Recent forecasts from multiple models, including GFS-based outputs, indicate minimum temperatures in Karachi near 26–27°C on September 4, consistent with seasonal norms and current partly cloudy, humid conditions influenced by Arabian Sea moisture. The closely matched market-implied odds on the 21°C-or-below and 31°C-or-higher extremes reflect genuine uncertainty in short-term variables such as nocturnal radiative cooling under variable cloud cover, wind speed from the west or southwest, and localized humidity levels that can suppress or enhance temperature drops. Persistent drizzle or thicker cloud decks, as seen in recent overnight reports, limit cooling and favor higher minima, while clearer breaks could allow greater nocturnal heat loss. Upcoming model updates from agencies like the Pakistan Meteorological Department will likely refine these thresholds before resolution.
