Recent forecasts from models including GFS indicate Karachi’s overnight low on September 19 will hover near 26–27°C under mostly clear to partly cloudy skies and light southwesterly winds following the monsoon’s final light rain on September 17. High humidity near 75–85% and the city’s coastal location will moderate radiative cooling, keeping minimum temperatures close to the seasonal average of roughly 27°C while limiting the chance of sharper drops below 25°C. Trader sentiment remains split between the 27°C and 22°C-or-below bins because subtle differences in cloud cover, wind speed, or dew-point depression in the final model runs could shift the observed minimum across those thresholds. Updated Pakistan Meteorological Department guidance and late-hour observational data will likely determine resolution.
