Recent forecasts from the Pakistan Meteorological Department and international models converge on a daily maximum near 32°C for Karachi on August 15, driven by persistent monsoon moisture, moderate cloud cover, and the moderating influence of the Arabian Sea breeze that typically caps afternoon highs in the low 30s during late August. Current observations show surface temperatures in the 27–30°C range under partly cloudy skies, with humidity above 70% limiting further warming. Historical climatology places the August average high around 31–32°C, and no major heat-wave or clear-sky developments have emerged to shift the distribution. The market’s heavy weighting on 32°C (51.5%) and 33°C (24.5%) reflects this narrow forecast spread, while lower probabilities for 31°C or 34°C capture residual uncertainty in afternoon convection and model timing of any showers. Updated guidance expected later today from regional models will likely refine the final resolution band.
