Recent official forecasts for Karachi on October 15, 2026, project a minimum temperature of 26–27°C, aligning with the market's strong 72.5% implied probability for 27°C. This reflects consensus across models showing limited nocturnal cooling from the Arabian Sea's moderating influence, combined with high humidity, light variable winds, and post-monsoon subsidence that maintains warm overnight conditions. Historical October averages place typical lows near 24–26°C, but current data indicate slightly elevated minima due to persistent warmth. Traders appear to weigh the low likelihood of sharper drops below 25°C absent unexpected synoptic shifts, with resolution hinging on verified observations from local meteorological stations.
