at the airport station.

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.
