Current forecasts for Karachi on September 20 point to a maximum near 35–38 °C under mostly clear skies and light westerly winds of 8–15 km/h, keeping trader focus tightly split between 36 °C and 37 °C. Daytime solar heating under low cloud cover and modest humidity (50–60 % afternoon levels) drives efficient surface warming, while onshore flow from the Arabian Sea moderates extremes. Minor model differences in peak wind speed or residual moisture explain the narrow spread; official Pakistan Meteorological Department or airport station readings will resolve the exact value. Historical September highs average 32–34 °C, so any exceedance of 37 °C would require stronger subsidence or reduced sea-breeze cooling than currently indicated.

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.
