| Hazard | Alert Level | Affected Municipalities | Valid From (SAST) | Valid To (SAST) |
| Damaging Waves | Yellow(L2) | Bergrivier, Bitou, Cape Agulhas, Cape Agulhas, Cederberg, City of Cape town, M_George, Hessequa, Kamiesberg, Knysna, Matzikama, Mossel Bay, Nama Khoi, Overstrand, Richtersveld, Saldanha Bay, Swartland, Table Bay | 23/06/21 01h00 | 26/06/21 00h00 |
Discussion: Cold front is expected on Friday morning which will result in strong to near gale (50 to 60km/h gusting 70 to 80km/h) NW/W winds between Lambert’s Bay and Cape Agulhas on Friday afternoon spreading to Plettenberg Bay by the evening. Significant wave heights of 4.5m to 6.5m (SW/W swell) can be expected between Lambert’s Bay and Stilbaai by Friday evening spreading to Plettenberg Bay on Saturday morning. The winds expected to moderate from the west by Friday evening and waves subsiding by Saturday evening north of Cape Point.
Impact: Localised damage to coastal infrastructure as well as anglers and beach-goers on low-level rocks may be at risk of being swept off by large waves. Difficulty in navigation at sea for small vessels and personal watercraft (e.g. kayaks) can be expected. This may lead to vessels taking on water and capsizing in a locality. Localised disruption to small harbours for short periods is possible. Disruption to beachfront activities is likely.
Instruction: Be aware of large unpredictable waves along the coast. Small vessels are advised to seek shelter in harbours, bays or inlets. Be aware of strong rip currents especially during spring tides.
