**Current forecast models from sources including the Pakistan Meteorological Department (PMD) and international agencies point to overnight lows near 26°C in Karachi on October 1, aligning with the market's leading 44% implied probability for that outcome.** Persistent above-normal temperatures across Sindh, driven by seasonal patterns and limited cooling from westerly influences, have kept recent minimums in the 27–29°C range. Model consensus shows clear skies and light winds limiting radiative cooling, with historical October lows averaging around 23°C providing context for the slight elevation. Updated PMD guidance and ensemble runs through late September reinforce this trajectory ahead of the October 1 resolution window, though minor forecast adjustments remain possible with final observational data.
