Drier Southwest Monsoon conditions, reinforced by an emerging El Niño and positive Indian Ocean Dipole, represent the main driver keeping market-implied odds highest for 32°C (59%) and 33°C (31%) as Singapore’s peak temperature on August 13. These large-scale patterns suppress cloud cover and rainfall, favoring elevated daytime maxima in the 32–34°C range consistent with National Environment Agency outlooks and recent observations of 33.4°C on August 3 followed by 32–33°C readings. Equatorial humidity, urban heat island effects, and typical August climatology centered near 31°C highs add upward pressure, while model consensus on limited convection and forecast uncertainty limit probabilities for 34°C or above to under 5%. Official measurements from Meteorological Service Singapore stations will determine final resolution within this narrow band.

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 13 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.
