No operation notices right now
Naoshima has no bridge — every trip on or off the island is a ferry, and fog, strong wind and typhoons do cancel them. This page pulls Shikoku Kisen's own operation notices together with the wind and fog on each crossing, so you can see the weather coming and check the official word before you set out.

The official word
Shikoku Kisen posts cancellations (欠航) and planned typhoon suspensions (計画運休) to this page, usually the evening before or the morning of a disruption. It is the authoritative word — this tool links straight to it.
Wind and visibility are open-water model forecasts for each crossing, not readings from a boat — conditions near the shore and in the channels differ, and the figures come on a coarse (~25 km) grid. The wind follows the Beaufort scale and the visibility the WMO/NWS fog scale; they describe the air and water, and are never a judgement that a crossing will run or is safe.
