Trader sentiment on Singapore's highest temperature for March 20 hinges on ensemble forecasts from the Meteorological Service Singapore and global models like ECMWF and GFS, which cluster tightly around 32–34°C amid persistent inter-monsoon warmth and low wind shear. Leading odds favor 33°C (30.5%) over 32°C (28%) and 34°C (26.5%) due to recent model runs indicating delayed sea breeze onset—potentially allowing afternoon peaks to nudge higher—balanced against urban heat island amplification at Changi station versus risks of isolated thundery showers capping convection-driven highs. Historical March maxima average 32.1°C with a 1–2°C standard deviation, underscoring razor-thin differentiation from humidity-laden air masses and subtle cloud cover variability. Upcoming MSS updates at 6 AM/PM SGT could shift probabilities.

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.
