Trader consensus overwhelmingly favors a highest temperature of 33°C in Singapore on March 20, anchored by the National Environment Agency's (NEA) precise forecast models showing a daytime peak under partly cloudy conditions with light showers and moderate sea breezes limiting insolation. Historical March data from Changi station averages 32.8°C highs, with 33°C as the modal outcome in 60% of recent years absent heat dome signals, corroborated by ECMWF and GFS ensembles converging on stable thermodynamics and low convective available potential energy (CAPE). Realistic challenges include an abrupt clearing of clouds boosting solar heating or urban heat island amplification during low-wind lulls, potentially nudging to 34°C, though upper-air ridging and humidity suppress extremes above 35°C.

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.
