Western Cape

The Western Cape wraps the south-western tip of Africa where the cold Benguela current up the Atlantic side meets the warm Agulhas current sweeping down the Indian Ocean side. Cape Town sits on the Atlantic shore of the Cape Peninsula with Table Mountain at its back; Cape Point at the south of the peninsula is where the two ocean systems brush past each other, not the textbook meeting line at Cape Agulhas a hundred and fifty kilometres east but close enough that the contrast in water temperature between Camps Bay on the Atlantic and Muizenberg on False Bay can run ten degrees on the same afternoon. The tide here is a moderate semidiurnal signal: mean range at the Cape Town harbour gauge is about 1.4 metres, with two highs and two lows of comparable size about twelve and a half hours apart, climbing past 1.8 metres on the largest spring tides and dropping near 0.9 on neaps. The defining local wind is the Cape Doctor, a south-easter that sweeps down off Table Mountain through the summer and pushes the surface water offshore on the Atlantic side, dropping inshore sea-surface temperatures to single digits even in February. The Two Oceans Aquarium at the V&A Waterfront runs a tidal-pool exhibit that exchanges water with the harbour each cycle. Surf at Muizenberg, kelp-forest dives off Cape Point, snorkel sites in the False Bay marine protected area, the long sand at Noordhoek and Long Beach Kommetjie, and the rock pools at St James and Kalk Bay all read the table for different windows. The South African Navy Hydrographic Office (SANHO) is the authoritative source for tide tables; Open-Meteo Marine drives the gridded predictions on this site.
