Traders assign the highest probability (45.5%) to a 33°C maximum in Karachi on August 6 because recent numerical weather prediction runs and climatological baselines place the most likely official reading in the narrow 32–34°C range. Persistent monsoon moisture, with the Pakistan Meteorological Department noting continued activity into early August, supports increased cloud cover and scattered showers that moderate daytime heating while still allowing afternoon peaks near seasonal norms of 31–32°C. Model consensus from global ensembles shows limited variability in steering patterns and sea-surface temperatures in the Arabian Sea, keeping extreme outliers below 10% implied probability. With the market resolving on the next day’s official observation, any late shift in convective activity or clearer skies could nudge the recorded high within that tight window.
