Singapore's equatorial climate produces typical August daily maxima near 31–32°C, with recent National Environment Agency guidance and subseasonal outlooks highlighting drier Southwest Monsoon conditions and above-normal temperatures across the Maritime Continent through late August, influenced by a developing El Niño. Extended forecasts for 20 August converge on a high around 32°C under partly cloudy skies with isolated showers, consistent with model consensus and historical August averages of 88°F (31°C). These factors, combined with limited day-to-day variability in the region, underpin the strong market weighting toward 32°C while leaving modest room for 33°C if localized heating intensifies.

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 20 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.
