No. It is a warm-temperate to subtropical island. Visibility and soft-coral colour are seasonal, not a Maldives lagoon. Haenyeo work is older than tourism. As a visitor destination Jeju adds a 2007 UNESCO volcanic listing, a 2010s Seogwipo dive-shop cluster, and a 2016 heritage listing that made the women divers a public sentence, for better and worse.
Jeju as a destination is a 2016 heritage plaque wearing a ferry ticket. The work is older than both. Summer snorkel visitors need a sealing mask and a rash top or shorty. Autumn and winter divers need real rubber or a drysuit. Boats supply tanks.

The method is a calm Udo or Hamdeok snorkel, or a Seogwipo checkout, then Munseom or Beomseom when swell and cards match. Haenyeo coasts are workplaces. Harm clusters on swell at the islets, cold-water shock outside high summer, Seogwipo boat traffic, and treating a haenyeo ground as empty. This is not medical advice.
These are famous, mapped sites. Wind and season change; harbours publish the day. Depths are typical published bands, not a live plan. Jeju is two famous islets, a ferry island and a working coast. The volcano on land is the same story.
