How to read this forecast
The median is the middle of the modelled distribution: half the ensemble members came out clearer, half murkier. The 80% interval is the spread between the 10th and 90th percentiles — a wide band means the weather models disagree about the swell or wind that will stir the bottom, not that the site is unpredictable in itself.
P(diveable) is the share of ensemble members whose worst safety gate still clears at the best daylight hour. The limiting factor names which gate binds first — entry and exit, bottom surge, current, wind or surface chop. A site can have beautiful water and still be undiveable because the entry is unworkable.
