**Forecast models from sources including GFS and agency outputs indicate peak temperatures of 31–33°C in Karachi on October 4 under predominantly clear skies, moderate westerly winds of 15–25 km/h, and low precipitation chances below 10%.** These conditions support efficient daytime heating after overnight lows near 26–27°C, consistent with early-October climatology where dry post-monsoon air masses prevail and humidity remains elevated but does not suppress maxima. Recent model runs show tight consensus around this range, with limited spread from steering patterns or cloud cover, positioning 33°C as the modal outcome in trader pricing while 32°C and 34°C capture residual uncertainty in exact peak timing or microscale variations. Official monitoring from the Pakistan Meteorological Department and international guidance will provide the final verified high for market resolution.
