Official forecasts from Singapore's Meteorological Service Singapore and National Environment Agency project a daily maximum of 33°C on August 11 under persistent drier conditions and southeasterly flow during the first half of the month. These conditions, reinforced by developing El Niño and positive Indian Ocean Dipole influences, have suppressed rainfall and cloud cover, elevating temperatures above the typical August climatological maximum near 31°C. Recent observations from early August show peaks of 32–33.4°C, aligning with model consensus. The near-certain market-implied probability for 33°C reflects this strong observational and forecast alignment, though unexpected afternoon convection or thicker cloud build-up could still cap readings at 32°C or allow brief spikes toward 34°C before official station data finalize the outcome.

This market will resolve based on the highest temperature recorded in the 'Daily Observations' table on Weather Underground, not the figure displayed in the 'Day High & Low' summary section; in the event of any discrepancy between the two, the Daily Observations table shall be the primary resolution source not the Day High & Low section.
This market will resolve to the temperature range that contains the highest temperature recorded at the Singapore Changi Airport Station in degrees Celsius on 11 Aug '26.
The resolution source for this market will be information from Wunderground, specifically the highest temperature recorded for all times on this day for the Singapore Changi Airport Station, 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 until the first data point for the following date has been published on the resolution source.
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.
