**Trader consensus clusters tightly around 26–27°C as the implied lowest temperature for Karachi on August 28, reflecting stable late-monsoon conditions and limited day-to-day variability in overnight minima.** Recent Pakistan Meteorological Department observations show nighttime lows consistently between 26–27°C through late August, aligning with climatological averages near 81°F (27.2°C) and the narrow historical range rarely dipping below 79°F. Multiple forecast models indicate mostly cloudy skies, light or no precipitation, and steady west-to-southwest winds of 6–7 m/s that sustain high humidity (80–90%) and moderate radiational cooling along the Arabian Sea coast. These factors limit differentiation among the leading outcomes, as small shifts in cloud cover or wind speed overnight can nudge the minimum by 1°C. With resolution hinging on the official daily low reported by local stations, traders appear to weigh the narrow spread of current model guidance and the absence of stronger monsoon surges or clear-sky radiative cooling events expected before August 28.
