The Pakistan Meteorological Department (PMD) has predicted an intensification of the ongoing cold wave in Karachi starting from Saturday, January 4.
The cold conditions, which have already brought significant temperature drops in recent weeks, are expected to worsen as a fresh wave of westerly winds sweeps through the region.
The PMD noted that while Karachi might experience a slight respite from the chill today and tomorrow (Friday), incoming westerly winds could bring rain to Balochistan. These rains are likely to be followed by colder winds making their way to Karachi, further lowering temperatures in the city.
Currently, the metropolis is experiencing cold and dry weather conditions. The PMD reported a minimum temperature of 13.5 degrees Celsius on Thursday, with humidity levels recorded at 58% and wind speeds reaching six kilometers per hour from the north.
The forecast comes on the heels of a chilly December, during which the mercury dipped to single digits multiple times, with lows of 9.1°C and 9.5°C recorded in the city. Karachi residents are bracing for similar or colder conditions as the new year begins.
Adding to the discomfort, Karachi’s air quality remains a major concern. The city recorded its highest pollution levels on December 31, 2024, according to Swiss air quality monitoring platform IQAir. Karachi’s Air Quality Index (AQI) stood at 237, a level classified as “very unhealthy” by international standards.
The concentration of PM2.5 pollutants — tiny particulate matter capable of entering the bloodstream — was measured at 162 µg/m³, exceeding World Health Organization (WHO) guidelines by 32.4 times. Such pollution levels pose serious health risks, particularly to vulnerable populations, and exacerbate the challenges posed by the cold wave.
Residents are advised to take necessary precautions to mitigate the effects of both the cold and poor air quality. Health experts recommend wearing protective masks, using air purifiers indoors, and limiting outdoor activities, especially for children, the old-age, and those with pre-existing respiratory conditions.
