If you’re travelling through South Africa between 13 and 16 May 2025, especially in the northwestern parts of the country, be aware: a heatwave alert is now in effect.

According to the South African Weather Service (SAWS), these regions will experience extremely high temperatures with minimal relief, making heat-related illness a real risk for travellers on the move.

The alert covers areas in the northwestern interior, where soaring daytime temperatures can pose serious health dangers, particularly for those exploring remote or outdoor attractions. Whether you’re road-tripping, hiking, or sightseeing, understanding the signs of dehydration and heatstroke could be lifesaving.

How travellers can stay safe

Dress wisely: Choose light-coloured, loose-fitting clothing and wide-brimmed hats to shield yourself from direct sun.

Know where to cool off: Identify air-conditioned stops along 222your route, such as cafés, shopping centres, or accommodation with proper ventilation.

Use sun protection: Apply SPF 30+ or 50+ sunscreen frequently and wear UV-protective sunglasses.

What To Do If You Feel Unwell

If you suspect heat exhaustion:

Move to a shaded or air-conditioned space.

Lie down, elevate your feet, and drink cool fluids.

Loosen clothing and place cool, damp cloths on your body.

If heatstroke symptoms are present:

Call emergency services immediately (10177 or 112).
