Recent drier conditions under the prevailing southwest monsoon have driven afternoon maxima to 33–34°C on most days in early-to-mid August, consistent with National Environment Agency outlooks and observations reaching 34.9°C at Pulau Ubin on August 14. Short-range forecast guidance and historical analogs under similar trade-wind flow and reduced convective cloud cover favor a peak near 33°C on August 22, with limited potential for 35°C under unusually clear skies or 32°C if scattered showers develop earlier. Market-implied probabilities, led by 33°C at 59%, aggregate trader assessments of this narrow range ahead of official Meteorological Service Singapore readings.

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 22 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.
