**Coastal moderation from the Arabian Sea combined with active monsoon moisture is anchoring trader expectations for Karachi's August 15 maximum near 31–33 °C.** Long-term climatology and recent model guidance place typical mid-August highs around 88–90 °F (31–32 °C), with daily ranges rarely exceeding 93 °F (34 °C) or falling below 85 °F (29 °C) absent strong subsidence. Current Pakistan Meteorological Department outlooks and extended forecasts indicate continued monsoon influence through mid-month, featuring patchy rain or thunderstorms that enhance cloud cover, boost humidity, and limit daytime heating via evaporative cooling and reduced insolation. The market's heaviest weighting on 32 °C (50.5 %) reflects this consensus, while the secondary clusters at 31 °C and 33 °C capture uncertainty around exact rainfall timing and intensity on the 14–15th. Recent observations show above-normal warmth in interior Sindh but tempered coastal values, with no signals of an extreme heat spell that would shift probabilities toward 34 °C or higher. Updated numerical guidance and official briefings over the next 48 hours will be the key near-term catalysts for any repricing.
