Traveller notes on Plettenberg Bay in June

Other months in Plettenberg Bay

Plettenberg Bay's forum describes July as about as wintry as the Garden Route gets - chillier and windier than the rest of the year - but posters were quick to add that South Africa's winter isn't a washout: some days hit a sunny 25C, others turn cold, windy and wet, and it genuinely doesn't rain for days on end. A few visitors even reported swimming and wearing short sleeves during a June/July stay when a warm spell lined up. Pack for both extremes rather than assuming either a beach day or a full winter coat is guaranteed.

Forum posters name Plettenberg Bay as one of the better bets on South Africa's eastern stretch for good weather with a lower rain chance in January, though they warn the first two weeks of the month get genuinely busy with South African families on school holiday. Beach options vary by character: Robberg Beach has strong undercurrents but makes a nice walk, Central Beach is calmer and family-friendly with a small lagoon to paddle in, and Lookout Beach offers a sheltered lagoon that changes with the tide. Beyond the beach, posters point to whale and dolphin-watching boat tours, cape fur seal colony visits, bungee jumping and the Robberg Peninsula nature reserve as the main draws for a January visit.
