Trader consensus around 25–27°C for Karachi’s October 15 low reflects model consensus on typical post-monsoon coastal conditions, where the Arabian Sea moderates overnight radiative cooling under partly cloudy skies and light westerly winds. Recent hot days with highs near 35–38°C have given way to gradual evening declines, but persistent humidity near 70–90% and minimal cloud cover limit further drops below the mid-20s. Differences among 25°C, 26°C, and 27°C outcomes hinge on subtle variations in wind speed, dew-point depression, and the precise timing of the minimum, as local observations and ensemble forecasts show small spreads. Official Pakistan Meteorological Department guidance and global models indicate dry, stable air masses with no major synoptic shifts expected before resolution.
