In recent weeks, South Asia has been grappling with an unprecedented heat wave, with temperatures soaring to record highs in both Pakistan and India. This extreme weather event has had severe impacts on daily life, health, and infrastructure, making it crucial to understand how to cope and survive during such harsh conditions.
In this post, we will discuss the causes of this heat wave, its effects, and practical survival tips to help you stay safe and healthy.
The Heat Wave: An Overview
The heat wave in South Asia has brought temperatures exceeding 45°C (113°F) in many cities of India, Pakistan and Banglades with some areas experiencing even higher temperatures. Pakistan’s Sindh province and India’s Rajasthan have been particularly hard-hit, with heat indexes reaching dangerous levels resulting in a few deaths due to heat stroke. The combination of high humidity and scorching temperatures has led to a critical situation, putting millions at risk of heat-related illnesses.
Forecast for next week
The heat wave continues to affect large parts of South Asia, with particularly high temperatures in both Pakistan and India. The maps indicate sustained high temperatures across the region this whole weak, with inland areas experiencing extreme heat.
Pakistan
- Sindh and Balochistan: Temperatures are expected to remain very high, with several regions showing temperatures above 45°C. The cities of Karachi, Hyderabad, and Sukkur are going to experience severe heat.
- Punjab: Lahore and surrounding areas also show temperatures ranging from 42°C to 45°C.
- North: The northern areas are slightly cooler but still experiencing significant heat, with temperatures around 35°C to 40°C.
India
- Northwest India: Rajasthan, Gujarat, and parts of Maharashtra are seeing extremely high temperatures, often exceeding 45°C. Cities like Jaipur, Jodhpur, and Ahmedabad are particularly affected.

- South India: Karnataka, Andhra Pradesh, and Tamil Nadu are also quite hot, though temperatures are slightly lower, ranging from 30°C to 40°C.
Causes of the Heat Wave
- Climate Change: One of the primary factors contributing to the intensity and frequency of heat waves is climate change. The rising global temperatures have led to more extreme weather patterns, including prolonged heat spells.
- Urbanization: Rapid urbanization has resulted in the creation of heat islands, where concrete and asphalt absorb and retain heat, making cities significantly warmer than rural areas.
- El Niño Effect: The El Niño phenomenon, characterized by the warming of the Pacific Ocean, has been linked to extreme weather events worldwide, including heat waves in South Asia.
Impacts of the Heat Wave
- Health Risks: Heat strokes, dehydration, and other heat-related illnesses have surged, overwhelming healthcare systems. Vulnerable populations, such as the elderly, children, and those with pre-existing health conditions, are particularly at risk.
- Water Shortages: The extreme heat has led to increased water consumption, straining already scarce water resources. Many areas are experiencing water shortages, exacerbating the crisis.
- Power Outages: The high demand for electricity to power air conditioners and fans has led to frequent power outages, leaving many without a means to cool down.
- Agricultural Damage: Crops have withered under the intense heat, threatening food security in the region.
Survival Tips for Extreme Heat
Heat waves can be extremely dangerous and it’s crucial to take appropriate measures to protect yourself and others. Here are some comprehensive tips to help you survive during extreme heat conditions:
