Punjab is set to experience an unusually intense and prolonged heatwave this summer, with temperatures expected to remain above normal from April through June, according to the Pakistan Meteorological Department (PMD).
The warning signals a difficult summer ahead, particularly for urban populations and agricultural regions already under climate stress.
How Hot Will It Get?
The data from PMD outlines a clear upward trend in temperatures:
- April: 1–2°C above normal
- May: 2–3°C above normal
- Peak spike areas: 4–6°C above average
- June peak temperatures: 45–46°C in some regions
By definition, temperatures of 42°C or higher qualify as a heatwave, especially if they persist for several consecutive days.
👉 This means large parts of Punjab are likely to cross into heatwave territory multiple times during the season.
South Punjab to Face the Worst Impact
Data indicates that South Punjab will experience the most extreme conditions, with hotter and drier winds intensifying the heat.
Cities expected to be heavily affected include:
- Multan
- Bahawalpur
- Dera Ghazi Khan
These regions typically experience higher baseline temperatures, and climate trends are now amplifying that effect.
Urban Heat Effect Will Make Cities Feel Even Hotter
Major cities like Lahore may feel even hotter than recorded temperatures due to the urban heat island effect.
Factors contributing to this include:
- Concrete infrastructure
- Traffic emissions
- Reduced green spaces
- Air pollution
As a result, Lahore could see 42–45°C in May, with “feels like” temperatures even higher.
Why This Heatwave Is More Severe
Experts point to multiple structural causes behind rising heat intensity:
- Climate change increasing baseline temperatures
- Reduced rainfall limiting natural cooling
- High-pressure atmospheric systems trapping heat
- Deforestation and urban expansion reducing cooling capacity
Additionally, global weather patterns could further intensify heat and weaken monsoon relief later in the season.
Economic and Agricultural Risks
The heatwave is not just a weather event — it has real economic implications:
Agriculture
- Heat stress may reduce crop yields
- Irrigation demand will increase
- Risk to wheat and cotton cycles
Energy
- Higher electricity demand for cooling
- Increased load shedding risk
Health
- Rising cases of heatstroke and dehydration
- Higher risk for elderly and outdoor workers
Experts warn that prolonged heatwaves could disrupt both food security and energy stability.
Timeline: When the Heat Will Peak
The data suggests a clear timeline:
- Late April: Initial rise (around 38°C)
- May: Frequent heatwaves begin
- June: Extreme heat phase (45–46°C peaks)
The most dangerous period is expected between mid-May and late June, when temperatures remain consistently high.
What Authorities Are Advising
Officials have issued precautionary guidelines to reduce risks:
- Avoid outdoor activity during peak hours
- Drink plenty of water
- Wear light, loose clothing
- Cover your head when outside
Authorities are also working on:
- Heatwave alert systems
- Hospital preparedness
- Water supply management
Bigger Picture: A New Climate Reality
The data shows a clear pattern:
Heatwaves in Punjab are becoming longer, hotter, and more frequent
This is no longer a seasonal anomaly — it is a structural climate shift affecting:
- Public health
- Agriculture
- Urban living
- Economic stability
Conclusion: Punjab’s Tough Summer Ahead
Punjab is heading into one of its most intense summers in recent years, with temperatures expected to push toward 46°C and remain consistently above normal.
If current projections hold, this heatwave could test:
- Infrastructure
- Public health systems
- Economic resilience
