Current numerical weather prediction models from sources including the Pakistan Meteorological Department and international ensembles indicate a minimum temperature near 26°C for Karachi on September 11, driven by typical late-summer conditions with light southwesterly flow, high humidity, and moderation from the Arabian Sea. Overnight radiative cooling under partly cloudy skies is expected to produce the daily low in the mid-20s Celsius during pre-dawn hours, consistent with climatological baselines of roughly 26–27°C for early September. No significant synoptic features such as stronger monsoon surges or upper-level troughs are forecast to alter this pattern before resolution. Trader emphasis on the 26°C outcome reflects this model consensus, while probabilities for warmer or cooler extremes capture residual uncertainty in exact minimum timing and local urban heat island effects.
