Traveller notes on Plettenberg Bay in April

Notes from nearby Knysna (30 km away)

Plettenberg Bay doesn't have its own notes for April yet — these are about Knysna, close enough to share the season.

Regulars are specific this marks one of the better windows of the year for the wider region, the harsh summer heat and southeasterly wind both abated by now while the real winter rains haven't started in earnest yet. Our row backs that mild, genuinely dry read, 22C over 15.3C nights, with rain light at 39.1mm across 7.5 days and humidity at 76 percent. Regulars are honest most years bring lovely weather, occasionally warm enough for a swim though usually a bit too cold for that, while other years have brought genuinely dreadful storms during the same stretch. The sea sits at a cool 17.9C. The record: 9.4 hours of sun, a 19.2 kph wind and AQI 25.

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.
