Heatwave Alert by SA Weather Service
As South Africa braces for a weekend heatwave, the South African Weather Service (SAWS) has issued a heatwave alert predicting widespread high temperatures across the country. Many regions are set to experience temperatures soaring over 30°C, with some areas climbing to 39°C. Residents are being advised to take precautions, as fire risks and sunburn dangers increase alongside the rising temperatures.
Friday Forecast: Hot Weather Across South Africa
The SA Weather Service reports that the Northern Cape, North West, and Limpopo provinces are likely to see some of the highest temperatures. Cities in these regions could reach highs between 35°C and 39°C on Friday, November 1. Although most of South Africa will experience the heat, the Western Cape and KwaZulu-Natal may stay relatively cooler compared to inland provinces.
Heatwave Impacted Regions:
- Northern Cape
- North West Province
- Limpopo
- Parts of the Free State
Additionally, the SA Weather Service warns of an extremely high fire danger over parts of the Northern Cape, Free State, and North West. These hot, dry conditions, combined with wind in some areas, create ideal conditions for wildfires to spread, especially in open areas with dry vegetation.
High Temperatures Expected Through the Weekend
Beginning on Saturday, November 2, the weekend heatwave is expected to intensify, persisting until Monday. The provinces that will be significantly affected include:
- Limpopo: High temperatures, with the western Bushveld area expected to be particularly hot.
- Mpumalanga: Areas along the escarpment will be warm, with cloud cover in the mornings.
- Gauteng: Partly cloudy but hot in the northern regions.
- Free State: Persistently warm, especially in the central and eastern regions.
Temperatures across these regions are forecasted to remain well above average, with the SAWS advising residents to stay informed of local weather updates, reduce outdoor activity, and stay hydrated.
Weather Warnings and Advisories
SAWS has issued several advisories to help citizens stay safe during the heatwave, as high temperatures can lead to health risks, fires, and water shortages.
1. High Fire Danger Conditions:
With dry and windy conditions expected, the risk of fires will remain high, especially across parts of the Northern Cape, North West, and Free State. Firefighting agencies are on alert, and residents in rural and farming areas are urged to avoid any open flames or activities that could ignite fires.
2. Heatwave Advisory for Limpopo, Mpumalanga, and Gauteng:
SAWS has issued a heatwave advisory for these provinces, warning of persistently high temperatures from Saturday through Monday.
3. UV Radiation Alerts:
The UVB sunburn index is predicted to be “very high” in Gauteng and “extreme” in the Western Cape, meaning residents should take extra caution to avoid sun exposure without proper protection. Prolonged exposure during high UV index times can result in severe sunburn and increase the risk of long-term skin damage.
