Recent forecasts from Malaysia's Meteorological Department and supporting models highlight persistent haze combined with isolated thunderstorms on September 19, which limit solar insolation and moderate peak heating in Kuala Lumpur's tropical urban environment. These conditions, typical of the inter-monsoon period, support market-implied odds favoring a daily maximum near 31–32 °C rather than higher values that would require clearer skies and stronger insolation. The urban heat island effect, driven by built-up surfaces and low wind speeds, provides a modest upward bias, while high humidity and cloud cover introduce downward pressure. Historical September averages around 32–33 °C align with this outlook, though afternoon convective activity could shift the observed high by 1–2 °C depending on timing and intensity of any showers. Updated model runs and official briefings tomorrow morning will refine resolution criteria for this single-day temperature market.

The resolution source for this market will be information from NOAA, specifically the highest 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.
