40°C heat warning: These areas face extreme temperatures

The South African Weather Service (SAWS) has warned residents in parts of the Northern Cape and Western Cape to prepare for very hot to extremely hot and uncomfortable conditions, with temperatures expected to reach 40°C.

The advisory is valid from 11:00 on Monday, 9 November, until 20:00 on Tuesday, 10 November.

Which areas are at risk of extreme heat?

SAWS expects daytime temperatures of between 36°C and 40°C in the Namakwa District of the Northern Cape and the interior of the Western Cape.

While these areas face extreme heat, the eastern parts of the country will remain cloudy and cool on Monday.

However, much of the country should see fine, warm to hot conditions from Tuesday through Thursday

Isolated to scattered showers and thundershowers are expected to return over the eastern interior from Friday and continue into the weekend.

Extreme heat could pose a health risk

SAWS warns that extremely high temperatures can reduce the body’s ability to cool itself through sweating.

This can lead to hyperthermia, a condition in which the body becomes dangerously hot.

Heatstroke is one of the most serious heat-related conditions and can kill without immediate medical attention.

People who spend long periods outdoors or undertake strenuous activities during the hottest part of the day should take extra care.

How to protect yourself

SAWS advises residents to:

• Drink plenty of water and take precautions against heat exposure.
• Avoid spending long periods in direct sunlight.
• Stay in shaded or cool areas where possible.
• Carry an umbrella when outdoors during the hottest part of the day.

Residents should also watch for signs of heat-related illness and seek urgent medical help if someone shows symptoms of heatstroke.
