LAHORE:
There are growing concerns about an unusual rise in temperatures and potential heatwaves during the summer season in Punjab this year. According to reports from the Pakistan Meteorological Department (PMD) and international organizations, most parts of the province may experience intense heat from late April to June.
According to the PMD’s seasonal outlook, temperatures are expected to remain above normal from March to May 2026. The report indicates that in some areas, particularly South Punjab, temperatures may rise 4 to 6 degrees Celsius above average. On certain days, the increase could be even higher, creating heatwave conditions.
Data suggests that temperatures in April may be 1 to 2 degrees above normal, rising to 2 to 3 degrees above normal in May. In June, due to extreme heat, temperatures in some areas may reach 45 to 46 degrees Celsius.
In major urban areas, including Lahore, the intensity of heat is expected to feel even higher. Environmental expert Dr Zulfiqar Ali explains that due to concrete structures, traffic, and air pollution, an “urban heat island effect” develops in cities, causing temperatures to be higher than in rural areas. In Lahore, temperatures during May may reach 42 to 45 degrees Celsius.

According to the Meteorological Department’s heatwave alert system, temperatures of 42 degrees Celsius or higher are classified as a heatwave. If such high temperatures persist for several consecutive days, the situation can become more severe.
Director of the Meteorological Department in Lahore, Aleemul Hasan, stated that temperatures may reach up to 38 degrees Celsius by the end of April. He also noted that historically, Lahore has recorded temperatures as high as 46 degrees Celsius in April. He added that the likelihood of heatwaves will increase in May and June.
Director General of the Meteorological Department, Sahibzada Khan, also warned that temperatures in June and July could exceed 44 degrees Celsius, further intensifying the heat.
According to Dr Zulfiqar Ali, major causes of rising temperatures include climate change, reduced rainfall, high-pressure systems in the atmosphere, deforestation, and a lack of greenery in urban areas.
“Both the intensity and duration of heatwaves are increasing in Punjab. Hot and dry winds may intensify in South Punjab, and extreme heat could negatively impact the agricultural sector, particularly crop yields,” noted Dr Ali.
The Meteorological Department and related authorities have advised taking precautionary measures to cope with potential heatwaves. Citizens are urged to avoid unnecessary outdoor activities during peak heat hours, drink plenty of water, wear light clothing, and keep their heads covered.
Meanwhile, the Environmental Protection Department has recommended promoting tree plantation in cities, strengthening the heatwave alert system, ensuring hospitals are prepared to handle heatstroke cases, and maintaining water supply.
Experts have warned that if timely measures are not taken, heatwaves in Punjab may become more severe in the coming years, affecting human health, water availability, and energy demand.
