SA Expands Early Warning Network as SAWS and Santam Partner to Combat Escalating Climate Disasters

In a joint statement issued on Thursday, SAWS and Santam highlighted mounting evidence that climate-related extreme weather events are becoming more intense and more frequent across South Africa.

In a major move to strengthen South Africa's climate resilience and disaster preparedness, the South African Weather Service (SAWS) and insurance giant Santam have announced a strategic partnership aimed at enhancing the country's early warning systems and weather forecasting capabilities amid increasingly severe climate-related disasters.

The partnership includes the installation of nine new Automatic Weather Stations (AWSs) across key high-risk regions of the country to improve weather monitoring, forecasting accuracy and public warning systems.

Officials say the initiative comes at a critical time as South Africa experiences growing climate volatility marked by increasingly frequent floods, storms, fires and extreme rainfall events that have caused widespread destruction and billions of rands in economic losses.

Severe Weather Increasing Across South Africa

In a joint statement issued on Thursday, SAWS and Santam highlighted mounting evidence that climate-related extreme weather events are becoming more intense and more frequent across South Africa.

The country has witnessed repeated episodes of:

• Flooding

• Severe storms

• Wildfires

• Disruptive rainfall

• Infrastructure damage

• Loss of life

One of the most devastating examples cited was the KwaZulu-Natal floods of 2022, which caused an estimated R50 billion in damages and left hundreds dead while destroying critical infrastructure and homes.

Experts warn that climate change is increasing both the frequency and intensity of such weather-related disasters across Southern Africa.

Early Warning Systems Seen as Critical Disaster Prevention Tool

Authorities stressed that early warning systems are now an essential component of disaster risk management and public safety.

According to the joint statement, effective warning systems help communities prepare for incoming hazards, reducing both casualties and economic losses.

"Early warning systems are not a luxury but cost-effective tools to enhance preparedness, save lives and reduce economic losses," the statement said.

However, despite improvements in meteorological capabilities, significant observational gaps still exist across several regions of South Africa.

These gaps can weaken forecasting accuracy and reduce the ability of authorities to provide timely localised warnings during severe weather events.

Santam Funds Nine New Automatic Weather Stations

As part of the partnership, Santam has sponsored the installation of nine Automatic Weather Stations to strengthen the SAWS observation network.

The rollout includes:

• Four AWS units installed in Limpopo and Mpumalanga during pilot phases in 2021 and 2022

• Five newly commissioned stations in:

  • KwaZulu-Natal

  • Eastern Cape

  • Western Cape

  • Gauteng

All stations are now fully operational and integrated into the national SAWS weather observation network.

The new systems provide real-time weather data essential for:

• Forecasting

• Flood prediction

• Storm monitoring

• Climate analysis

• Disaster early warning systems

High-Risk Regions Prioritised

Officials said the locations of the new stations were selected through a needs-based assessment conducted by SAWS.

Priority was given to regions experiencing:

• Severe rainfall

• Frequent flooding

• Storm-related disruptions

• Observation infrastructure gaps

Particular focus was placed on the eastern seaboard stretching across:

• Eastern Cape

• KwaZulu-Natal

• Mpumalanga

• North-eastern Limpopo

These regions have experienced repeated extreme rainfall and flood disasters in recent years.

Additional observational gaps were also identified in parts of:

• Western Cape

• Gauteng

SAWS Expands National Weather Monitoring Infrastructure

SAWS Acting CEO Dr Jonas Mphepya described the partnership as an important example of effective collaboration between the public and private sectors.

"In a time of frequent and intensifying severe weather events, the importance of reinforcing our observational infrastructure, which is the bedrock of our weather and climate services, cannot be overemphasised," Mphepya said.

He noted that SAWS currently operates an extensive national observation network including:

• 273 Automatic Weather Stations

• 211 Automatic Rainfall Stations

• 26 Lightning Detection Network Sensors

• 25 Climate Stations

• 12 Meteorological Radar Systems

The additional AWS installations are expected to significantly strengthen forecasting accuracy and localized warning capabilities.

Climate Resilience and Insurance Risk Reduction

Santam Group CEO Tavaziva Madzinga said the partnership reflects a broader effort to build climate resilience and improve disaster preparedness across South Africa.

"By strengthening observation and forecasting capabilities, we are helping to ensure that early warnings are accessible, credible and localised, so that South Africans can act before weather hazards escalate into disasters," he said.

Madzinga noted that from an insurance perspective, improved early warning systems can help reduce losses suffered by:

• Households

• Businesses

• Municipalities

• Agricultural sectors

• The broader economy

He added that stronger forecasting systems ultimately help communities avoid preventable damage while improving national resilience against climate-related shocks.

Focus on Public Awareness and Education

Beyond infrastructure investment, the partnership also includes extensive public awareness and education initiatives aimed at helping communities understand and respond to severe weather warnings.

Santam said it is working with:

• Municipalities

• Schools

• Community organisations

• Local radio stations

to improve public understanding of weather risks and emergency response measures.

The awareness programmes include:

• School-based climate education initiatives

• Community radio broadcasts

• Local-language disaster preparedness campaigns

• Public awareness outreach in high-risk areas

Officials believe that warning systems are most effective when communities understand both the risks and the actions required during emergencies.

South Africa Faces Growing Climate Adaptation Challenge

The partnership comes as South Africa faces increasing pressure to strengthen climate adaptation systems amid rising environmental risks.

Climate scientists have warned that Southern Africa is likely to experience:

• More extreme rainfall events

• Prolonged droughts

• Heatwaves

• Wildfires

• Coastal flooding

• Infrastructure stress

Experts say investment in forecasting systems, disaster preparedness and resilient infrastructure will become increasingly important for protecting lives and sustaining economic stability.

The SAWS-Santam partnership is being viewed as a significant step toward strengthening South Africa's climate resilience architecture in the face of escalating weather-related threats.
