Recent drier conditions across Singapore, following a wet July and reinforced by a strengthening El Niño with Niño-3.4 anomalies exceeding +2°C, have supported elevated daytime maxima near 33–34°C. National Environment Agency outlooks and regional models highlight fair, occasionally windy skies that reduce cloud cover and enhance solar heating, though typical equatorial humidity of 70–80% and scattered afternoon convection introduce variability in peak readings. Historical August highs average 31°C, with recent observations reaching 32–34°C under similar patterns. Trader sentiment reflects this narrow uncertainty band, as minor shifts in steering flow or shower timing on August 19 could differentiate outcomes between 31°C and 34°C.

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.
