Latest forecast models from the Pakistan Meteorological Department and global ensembles like GFS project a maximum temperature of 32–33°C in Karachi on September 30, driven by persistent southwest monsoon flow, moderate humidity around 60%, and mostly clear skies that limit daytime heating. This aligns with climatological norms for late September, when daily highs typically range 31–34°C before the post-monsoon transition. Recent cooling from the mid-September heat spike (peaking above 40°C) has stabilized conditions, with no significant tropical moisture or wind shifts expected to push readings higher. Traders appear to weight the tight model consensus and short time horizon heavily, as resolution depends on official station readings rather than broader regional trends.
