Recent Pakistan Meteorological Department guidance and ensemble model consensus indicate Karachi highs on June 12 will likely settle in the mid-to-upper 30s Celsius amid persistent pre-monsoon dry heat and variable sea-breeze influence. This positions 37°C as the modal outcome in trader pricing while adjacent brackets capture the remaining spread. Key variables include steering winds that could either enhance or suppress coastal moderation, the precise timing of any monsoon moisture incursion, and diurnal heating rates under high humidity. Updated short-range forecasts expected within 48 hours will refine these thresholds and may shift implied probabilities if afternoon maxima trend above or below current guidance.
