Recent forecast models from agencies like the Pakistan Meteorological Department and global ensembles show a minimum temperature near 28°C for Karachi on September 27, supported by persistent southwesterly sea breezes, partly cloudy skies, and high humidity levels around 70-80% that limit nocturnal radiative cooling. These conditions, following the end of monsoon influence with mainly dry air masses, favor the market's leading 28°C outcome while keeping cooler thresholds like 22°C or below viable if unexpected clear skies or reduced wind allow greater heat loss. Warmer possibilities above 30°C hinge on stronger daytime heating carrying over or model underestimation of urban heat effects. Updated PMD guidance and next model runs will refine the narrow spread between these scenarios.
