Traveller notes on Plettenberg Bay in March

Notes from nearby Knysna (30 km away)

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

Asked to choose a month for the Cape and the Garden Route, regulars answer March without much hedging: February and March are the good pair, long days and very little rain, and they suggest three to five days for the route rather than a night in each town. Our row supports the dry half at 43.7mm across 8.7 days with 10.5 hours of sun, but it is cooler than their description - 23.9C days over 17.7C nights, pleasant rather than hot. The sea is the real surprise and the thing to plan around: 18.3C, cold enough that the lagoon and the forest walks, not swimming, are what the month is for. The record: humidity 79 percent, a 20.2 kph wind and AQI 26, among the cleanest air in this collection.

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.
