Latest Pakistan Meteorological Department guidance and GFS model consensus indicate a daytime maximum near 35°C in Karachi on October 15 under partly cloudy skies with moderate southwest winds and typical post-monsoon humidity. This aligns with mid-October climatology for coastal Sindh, where sea breezes and haze often moderate extremes around the seasonal average high of 33–36°C. The 92.5% market-implied probability for exactly 35°C reflects traders’ assessment of stable steering patterns and limited model spread, with minimal recent shifts in observational data. Clearer skies or stronger subsidence could push readings to 36–37°C, while increased cloud cover or light drizzle would favor a lower outcome, though both remain low-probability scenarios given current conditions.
