Recent residual monsoon effects and the transition to clearer, drier conditions are the main drivers behind the near-even market split on Karachi’s minimum temperature for September 20. Official forecasts and ensemble models currently indicate overnight lows of 26–28 °C under mostly clear skies and light southwesterly winds, consistent with post-monsoon stabilization and Arabian Sea moderation via sea breezes. Slight differences in nocturnal cloud cover, humidity retention, and wind speed among model runs create genuine uncertainty around the precise minimum, keeping broad low-end and high-end bins near 50 % each while narrower bins trade lower. Historical September minima average near 25 °C, providing context for the current range. Updated model runs and Pakistan Meteorological Department observations over the next 48 hours will likely narrow trader consensus.

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.
