Current Pakistan Meteorological Department outlooks and regional model runs point to mid-May maxima in Karachi settling in the 34–36 °C range, producing the tight clustering of market-implied odds between 34 °C, 35 °C, and 36 °C or higher. The decisive variables are the timing and strength of the afternoon sea breeze from the Arabian Sea, which can shave 1–2 °C off peak readings when it arrives before 1400 local time, versus drier north-westerly continental flow that allows greater surface heating. Low-level humidity near 60–70 % and any scattered afternoon cloud cover further modulate the outcome, while historical May averages of 33–35 °C provide the climatological baseline. Updated PMD guidance and final 48-hour forecasts issued in the next two days will resolve the narrow remaining uncertainty before the 18 May observation window closes.
