Recent official forecasts for Singapore on September 16 project nighttime minima near 26–27°C under prevailing southwest monsoon conditions, with limited diurnal cooling due to high humidity and cloud cover. Market-implied odds split evenly between 22°C or below and 32°C or higher reflect trader focus on forecast uncertainty from variable convective showers, wind shifts, and sea-breeze effects that can alter the exact low by 1–2°C. Equatorial location keeps the typical range narrow, with historical September minima averaging 25°C; resolution hinges on official observations from Changi or equivalent stations. Updated model runs and any late monsoon adjustments will likely drive near-term shifts in these closely matched probabilities.

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 16 Sep '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 for the observation date is unavailable by 11:59 PM ET on the day following the observation date, the Weather Underground Daily Observations table will be used as the resolution source.
In the event that there is no data for the observation date by 11:59 PM ET on the day following the observation date, this market will resolve to the lowest bracket.
To toggle between Fahrenheit and Celsius, click the "Switch to Metric Units" button until the relevant table displays °C.
This market will resolve once the first data point for the following date has been published on the resolution source, or by 11:59 PM ET on the day following the observation date, whichever comes first.
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 official forecasts for Singapore on September 16 project nighttime minima near 26–27°C under prevailing southwest monsoon conditions, with limited diurnal cooling due to high humidity and cloud cover.
