Cape Town dive visibility was decided
days ago.

Six days of swell and wind history at each site, run through bottom-stirring physics, then allowed to settle three days forward. Every weather model is carried through separately, so what you get is a distribution, not a guess with a decimal point.

Fetching ECMWF, MFWAM, GFS-Wave, GWAM and ICON…

Where this is

chart
Site No-take MPA zone

Zone boundaries transcribed from the Government Gazette notices declaring the Table Mountain National Park MPA and the Betty’s Bay MPA (No. 21948, 29 December 2000), under the Marine Living Resources Act 18 of 1998. Each polygon is the seaward boundary exactly as gazetted, drawn straight; the landward edge is the real coastline and is not traced here, so a site falling outside one is not a legal clearance — verify with SANParks before spearfishing.
