SA Weather Guide: How to Get Official Weather Forecasts, Warnings and Safety Tips
Weather affects everyone, from planning your day and your commute to preparing for severe storms, heatwaves or flooding. Rather than relying on scattered automated posts, this guide explains how weather forecasting works in South Africa and shows you how to access authoritative weather updates and warnings from the official source, the South African Weather Service (SAWS).
What is the South African Weather Service (SAWS)?
The South African Weather Service is South Africa’s official national meteorological authority responsible for weather forecasting, warnings and climate services. It provides forecasts, severe weather warnings and climate information to the public, government departments, disaster management teams, businesses and media.
SAWS operates as a government-owned entity under the oversight of environmental authorities and maintains weather stations and monitoring systems across the country.
Why official weather information matters
Weather forecasts and warnings can affect critical decisions — from travel plans to safety preparations for severe storms or heatwaves. SAWS is the only authoritative and legally recognised source for weather warnings in South Africa, and its information should be prioritised over social media posts or unauthorised platforms.
Government agencies also remind the public to verify weather information through SAWS channels to avoid unverified and potentially incorrect forecasts circulating online.
How to get official weather forecasts and warnings
The primary source for official weather information is the SAWS website, where you can find:
- Seven-day weather forecasts for cities and towns across South Africa
- Minimum and maximum temperatures
- Weather conditions like rainfall, thunderstorms or heat
- Severe weather warnings issued by SAWS

Weather warnings
South African Weather Service issues impact-based severe weather warnings that indicate potentially dangerous conditions such as:

- Snow and cold conditions in relevant regions
These warnings are continually updated and categorised to help the public understand the level of risk and take appropriate action.

Understanding weather warning
South African Weather Service uses a colour-coded and impact-focused warning system to help people prepare ahead of severe weather:
- Yellow — Be aware: Conditions may be hazardous
- Orange — Be prepared: Higher likelihood of significant impacts
- Red — Take action: Extreme conditions that require immediate response
Each level reflects the potential severity and impacts of the weather event across affected regions.
How weather forecasting works in South Africa
Weather forecasting combines data from ground stations, satellite feeds, radar and modelling systems. South African Weather Service continuously analyses this data to provide:
- 7-day forecasts
- Seasonal outlooks
- Climate summaries
- Severe weather warnings and impact assessments
Forecast accuracy generally improves closer to real time, but even long-range forecasts offer useful guidance when interpreted appropriately.
Safety tips for severe weather
When the South African Weather Service issues a warning:
- Stay informed — check the official South African Weather Service website or app regularly
- Avoid unnecessary travel during severe storms or heavy rain
- Move to safe, higher ground if flooding is forecast
- Secure outdoor objects in high winds
- Listen to local authorities and disaster management guidance
These steps help you stay safe, informed and prepared when weather conditions change.
