**Trader consensus centers on a 27°C minimum for Singapore on August 21, 2026, reflecting official forecasts of nighttime lows near 26–27°C under prevailing southwest monsoon conditions.** Persistent high humidity, light southeasterly winds, and limited cloud cover overnight restrict radiative cooling, keeping temperatures above the August climatological average minimum of 25.3°C. Recent observations from early August showed many nights remaining above 27°C amid below-average rainfall and maximums reaching 33–34°C, while current model runs from sources like the Meteorological Service Singapore project fair, occasionally windy conditions with overnight readings around 27°C. This positioning explains the dominant 62.5% implied probability on 27°C and secondary support near 26°C, as any unexpected clearer skies or reduced moisture could allow modest further cooling toward 25°C but are not currently favored.

This market will resolve based on the lowest 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 lowest temperature recorded at the Singapore Changi Airport Station in degrees Celsius on 21 Aug '26.
The resolution source for this market will be information from Wunderground, specifically the lowest 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.
Revisions to temperatures recorded within this market's timeframe will be considered until the first datapoint for the following date has been published, after which any alterations will not be considered.**Trader consensus centers on a 27°C minimum for Singapore on August 21, 2026, reflecting official forecasts of nighttime lows near 26–27°C under prevailing southwest monsoon conditions.** Persistent high humidity, light southeasterly winds, and limited cloud cover overnight restrict radiative cooling, keeping temperatures above the August climatological average minimum of 25.3°C.
