Recent forecasts from multiple models indicate a typical late-monsoon minimum near 25–27°C for Karachi on September 1, driven by persistent southwesterly winds off the Arabian Sea, high humidity near 70–90%, and partly cloudy skies that limit nocturnal radiative cooling. This places the outcome near historical late-August/early-September averages of 26–27°C, with limited day-to-day variability expected absent a stronger monsoon surge or clearer skies. The closely matched market probabilities across bins reflect genuine forecast uncertainty in the precise overnight low, as ensemble spreads and model differences remain modest but non-negligible this close to the observation window. Traders are weighting the balance between typical marine moderation and any potential for slightly drier or windier conditions that could nudge the minimum a degree or two in either direction.
