Current forecast consensus from regional models indicates a highest temperature in Karachi on September 18 most likely in the 33–34°C range, with trader probabilities reflecting narrow spreads around these outcomes amid typical post-monsoon conditions. Southwesterly winds, high humidity near 60–70%, and partly cloudy skies are expected to limit extreme heating while urban heat effects and measurement timing at official stations introduce modest variability. Historical September averages near 32–33°C provide climatological context, yet short-range model updates over the next 48 hours remain the key variable that could shift implied odds if afternoon maxima edge higher or are suppressed by increased cloud cover.

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.
