Current forecasts for Kuala Lumpur on September 18 show overnight lows clustered between 24–27°C amid widespread thunderstorms, high humidity near 80–90%, and persistent cloud cover that limits radiative cooling. These conditions, typical during the southwest monsoon transition, prevent the sharper nocturnal drops seen in drier periods, keeping daily minima near historical September averages of 23–25°C. Trader consensus between 25°C and 26°C reflects model agreement on light winds and dew points near 25°C, with lower probabilities for 20°C or below tied to the low likelihood of clear skies or anomalous dry air intrusions. Official station readings from the Malaysian Meteorological Department will resolve the market once the full diurnal cycle is recorded.

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.
