Recent forecasts from multiple models indicate overnight lows in Karachi of 26–27°C on August 28, consistent with late-August climatology and recent observed minima near 26.6°C. Westerly winds at 14–17 mph, persistent high humidity above 70%, and variable cloud cover limit nocturnal radiative cooling, keeping the daily minimum close to these values. The tightly clustered market probabilities around 25–27°C reflect genuine uncertainty in precise model consensus and local urban heat effects, with traders weighing subtle differences in forecast timing and boundary-layer moisture against historical norms of roughly 27°C. Updated runs from agencies like the Pakistan Meteorological Department will provide the next key data points ahead of resolution.
