This market will resolve to the temperature range that contains the lowest temperature recorded by NOAA at the Singapore Changi Airport Station in degrees Celsius on 27 Aug '26. The resolution source for this market will be information from NOAA, specifically the lowest reading under the "Temp" column for all times on this day, available here: https://www.weather.gov/wrh/timeseries?site=wsss If NOAA data is unavailable or missing for the observation period, Weather Underground will be used as the secondary resolution source. To toggle between Fahrenheit and Celsius, click the "Switch to Metric Units" button until the relevant table displays °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.
Recent forecasts and current conditions point to a likely overnight minimum of 25–26°C for Singapore on August 27, 2026, aligning with the closely matched market-implied odds (25°C at 38.8%, 26°C at 32.5%, 24°C at 25%). Singapore’s near-equatorial location produces stable tropical temperatures, with daily minima typically shaped by cloud cover, humidity, rainfall, and light winds that limit radiative cooling overnight. Official outlooks note above-normal temperatures persisting through August under southwest monsoon conditions, with localized thundery showers expected. The most recent recorded minimum (August 26) reached 25.4°C, and short-range models for the night of the 27th converge on lows near 25–27°C (roughly 77–81°F), depending on the extent of cloudiness and any showers that could either suppress cooling or enhance it through evaporation. The tight clustering around 24–26°C reflects model uncertainty in exact overnight radiative losses and boundary-layer mixing under partly cloudy, humid conditions. Higher probabilities for 25°C and 26°C versus 24°C or below stem from the limited potential for strong cooling in this environment, while probabilities above 27°C remain negligible given the typical diurnal range. Traders are weighing the latest model consensus and any updates to shower timing, which could shift the precise minimum by 1°C.
