Settle.

Viz is a memory,
not a forecast.

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.

Import history

one line per dive

Paste past dives, one per line — date, time, site, visibility. Order does not matter and the parser is lenient: 2025-06-14, 09:00, Buffels, 6 and 2025/07/02 14h bakoven 3.5 both work. Each dive gets its own ten days of archived swell and wind pulled from ERA5, so the fit is reproducible.

These are my guesses about your sites, and they are the weakest part of the model. Move them until the output matches dives you remember, or log dives and let the fit move the ones it can actually see. Anything you change here becomes the prior the fit starts from.
