**Trader consensus clusters tightly around 35–36°C as the most likely peak for Karachi on October 12, reflecting uncertainty in how strongly the Arabian Sea breeze will moderate daytime heating.** Pakistan Meteorological Department guidance highlights a high-pressure pattern that could weaken the usual southwesterly sea breeze, allowing clearer skies and reduced marine cooling to push maxima into the mid-30s, consistent with recent model runs showing 34–37°C under light westerly flow. Current partly cloudy conditions and moderate humidity (around 70–80%) are expected to give way to sunnier weather, though lingering onshore winds or minor cloud cover could cap the high nearer 34°C. Historical October baselines for Karachi hover near 32–34°C, so the slight elevation hinges on whether synoptic changes fully suppress the cooling sea breeze over the next 48 hours. Fresh PMD updates and morning model guidance on October 11–12 will likely refine these narrow odds before resolution.
