South Africa regularly experiences heatwaves, particularly in the interior regions. With temperatures sometimes exceeding 40°C, knowing how to protect yourself is essential.
Understanding Heatwaves
A heatwave is declared when temperatures exceed normal averages by 5°C or more for three consecutive days. High-risk areas include:
- Northern Cape (Upington regularly exceeds 40°C)
- Limpopo Province
- North West Province
- Interior Gauteng
Health Risks
Extreme heat can cause:
- Heat exhaustion: Heavy sweating, weakness, cold/pale skin, nausea
- Heat stroke: High body temperature, confusion, no sweating, rapid pulse (medical emergency)
- Dehydration: Thirst, dark urine, dizziness, fatigue
Staying Safe
Hydration:
- Drink water regularly, even if not thirsty
- Avoid alcohol and caffeine
- Eat water-rich foods like fruits
Activity:
- Limit outdoor activities during 10 AM - 4 PM
- Exercise early morning or evening only
- Take frequent breaks in shade or air conditioning
Protection:
- Wear light-colored, loose-fitting clothing
- Use SPF 50+ sunscreen
- Wear a wide-brimmed hat and sunglasses
Vulnerable Groups
Take extra care with:
- Elderly individuals
- Infants and young children

Never Leave Children or Pets in Cars
Car interiors can reach 60°C in minutes, even with windows cracked. This is a leading cause of heat-related deaths.
