Light drizzle and intermittent rain fell across several parts of Karachi on Monday as a seasonal monsoon system moved through the region [2].

These weather patterns are critical for the city's infrastructure, as moisture and strong sea winds can disrupt daily transit and urban drainage in the densely populated coastal hub.

The Pakistan Meteorological Department (PMD) said the weather was caused by a westerly wave associated with the seasonal monsoon. This system brought an influx of moisture and strong sea winds to the area [2].

According to the PMD, residents of Karachi can expect partly cloudy skies, warm and humid weather, and a chance of strong winds and light drizzle over the next three days [1]. The forecast was issued on June 25, 2026 [1].

While some reports mentioned heavier precipitation, the PMD forecast specifically highlighted light drizzle and intermittent rain [2]. The agency said that thunderstorms were possible under the influence of the westerly wave [2].

City officials typically monitor these shifts in wind and moisture to manage potential urban flooding. The current system is characterized by its intermittent nature rather than sustained heavy downpours [2].

“Residents of Karachi can expect partly cloudy skies, warm and humid weather”

The arrival of a westerly wave during the monsoon season indicates a shift in atmospheric pressure that typically brings relief from extreme heat but introduces humidity and wind. For Karachi, this means a period of unstable weather where light rain can occur suddenly, requiring the city to maintain readiness for minor urban flooding despite the lack of heavy storm warnings.
