**Trader consensus centers on 26–27°C as the most probable minimum temperature for Karachi on September 8, reflecting stable post-monsoon conditions and consistent model guidance.** Official forecasts from regional meteorological services project overnight lows near 26°C, driven by southwest monsoon flow, high humidity near 80–90%, and light to moderate winds that limit radiational cooling over the coastal plain. Historical September climatology shows typical minimums of 25–27°C, with current observations and short-range models showing no significant departures or incoming weather systems that would produce greater cooling. The narrow spread in implied probabilities underscores limited forecast uncertainty for this timeframe, though any late-day convective activity or wind shifts could nudge the final recorded low.
