Traders are pricing in substantial forecast uncertainty for Kuala Lumpur's minimum temperature on September 7, with no single outcome exceeding 35% implied probability. Primary drivers include the strength of nocturnal radiative cooling under variable cloud cover and humidity levels typical of the inter-monsoon period, plus the urban heat island effect that often keeps city-center readings several degrees above rural baselines. Ensemble model spreads from agencies like the Malaysian Meteorological Department highlight sensitivity to any passing showers or increased low-level moisture, which would suppress cooling and favor outcomes near 25–29°C, while clearer conditions could allow dips toward 22–24°C. Historical September minima average around 24°C, providing context for the tight clustering between 24°C and 29°C or higher. Updated model runs and satellite observations of regional convection over the next 48 hours will likely refine these probabilities before resolution.

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.
