Monsoon-driven cloud cover, high humidity, and frequent rain-wind activity across southern Pakistan continue to suppress maximum temperatures in Karachi, keeping daily highs near the seasonal August average of 31–33°C. Official Pakistan Meteorological Department guidance and model consensus through August 20 emphasize partly cloudy to overcast conditions that reduce incoming solar radiation and enhance evaporative cooling, with limited intensification expected before the next forecast update. These factors underpin the market’s heaviest weighting on 32°C, followed by adjacent 31–33°C outcomes, while the modest probabilities attached to 34°C or higher reflect only slim chances of clearer skies or reduced moisture allowing brief warming. Traders are monitoring the next PMD and global model runs for any shift in steering patterns or rainfall timing that could alter peak readings before resolution.
