**Forecast models from sources like WeatherBug and the Met Office point to a peak of 38–39°C in Karachi on September 21 under mostly sunny skies, light northwest winds of 9–11 mph, and afternoon humidity dropping to 35–50%.** This setup favors strong solar heating after the monsoon’s retreat, with minimal cloud cover and a sea breeze that moderates but does not fully suppress daytime maxima. Recent observations show temperatures rising from 33–35°C on September 19 toward 36–38°C by September 20, consistent with climatological warming in late September. Traders assign the highest implied probabilities to 38–40°C because ensemble guidance clusters there, while lower odds on extremes reflect the low chance of significant model shifts or unexpected moisture before resolution.

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.
