Recent forecasts for Karachi on September 14, 2026, point to overnight minimum temperatures near 27–28°C under partly cloudy skies with scattered thunderstorms possible from a westward-moving low-pressure system originating in the Bay of Bengal. This synoptic pattern, developing over the northwestern Bay and adjacent coastal areas, is expected to increase cloud cover and humidity while introducing light winds from the west-southwest, moderating radiative cooling and limiting the potential for either sharp drops below 24°C or sustained warmth keeping the low above 30°C. Model consensus from sources like the GFS aligns with historical September climatology for the coastal Sindh region, where typical minima hover around 26–28°C amid the post-monsoon transition. The market's emphasis on 28°C as the leading outcome reflects this baseline expectation, while probabilities attached to cooler or warmer extremes capture uncertainty in the timing and intensity of rainfall that could alter the overnight temperature trajectory before official Pakistan Meteorological Department observations finalize the daily minimum.
