In a significant weather development, Karachi recorded its hottest day of the current season as disrupted sea breezes caused a sharp rise in temperature across the city.
According to the Pakistan Meteorological Department (PMD), the temperature surged to around 39.5 degrees Celsius, marking an increase of nearly 3.7°C compared to the previous day. The sudden spike was attributed to weakened sea winds and rising atmospheric pressure.
Meteorologists explained that a low-pressure system near Oman interfered with the normal southwest sea breeze, which typically provides relief to the coastal city. As a result, sea winds remained partially or completely inactive during the day, leading to hotter and more humid conditions.
Despite the intense heat, officials clarified that the situation does not yet qualify as a formal heatwave. Humidity levels hovered around 35 per cent, preventing extreme heatwave conditions, though the weather remained uncomfortable for residents.
Experts noted that Karachi’s weather heavily depends on sea breezes, which usually moderate temperatures during the summer months. Any disruption in these winds can quickly lead to a noticeable rise in heat intensity.
Authorities have advised citizens to take precautionary measures, including staying hydrated and avoiding unnecessary exposure to direct sunlight during peak hours. Health experts also warn that even without a declared heatwave, such conditions can still pose risks, particularly for vulnerable groups.
The PMD has indicated that relief may be on the way, with temperatures expected to gradually decrease from Tuesday as normal sea breeze patterns resume.
The latest weather conditions highlight the city’s vulnerability to short-term climatic shifts, where even minor disruptions in sea winds can significantly impact daily life.
