Discussion: The warm temperatures, dry conditions and fresh to strong winds could result in the development of runaway and veld/bush fires.

Impact Based Weather Warnings for Western Cape and Namaqua: Yellow level 2: Damaging Waves
| 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, George, Hessequa, Kamiesberg, Knysna, Matzikama, Mossel Bay, Nama Khoi, Overstrand, Richtersveld, Saldanha Bay, Swartland, Table Bay | 22/06/21 – 00h00 | 24/06/21 – 00h00 |
Discussion: Significant wave heights with predominant SW direction of 4.0 to 6.5m between Cape Columbine and Cape Agulhas from Tuesday afternoon, with 5.0m wave heights spreading to Alexander Bay and Plettenberg Bay on Wednesday. Rough and choppy seas are expected for Monday and Tuesday, but high energy and powerful waves from Tuesday night. Although spring high tide is expected on Thursday, tides will already be reaching further up the beachfront throughout the week. Wave heights will subside on Thursday.
Impact: Difficulty in navigation at sea for small vessels and personal watercraft (e.g. kayaks) can be expected (particularly Mon and Tue). This may lead to vessels taking on water and capsizing in a locality. Disruption to beachfront activities is likely. Localised damage to coastal infrastructure is possible mainly on Wed and Thurs. Anglers and beach-goers on low-level rocks may be at risk of being swept off by large waves (Wed and Thur). Localised disruption to small harbours for short periods may result.
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.
