Key Takeaways
- The South African Weather Service (SAWS) has issued multiple yellow‑level warnings for damaging winds and waves along the Eastern Cape and KwaZulu‑Natal coasts.
- Yellow Level 2 warnings cover damaging winds (East London – Port Edward) and damaging waves (Tsitsikamma – Port Edward); a Yellow Level 1 warning applies to winds and waves from Port Edward to Kosi Bay.
- Very cold conditions are expected over the northern interior of the Eastern Cape, with temperatures near freezing in parts of the Eastern Cape, Northern Cape and Free State.
- In SAWS’s colour‑coded system, yellow indicates a moderate risk that warrants caution; numbers denote likelihood (Level 2 = high, Level 4 = low, Level 6 = high).
- Provincial forecasts show cool to cold mornings with fog in many interior areas, mild to warm daytime highs in the north‑east, and fresh to strong southeasterly/southwesterly coastal winds.
Overview of SAWS Weather Warnings
The South African Weather Service has activated several yellow‑level alerts for the Eastern Cape and KwaZulu‑Natal coastline, warning of damaging winds and high waves that could affect settlements, small vessels, and beachfront activities. These alerts are part of SAWS’s impact‑based warning system, which uses colour codes to convey risk levels and numbers to indicate the probability of impacts occurring. The current warnings are classified as yellow, signalling a moderate risk that requires heightened awareness and precautionary measures from residents, mariners, and local authorities.
Yellow Level 2 Warning – Damaging Winds (East London to Port Edward)
A Yellow Level 2 warning for damaging winds is in effect for the coastal stretch between East London and Port Edward. The forecast anticipates localized damage to settlements and temporary structures, possible disruption to power and communications networks, and interruptions to beach and port activities. Because the likelihood of these impacts is high (Level 2), communities in this zone should secure loose objects, avoid unnecessary travel, and prepare for potential power outages or communication hiccups.
Yellow Level 2 Warning – Damaging Waves (Tsitsikamma to Port Edward)
Simultaneously, a Yellow Level 2 warning for damaging waves covers the coastline from Tsitsikamma through to Port Edward. Small boat operators face increased navigation difficulties, with a risk of vessels taking on water or capsizing. The warning emphasizes that even experienced mariners should exercise extreme caution, consider postponing voyages, and ensure safety equipment is readily available. Beachgoers are advised to stay clear of the water’s edge where wave action may be unusually strong.
Yellow Level 1 Warning – Winds and Waves (Port Edward to Kosi Bay)
Between Port Edward and Kosi Bay, a Yellow Level 1 warning expects localized disruption of small harbours or ports for short periods, small vessels at risk of taking on water or capsizing, and general difficulty in navigation. Although the likelihood of impacts is lower than for Level 2 warnings, the system still urges caution: harbour authorities may implement temporary restrictions, and recreational users should monitor conditions closely before heading out.
Very Cold Conditions Across the Interior
In addition to coastal hazards, SAWS forecasts very cold temperatures over the northern interior of the Eastern Cape, with parts of the Eastern Cape, Northern Cape and Free State nearing freezing. These conditions could affect agriculture, water supplies, and outdoor labour. Residents are encouraged to dress in layers, protect vulnerable plants and livestock, and ensure heating systems are functional.
Explanation of SAWS Colour‑Coded Warning System
SAWS uses a colour‑coded approach where yellow denotes a moderate risk that necessitates caution and awareness, while orange signals a higher‑risk scenario demanding increased preparation. The numeric suffix (e.g., Level 2, Level 1) reflects the likelihood of the weather‑based impact occurring: Levels 2 and 6 indicate a high probability, whereas Level 4 indicates a low probability. This dual‑code system helps the public and decision‑makers gauge both the severity and the chance of adverse effects.
Provincial Forecast – Gauteng
Gauteng is expected to experience morning fog in some areas, otherwise partly cloudy and cool, with warmer conditions in the northern parts. Temperature ranges are: Pretoria 12 °C – 23 °C, Johannesburg 11 °C – 22 °C, Vereeniging 9 °C – 20 °C. Light winds and limited precipitation are anticipated, making it a relatively stable day for outdoor activities, though fog may reduce visibility early in the morning.

Expected temperatures: Bloemfontein 2 °C – 16 °C, Welkom 6 °C – 19 °C, Bethlehem 6 °C – 17 °C. The cold start may lead to frost in low‑lying areas, so farmers and residents should take precautions against freezing conditions.

Temperature ranges are similar to the western half, with particularly low minima in the northern interior (e.g., Komani 2 °C – 12 °C). Residents should guard against frostbite and ensure heating sources are safe and operational.
Provincial Forecast – KwaZulu‑Natal
KwaZulu‑Natal will see morning fog over the interior, otherwise partly cloudy and cool, turning cold in the extreme south‑west.

The cooler temperatures in the south‑west may bring a chill to beachgoers, while the interior remains mild.
Closing Safety Advice
Overall, the prevailing weather pattern calls for heightened vigilance along the Eastern Cape and KwaZulu‑Natal coasts due to damaging winds and waves, and for warm clothing and frost precautions in the interior regions where temperatures approach freezing. Mariners should heed the small‑craft advisories, secure vessels, and avoid venturing out unless necessary. Coastal residents are urged to protect property from wind‑driven debris and to stay informed through official SAWS updates. By following these recommendations, the public can mitigate risks associated with the current weather system.
