The humidity patterns in Karachi are influenced by several climatic factors, including the seasonal monsoon rains which bring both relief from high temperatures and increased humidity. The southwest monsoon, which typically begins in June and peaks in July and August, brings heavy rainfall to the region, further raising the moisture content in the air. Conversely, the winter months from December to February see a decrease in humidity as the prevailing winds shift to a more northerly direction and the weather becomes drier. Despite these seasonal variations, Karachi’s overall humidity remains relatively high throughout the year, with average relative humidity levels ranging from 60% to 80%, which is typical for coastal cities. Understanding these patterns is crucial for both local inhabitants and visitors to prepare for the climatic conditions and to take appropriate measures to manage comfort and health in Karachi’s varied seasons.
