**Forecast models from multiple sources, including the Pakistan Meteorological Department influences and international ensembles like GFS, converge on a minimum temperature near 26–27°C for Karachi on August 29, 2026, driven by persistent southwesterly monsoon flow, high humidity (70–85%), and extensive low-to-mid cloud cover that limits nocturnal radiative cooling.** Strong winds of 15–20 mph from the west or southwest, typical of the Arabian Sea sea-breeze regime in late summer, further mix the boundary layer and prevent sharp drops, keeping overnight lows well above the 23°C or lower thresholds. Recent developments show the southwest monsoon in its final phase with below-normal rainfall expected in Sindh, reducing the chance of heavy cloudbursts or enhanced cooling from evaporation; instead, mostly cloudy to overcast skies with only isolated light drizzle are projected, moderating but not suppressing temperatures. Historical climatology places typical late-August minima around 26–27°C, and current model runs show little deviation from this baseline through the weekend. With resolution hinging on the precise overnight low reported by official stations, the closely bunched market probabilities around 24–28°C reflect trader recognition of this narrow uncertainty band, where small shifts in cloud timing or wind strength could tip the outcome within the 25–27°C cluster while making extremes (below 23°C or 29°C+) far less probable under the prevailing synoptic pattern.
