Recent model runs and Pakistan Meteorological Department guidance indicate peak temperatures in Karachi on September 13 will likely reach 36–38°C under mostly clear skies and moderate westerly winds ahead of a westward-moving low-pressure system from the Bay of Bengal. This pre-rain heat buildup aligns with historical early-September averages near 32–34°C but elevated by recent dry conditions and limited cloud cover. Key variables differentiating market-implied outcomes include precise timing of any early moisture advection, wind gust strength, and urban heat-island effects at official recording stations, with traders weighting ensemble spreads that show modest upward bias in maximum readings before thunderstorms arrive on September 14–15. Updated official forecasts and station data releases remain the next market catalysts.

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=opkc
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.
