Recent GFS and regional model guidance points to a daytime maximum of 31–32°C in Karachi on October 5 under partly cloudy skies, southwest sea breezes, and light moisture that limits insolation and enhances evaporative cooling. These conditions align with the post-monsoon transition, when marine air advection typically caps peaks below late-September levels. Market pricing slightly favors 33°C because recent observations have run 1–2°C warmer than some guidance and because coastal humidity can introduce model bias in the final 48 hours. Updated PMD and ECMWF runs, plus any overnight convective development, remain the key variables that could shift the outcome between the closely bunched 31–33°C range.
