Pakistan Meteorological Department guidance and supporting forecast models point to a daytime maximum of 36°C in Karachi today, driven by persistent sea-breeze circulation from the Arabian Sea that offsets typical late-spring heating. This coastal moderation keeps surface temperatures from climbing further despite elevated regional heat content ahead of the monsoon onset. Trader consensus has aligned tightly with these official projections, pricing the 36°C outcome near certainty while assigning negligible probability to 37°C or higher. An unexpected weakening of the sea breeze or a late surge in upper-level subsidence could allow brief exceedance of the threshold, but current model consensus shows little support for such shifts before sunset.
