Latest numerical weather prediction models from the Pakistan Meteorological Department and international centers point to a highest temperature of 31–32°C in Karachi on August 21, driven by persistent monsoon cloud cover and elevated humidity that suppress daytime heating below recent peaks near 34°C. These conditions align with typical late-August patterns, where Arabian Sea moisture and weak steering winds maintain overcast skies, limiting solar insolation and keeping maxima close to the 31.7°C monthly climatological average. Recent observations through mid-August confirm this moderation, with actual highs around 33°C yielding to increased cloudiness. Traders assign the highest implied probabilities to these outcomes because forecast ensembles show limited day-to-day variability and no strong signals for intensification or clearing that would push readings to 33°C or above. Final model updates and official briefings over the next 48 hours remain the key variables that could shift consensus.
