**Trader consensus centers on 26–28°C as the most probable range for Karachi’s lowest temperature on August 22, 2026, with 27°C holding the highest implied probability at 52%.** This positioning aligns with official forecasts and climatological data showing typical overnight lows of 26–27°C (79–81°F) during late August. Karachi’s coastal location on the Arabian Sea moderates extremes, while the active but below-normal monsoon maintains high humidity and frequent cloud cover that limits radiative cooling overnight. Current model guidance from sources such as AccuWeather and the Pakistan Meteorological Department indicates no significant cold-air intrusion or clear-sky radiative event that would push minima notably lower. Historical averages place August nighttime temperatures around 26–27°C, with rare dips below 26°C absent unusual synoptic shifts. Recent developments reinforce stability: persistent hot-humid conditions across Sindh, limited rainfall in the south, and steady steering patterns have kept temperature forecasts unchanged in the past week. Upcoming model runs and official updates from the PMD will be the next potential catalysts if they revise cloud cover or moisture expectations. The market’s tight clustering around 26–28°C therefore reflects the narrow uncertainty band typical of mature seasonal forecasts for this location and time of year.
