Trader consensus around 26°C as Karachi’s lowest temperature on October 12 reflects consistent forecasts from the Pakistan Meteorological Department and global models projecting an overnight low of 25–26°C. Clear skies, moderate westerly winds, and typical mid-October coastal humidity support radiative cooling to this level without significant cloud cover or moisture to moderate overnight drops. Historical October averages near 24–26°C further anchor expectations. A realistic challenge would require unexpected shifts such as stronger onshore flow, localized urban heat effects altering station readings, or final observational adjustments at primary sites differing from model consensus.
