Recent forecasts for Karachi on August 21 point to a daily high near 31–33°C, reflecting the moderating effects of the South Asian monsoon, including increased cloud cover, high humidity, and sea breezes from the Arabian Sea. These conditions typically cap extremes during peak monsoon, aligning with climatological averages of 31–32°C for the period. Slight differences among numerical weather prediction models in the timing or coverage of showers and steering winds create the tight clustering around 31–32°C, while any clearer skies or delayed moisture could briefly push readings toward 33°C. Official updates from agencies like the Pakistan Meteorological Department will refine the outlook ahead of resolution.
