Strong El Niño conditions, expected to intensify through September 2026, represent the main driver behind current trader positioning, as they typically suppress rainfall and enhance temperatures across Peninsular Malaysia. Historical September minimums in Kuala Lumpur average near 24°C, with most nights ranging 22–25°C, yet the drier, hazier pattern can limit nocturnal cooling and support readings at or above 25–26°C. Local factors including urban heat retention, variable overnight cloud cover, and any late-day convection introduce genuine uncertainty, keeping 25°C, 26°C, and 29°C-or-higher outcomes nearly tied in implied probability while lower thresholds receive less support. Updated Malaysian Meteorological Department guidance and short-range model runs ahead of September 7 will likely refine the outlook.

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.
