This is a model, not a chart and not advice. The weights in it are estimates that have never been fitted against real dives. It can be confidently wrong about visibility, about conditions and about where fish are.
It does not know the law. Minimum sizes and closed seasons exist for only 5 of the 164 jurisdictions it covers. Everywhere else it shows no legal information at all, and that means unknown, never permitted.
It does not reliably know where you may not fish. Protected areas come from OpenStreetMap and its marine coverage is incomplete. A spot shown inside a reserve is entirely possible.
Breath-hold diving kills experienced people. Shallow water blackout gives no warning and drowns silently. Never dive alone, never hyperventilate, and always dive with someone watching you on the surface.
You are responsible for your own safety and for knowing the rules where you dive. Verify everything with the local authority before you get in the water.
Everything here is built from free, public data. Where a licence requires attribution, this is it.
Protected areas are from OpenStreetMap, not the WDPA. Marine coverage is incomplete. The absence of a mask is not evidence that there is no reserve.
Usage counting. If a counting endpoint is
configured, this page reports one short request per view: a page
path, the title and the referring site. No cookies, no
identifiers, no tracking between visits, and never any
coordinates — a point forecast is reported as
/point, never as the latitude and longitude in the
address bar. Do Not Track and Global Privacy Control are honoured.
Nothing is sent if no endpoint is configured.
This is model output. It is not a nautical chart, not a tide table and not legal advice. Verify everything locally before you dive.
