Traders assign the highest implied probability (29.5%) to a minimum of 20°C or below on September 8 in Kuala Lumpur, with the next cluster of outcomes (24–26°C) each near 26.5%, reflecting genuine forecast uncertainty for the day’s overnight low. Official Malaysian Meteorological Department guidance and multiple model runs indicate typical September inter-monsoon conditions with scattered thunderstorms, haze, and highs near 33–35°C, supporting overnight lows around 24–25°C as cloud cover and high humidity (often above 80%) limit radiative cooling. Recent regional smoke and variable precipitation may enhance localized cooling or suppress it depending on timing and intensity, while urban effects and model spread in boundary-layer moisture create the observed market dispersion. New official observations and updated model guidance expected overnight will likely resolve the 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.
