**Traders see the highest temperature in Karachi on July 9 centering on 34–35°C because short-range forecast models show only modest day-to-day variability around the seasonal mean.** July climatology places average daily maxima near 32–33°C, yet values routinely range 32–37°C depending on Arabian Sea breeze strength, low-level moisture advection, and cloud cover tied to the advancing monsoon. Current guidance indicates above-normal temperatures for Sindh through the month, with limited rainfall expected to suppress daytime cooling. The near-even split between the two leading outcomes reflects typical ensemble spread in maximum-temperature forecasts at this lead time, where small differences in wind direction or timing of any sea-breeze onset can shift the daily peak by 1°C. Updated model runs and Pakistan Meteorological Department guidance over the next 48 hours will likely tighten or shift these probabilities.
