Karachi’s mid-June pre-monsoon setting keeps maximum temperatures tightly clustered near the long-term 34–36 °C climatological range, with the 35 °C and 34 °C brackets dominating trader consensus because local sea-breeze timing and strength remain the decisive variables. A timely, strong south-westerly flow off the Arabian Sea advects cooler, moister marine air that caps afternoon heating near or below 35 °C; any delay or weakening of this breeze allows greater insolation and warmer continental air to push the peak toward 36 °C or higher. Recent observations show highs fluctuating between 36–40 °C amid generally clear skies and moderate humidity, while model guidance and Pakistan Meteorological Department outlooks for 15 June indicate little change in the steering pattern, preserving the narrow probability spread between the two leading outcomes.
