Singapore’s equatorial climate features persistently high humidity and minimal seasonal temperature swings, with daily maxima typically shaped by afternoon convective showers that limit peak heating. Recent model guidance points to partly cloudy conditions and light winds on May 19, supporting a most-likely range of 32–33 °C measured at official stations. Small differences in cloud timing, sea-breeze strength, or localized thunderstorm development can easily shift the observed high by one degree, which explains the tight market spread between the two leading outcomes. Updated forecasts from the Meteorological Service Singapore and fresh satellite imagery expected within the next 48 hours will refine these variables ahead of the market close.

This market will resolve to the temperature range that contains the highest temperature recorded at the Singapore Changi Airport Station in degrees Celsius on 19 May '26.
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.Singapore’s equatorial climate features persistently high humidity and minimal seasonal temperature swings, with daily maxima typically shaped by afternoon convective showers that limit peak heating.
