**Forecast consensus from multiple models points to an overnight low of 25–27°C for Karachi on August 30, 2026, aligning closely with the market’s leading outcomes (26°C at 39.5%, 27°C at 29.5%, 28°C at 26.0%, and 25°C at 25.5%).** Karachi’s coastal position on the Arabian Sea sustains elevated humidity and moderate sea breezes that limit nocturnal cooling, while persistent westerly to southwesterly winds and extensive cloud cover further moderate temperature drops. Current late-August conditions reflect typical post-monsoon stabilization, with recent observed lows ranging 26–28°C and no significant synoptic shift (such as stronger monsoon inflow or clear-sky radiative cooling) expected to push values outside this band. Model runs show high agreement on a minimum near 26°C, with minor spread reflecting uncertainty in exact cloud timing and wind strength overnight. Traders appear to price the highest probabilities around the central forecast values, with lower odds assigned to extremes below 23°C or above 29°C due to the stabilizing marine influence and historical climatology for the period. New observational data or updated model runs on the morning of August 30 could refine these implied probabilities.
