When to go wall diving

Top wall diving destinations around the globe provide the opportunity to wall dive somewhere any time of the year. Many of the destinations can be dived all year, though there are some seasonal variations that are worth considering.

  • The Cayman Islands can be dived all year, though June to October is hurricane season – which can open up dive sites at the south of Grand Cayman that are normally inaccessible.
  • Turks & Caicos can also be dived all year, though winter offers the chance of humpback whale sightings. January to April is the busy season.
  • The Bahamas best dive season is November to May, though the hurricane season of June to October offers the calmest seas.
  • Honduras has little fluctuation in temperature and can be dived all year long. The rainy season of October to January can diminish the water visibility slightly.
  • Any time is a good time to scuba dive Belize and April to June is whale shark season along the southern barrier reef.
  • Hawaii can be dived all year, though fans of humpback whales should visit during December to May.
  • The Egyptian Red Sea has few limits on its dive season and can be dived all year.
  • Komodo, Indonesia has a dry season from April to November and is busy during April to August. The dry season has calmer dive conditions and the reefs are at their most active during July and August when nutrients wash in with rising currents. This does however reduce water visibility.
  • Palau is best dived from November to May, though it can be dived all year.
  • Fiji can be dived all year and has the best visibility from July until December.

Who can try wall diving?

There are some wall dives that are suitable for less experienced divers, such as those found in shallower waters with gently sloping walls. Generally speaking though, wall diving is best suited to more advanced divers because of the depths and currents often involved.

It is advisable to be a deep diver and have a Nitrox certification to get the most out of wall diving.

What wall diving gear do divers need?

A reef hook can be useful for wall diving in strong currents and a dive computer with a depth alarm is advisable.

What diving skills do wall divers need?

Wall diving often involves diving in the open ocean without visual depth markers below, such as the ocean floor. It can be difficult to maintain the right depth whilst wall diving and divers can become disorientated. Good depth awareness and buoyancy control are needed to wall dive safely.

Wall dives are often in areas with strong currents. Divers need to be comfortable and competent at drift diving in such currents. Knowing how to use a reef hook can also be helpful at some dive sites.

Divers should monitor the currents, their depth, and air supply often during wall dives.

What are the main hazards of wall diving?

The main hazards of wall diving are going too deep, having insufficient air, and becoming disorientated. All of which can be prevented with good dive skills and attention during the dives.
