**Recent forecasts from multiple meteorological sources, including the Pakistan Meteorological Department (PMD) and international models, indicate overnight lows in Karachi on September 23 will likely settle near 27–28°C under clear to mostly clear skies with persistent westerly winds.** This aligns with the market’s leading outcome of 28°C (54.5% implied probability), reflecting trader consensus around the expected minimum. Karachi’s coastal position on the Arabian Sea typically moderates temperatures via sea breezes, though recent circulation changes over the sea weakened these breezes and drove a late-September heat spike (record 40.7°C maximum on September 21). Relief is now anticipated as winds shift, supporting the projected drop to seasonal norms. Historical September averages show typical overnight lows of 25–26°C, with the current forecast slightly above that due to lingering warmth and high humidity (often 70–85% at night). Options for 22°C or below (21.5%) or 26°C (21%) carry lower weight because models show limited cooling potential overnight, while higher thresholds like 32°C+ (19.5%) appear inconsistent with the expected diurnal range. Key upcoming factors include the next PMD update and any shifts in Arabian Sea pressure patterns that could alter wind strength or introduce minor cloud cover.

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.
