Extreme weather events, such as heat waves, are becoming increasingly common due to climate change. These prolonged periods of intense heat can pose serious risks to health, disrupt daily life, and even lead to fatalities. Staying informed and taking preventive measures are key to staying safe during these challenging conditions.
In this guide, we provide practical tips to help you and your loved ones stay safe during extreme weather, especially during heat waves.
Heat Waves
A heat wave is a type of extreme weather characterized by abnormally high temperatures lasting for several days. In South Africa, a heat wave is officially declared when temperatures are significantly above the norm for three consecutive days.
These events can exacerbate health risks, especially for vulnerable groups like the elderly, children, and those with chronic illnesses.
Why Are Heat Waves Dangerous?
- Heat Exhaustion: Heavy sweating, dizziness, and fatigue can escalate into serious health issues.
- Heat Stroke: When the body fails to cool itself, it can result in life-threatening conditions.
- Dehydration: Extreme heat causes excessive fluid loss, leading to organ strain.
- Environmental Risks: Extreme weather can trigger secondary hazards like wildfires.
Quick Checklist for Extreme Weather Safety
- Monitor weather updates and heat advisories.
- Prepare an emergency kit with water, food, and cooling tools.
- Avoid outdoor activities during peak heat hours.
- Check on vulnerable family members and neighbors.
Heat Wave Readiness
1. Stay Informed
- Monitor Weather Alerts: Keep track of extreme weather advisories from reliable sources like the South African Weather Service (SAWS).
- Understand Local Risks: Be aware of how extreme weather, like heat waves, might impact your area.
2. Prepare Your Home
- Insulate Against Heat: Use reflective blinds or heavy curtains to block out sunlight.
- Stock Essentials: Include water, non-perishable foods, and cooling aids in your emergency kit.
- Create Cool Zones: Identify the coolest parts of your home where you can retreat during extreme weather.
3. Plan for Potential Power Outages
Heat waves can strain power grids, causing blackouts.
- Backup Devices: Keep battery-powered fans or lights ready.
- Charge Electronics: Fully charge your devices before the heat wave peaks.
Surviving Extreme Heat Waves
1. Keep Cool
- Stay Indoors: Avoid going outside during the peak heat hours (11 a.m. to 3 p.m.).
- Use Cooling Tools: Fans, air conditioners, and wet towels can help regulate your body temperature.
- Cold Water Therapy: Take cool baths or showers to combat rising body heat.
2. Stay Hydrated
- Drink More Water: Aim to drink 8-10 glasses of water daily, even if you’re not thirsty.
- Avoid Alcohol and Caffeine: These can dehydrate you further during extreme weather.
- Eat Water-Rich Foods: Fruits like watermelon, oranges, and cucumbers are great options.

2. Share Resources
- Distribute bottled water and information about coping with extreme weather in underserved areas.
3. Spread Awareness
- Use social media to share tips and resources for dealing with heat waves and other forms of extreme weather.
Recognizing and Responding to Heat-Related Illnesses
Knowing the symptoms of heat-related illnesses can save lives during extreme weather.
Symptoms to Watch For
