Latest forecasts from the Pakistan Meteorological Department and international models indicate overnight lows in Karachi on August 27 will likely settle near 26–27°C amid persistent southwest monsoon winds, high humidity near 80–85%, and partly to mostly cloudy skies that limit radiational cooling. These conditions, typical for late August in the coastal region, suppress temperature drops below seasonal norms of 26–27°C while preventing spikes above 28°C. Model consensus shows tight clustering around these values, with minor variations in cloud cover or wind speed determining whether the minimum registers at 25°C or 28°C. Traders assign near-equal weight to 25–28°C outcomes because new observational data from the evening of August 26 could still shift the final recorded low by 1–2°C before resolution.
