Director General of the Pakistan Meteorological Department (PMD) Dr Muhammad Afzal said on Wednesday that a western weather system will enter the country from the afternoon of June 11, bringing pleasant weather and scattered rainfall to some regions, while Karachi is expected to remain humid.

Speaking to a local media outlet, Afzal said the system is likely to provide relief from the ongoing heatwave between June 11 and June 13. He said temperatures are expected to decline in several areas, including Gilgit-Baltistan, Kashmir, Gujranwala, Lahore, parts of Balochistan and Islamabad, where isolated rainfall may also occur.

For Karachi, Afzal said humid conditions are likely to persist, although sea breezes and winds are expected to provide some respite from the prevailing hot weather.

He said June is typically one of the hottest months of the year, and humidity levels generally rise during this period, making conditions more uncomfortable.

However, he noted that climate change is increasingly contributing to unusual and unpredictable weather patterns, resulting in sudden fluctuations in temperatures and rainfall.

Afzal said climate change has shifted average weather patterns toward more extreme conditions. Increased greenhouse gas emissions are warming the planet and disrupting atmospheric and ocean systems, leading to more frequent and intense heatwaves, heavy rainfall, floods, droughts and storms.

Responding to a query, he advised citizens to take preventive measures against heat-related illnesses, including staying hydrated, avoiding unnecessary exposure to direct sunlight and limiting outdoor activities during peak heat hours, which he said are hotter today than on previous days.

According to the Meteorological Department, there is currently no chance of rainfall in Karachi this month, and the dry spell and humid conditions are expected to continue.
