Forecast models from agencies like MET Malaysia and international sources indicate Kuala Lumpur's minimum temperature on September 20 will likely fall between 24–26°C under typical tropical conditions, with partly cloudy skies, scattered thunderstorms, and moderate humidity limiting nocturnal radiative cooling. Trader sentiment remains nearly balanced between 30°C-or-higher and 20°C-or-below outcomes because small shifts in cloud cover, rainfall timing, or wind patterns can alter the overnight low by 1–2°C, while historical September baselines hover near 25°C with low interannual variability. Upcoming model runs and surface observations through the weekend will clarify whether any transient haze or convective activity pushes readings outside the central range.

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=wmkk
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.
