SA Braces for Heatwave: Amber Alerts Issued as Temperatures Soar to 34°C

South Africa is gearing up for a significant heatwave as a high-pressure system settles over the region, bringing scorching temperatures that could reach 34°C in some areas. The South African Weather Service (SAWS) has issued Amber level alerts, urging residents to take precautions and stay hydrated.
This heatwave follows a pattern seen across Europe, where extreme heat has been building in countries like Spain, Portugal, and France. France, in particular, has experienced record-breaking temperatures, with the city of Nimes registering an unprecedented 41.8°C (107°F) on Sunday – the highest August temperature ever recorded. Red extreme heat warnings remained in effect across southwestern France through Monday and Tuesday, highlighting the severity of the situation.
What to Expect in South Africa
The Amber alert signifies a high probability of disruptive conditions. While not as severe as a Red alert, it still warrants caution. South African residents, especially those in vulnerable groups like the elderly, young children, and those with pre-existing health conditions, are advised to:
- Stay Hydrated: Drink plenty of water throughout the day, even if you don't feel thirsty.
- Seek Shade: Avoid prolonged exposure to direct sunlight, especially during peak hours (11:00 AM - 3:00 PM).
- Limit Strenuous Activity: Reduce physical exertion during the hottest parts of the day.
- Check on Vulnerable Individuals: Ensure that family members, friends, and neighbours who may be at risk are safe and comfortable.
- Never Leave Children or Pets in Vehicles: Temperatures inside a parked car can rise rapidly, posing a life-threatening risk.
Why is this happening?
The current heatwave is attributed to a strong high-pressure system dominating the weather pattern over central Europe and now extending its influence over South Africa. High-pressure systems are associated with clear skies, calm winds, and, crucially, rising temperatures. As the air descends within the high-pressure system, it warms and dries, contributing to the hot conditions.
Looking Ahead
The SAWS will continue to monitor the situation closely and provide updated forecasts and warnings. Residents are encouraged to stay informed and heed any official advice. While the heatwave is expected to persist for several days, forecasters anticipate a gradual easing of temperatures towards the end of the week. However, it serves as a reminder of the increasing impact of climate change and the importance of preparing for more frequent and intense heat events.
Stay safe and stay cool, South Africa!
