Recent forecasts from multiple models show Karachi under stable high-pressure conditions with sunny skies and light westerly winds through September 22, supporting overnight lows near 26–27 °C. This places the expected minimum squarely between the market’s closely matched leading outcomes (23 °C or below at 50.0 % and 29 °C at 49.5 %), reflecting typical uncertainty ranges in minimum-temperature resolution. Historical September climatology for the city centers on 26–28 °C lows, with no incoming monsoon surge or cold-air advection to push readings notably lower. Traders are therefore pricing the narrow band of possible model spread and local microclimate effects rather than any dramatic shift in large-scale patterns.

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