Recent drier conditions under prevailing southwest monsoon flows have positioned Singapore for daytime maxima slightly above the long-term August average of 31°C, with official guidance from the National Environment Agency highlighting 33–34°C potential on many days in the first fortnight. Short-range model consensus and extended forecasts for August 18 cluster around 32–33°C, reflecting moderate humidity, occasional thundery showers, and limited intensification potential that caps extremes. This scientific context drives the market's strong weighting toward 32°C and 33°C outcomes, while lower probabilities for 34°C or higher reflect the narrow window for significant departures given current steering patterns and moisture levels. Updated NEA briefings and model runs in the next 24–48 hours will provide key inputs for traders.

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 18 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.
