Recent Singapore temperature forecasts and official outlooks position 32°C as the leading outcome for the August 19 daily maximum. A strengthening El Niño event, with Niño-3.4 anomalies exceeding +2°C, is driving warmer and drier regional conditions through mid-August, consistent with National Environment Agency guidance projecting most-day highs of 33–34°C during the first fortnight. Short-term models show cloud cover and showers moderating peaks near 31–32°C on the 19th, aligning with climatological August averages of 31.4°C but elevated by the current ENSO phase. Market-implied probabilities reflect this balance between persistent warmth and daily variability in equatorial convection and steering winds.

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 19 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.
