Pakistan's Record Heat and Food Crisis: What's at Stake This Summer

Pakistan is facing a new normal. On May 29, 2026, the Pakistan Meteorological Department (PMD) recorded a temperature of 51.5°C in Dadu District in Sindh Province — nearly 5 degrees Celsius above what's typical for this time of year. But this single number tells a larger story: extreme heat is no longer a seasonal shock to Pakistan. It is becoming the pattern.

That record is not an accident. The National Disaster Management Authority (NDMA) warned back in April that temperatures could reach 52°C across parts of South Punjab, Upper Sindh, and Balochistan — regions that have always been Pakistan's hottest. What's changed is how often we're hitting those peaks, and what that means for the people living there.

A Heat Wave Spreading Across the Country

The PMD has issued an official heatwave alert for June 7–12, 2026, predicting temperatures between 48–51°C across much of Pakistan's interior: cities like Sukkur, Jacobabad, Larkana, and Dadu. At the same time, PMD forecasts show temperatures of 41–46°C in northern cities like Peshawar and Mardan, and 40–43°C in Karachi, the country's largest city, from June 8–12.

This isn't just one region in trouble. It's spread across the country — from Khyber Pakhtunkhwa in the north to Balochistan in the southwest, and down to Sindh in the southeast. That scale matters.

Dadu: Pakistan's Hottest Spot

Dadu District is at the center of this crisis. The district has already endured a series of climate pressures: extended droughts, unpredictable monsoons, water shortages, dust storms, and the threat of sudden glacier-fed floods. A temperature of 51.5°C is extreme, but for Dadu, it's an extension of a crisis that's been building for years.

Here's where the science becomes personal: the human body has limits. There's a measurement called wet-bulb temperature that factors in both heat and humidity. When wet-bulb temperatures reach about 35°C, even a healthy person resting in the shade will begin to suffer heat stroke. Once it goes above that, the human body simply cannot cool itself down. Parts of Sindh have come close to or briefly exceeded this level in recent years. A dry temperature of 51.5°C, even in Sindh's low-humidity interior, leaves almost no margin for error.

The people at greatest risk are those who work outdoors in agricultural labor, the elderly, children, and those already undernourished — populations that make up a large part of Dadu's rural workforce. For them, this heat is not just uncomfortable. It is life-threatening.

The Monsoon Problem

Here's where things get complicated. The PMD's seasonal forecast includes a warning: El Niño conditions — a climate pattern driven by warming in the Pacific Ocean — are likely to develop during Pakistan's 2026 monsoon season. The last time El Niño was strong, it suppressed the monsoon rains across South Asia.

This matters because Pakistan depends on monsoon rains to cool the country down and refill water supplies. If El Niño weakens the monsoon, as the PMD is warning, Pakistan won't get the rainfall relief it normally does. Instead, the hot season would stretch longer, soil moisture wouldn't recover, and farms would face even more stress.

The broader context here is instructive. In 2022, Pakistan experienced extreme spring heat followed by a catastrophic monsoon failure that culminated in devastating floods. The sequence — heat, then failed rains, then too much rain — created cascading humanitarian and agricultural failures that took years to recover from. The structural risk now is that 2026 could follow a different but equally damaging pattern: sustained heat combined with below-normal rainfall, extending the agricultural stress season.

The Food Security Layer

The real danger lies not in the heat alone but in the combination of heat and hunger. In February 2026, a report using the IPC (Integrated Food Security Phase Classification) system, cited by UN News, found that 7.5 million people in Pakistan face serious food insecurity and malnutrition. Of those, about 1.25 million were classified in IPC Phase 4 — an emergency level — between December 2025 and March 2026. That classification means large gaps in food supply and rates of acute malnutrition high enough to be a medical concern.

Looking forward, the same analysis projected that 6.7 million people will face high or worse levels of food insecurity between April and September 2026. That window — starting now — covers both the current heatwave and the monsoon season that could either ease or worsen the agricultural shortfall.

Extreme heat damages food security in multiple ways at once: it reduces crop yields as wheat and other early crops struggle under the stress; livestock die from heat exposure; agricultural workers can't labor as long in extreme temperatures; and people's bodies demand more calories just to keep cool under heat load. For populations already facing food shortages — IPC Phase 3 and Phase 4 — any one of these impacts is destabilizing. All of them happening together, over weeks or months, tests a system with very little capacity to absorb shock.

The Ministry of Climate Change has warned that temperatures could rise by 6 to 8 degrees Celsius above average if current trends continue. If that happens, today's record temperatures would look moderate by comparison.

The Challenge of Response

The NDMA did issue its heat warning back on April 27 — more than a month before Dadu's record temperature. That suggests Pakistan's forecasting system is working and early warnings are reaching decision-makers. Whether that warning actually translates into action at the local level — in districts and towns — is a harder question.

Heat emergencies are different from floods. When a flood comes, it's visible and urgent. Everyone sees the water and evacuates. Heat deaths happen quietly, one person at a time, across thousands of locations, and they're often recorded as something else — a heart attack, illness, or old age. They don't trigger the same visible emergency response. Pakistan's disaster management system has improved since major institutional reforms after the 2010 floods, but heat still poses a different challenge.

Jacobabad, one of the cities now under the PMD alert, has become a reference point in global climate science because of how often its wet-bulb temperatures exceed the survivability threshold. That it reappears on this alert list surprises no one who studies Pakistan's climate. The problem is this: knowing that a district is chronically exposed to dangerous heat hasn't yet translated into the infrastructure that would actually save lives — widespread cool shelters, reliable electricity for fans in rural areas, organized water supply chains, or labor policies adjusted for extreme heat.

What Happens Next

Over the next few weeks, three things will determine how bad Pakistan's summer becomes. First, whether this heatwave extends beyond the June 7–12 window. Second, how moisture patterns develop as the pre-monsoon season transitions to monsoon. Third, whether the PMD's warning about El Niño and below-normal rainfall actually happens.

For the 1.25 million people already in food emergency and the millions more facing serious shortages, the margin for error is essentially zero. There is no buffer.

The broader context here is that international humanitarian organizations working in Pakistan should not treat the heat crisis and the food crisis as separate problems happening to arrive at the same time. They are interconnected. The heat is not coming before the food shortage. It is arriving as part of it, making it worse. Both need to be managed as a single compound crisis, not as independent events assessed one at a time.
