Recent forecast models from the Pakistan Meteorological Department and international sources point to minimum temperatures in Karachi on October 16 likely falling in the 23–25°C range under mostly clear skies and light northeasterly to westerly winds, yet the market's leading 21°C-or-below outcome at 49.5% implied probability reflects trader focus on potential for enhanced nocturnal radiative cooling amid the recent weakening of the sea breeze and persistent hot, dry conditions. October climatology shows average lows near 23°C, with recent observations including a 25.8°C minimum early in the month and elevated daytime maxima exceeding 38°C on October 13. Key variables include wind speed reductions that could lower the minimum further and any late adjustments in model consensus ahead of resolution.
