The great thing about diving on CI is that we have access all year round. However, conditions do vary between wet and dry seasons:

Wet Season (November – April): ocean conditions occasionally rough on the Northern side of the island, but we have an alternative launch site on the East side and access to other dive sites. Can be rainy but visibility remains in the 20m. This is also the time the whalesharks and mantas visit these waters.  Average water temperature 29°C.

Dry Season (May – October): ocean conditions are calm in North and West side of the Island. Good visibility. Amazing diversity and less divers. Average water temperature 27°C.

Average maximum air temperature is approximately 28°C all year round, with slightly cooler conditions during July-August. Because of surrounding ocean influence, the relative humidity does not fluctuate seasonally and remains around 80-90%. Water temperatures range from a maximum of 30°C in wet season to a chilly 25°C in the dry season. Most divers are happy with a full- length 3mm suit for much of the year, but if you feel the cold you might want a 5mm or a hood!

While we do experience some quick currents in parts of the island, most of our sites have very predictable and slow water movement. The dive master checks the current prior to briefing, on sites with changeable patterns. Generally we like to ‘go with the flow’ at Wet’n’Dry, so most sites are drift (not return) dives and the boat is waiting for us at the end point.

As Christmas Island is a remote location we prefer to err on the side of caution with conservative dive profiles and lengthy surface intervals. There is currently no decompression chamber on Christmas Island, and although we have excellent medical staff available, we recommend that all visitor’s have dive insurance. Christmas Island Wet’n’Dry Adventures are members of Diver’s Alert Network Asia Pacific (DANAP) who provide Worldwide Emergency Evacuation Coverage and more.

NB: Manager reserves the right to cancel diving if conditions affect safety of divers. Refunds and alternative activities offered.

Every diver has his or her own wish list and style of diving. We try to make your dive holiday the best experience possible. So if you would like to see a particular creature or dive site, just tell us. We always put safety first, but if conditions allow, we will do our best to oblige. The ocean, however, has her own rules so we can’t guarantee we’ll find what you’re looking for! 

Larger groups can still be accommodated by splitting into morning and afternoon sessions, which can cater those in your group that would prefer to have a leisurely start and also those who want to charge forth into the dawn.

A range of refreshments, available at any time onboard, include: Tea, Coffee, Water, Milo, Soft Drinks, Cookies, lollies and Muffins (freshly baked and famously yummy).

Lunch is provided on request. We offer tasty and nutritious food from a variety of culinary backgrounds. Please let us know if you have any special requirements and will try to accommodate them.

Transfers from your accommodation to launch site are available on request. Pick-up is generally at 7:50am. Drop-off by the latest 1:30pm. Giving you plenty of time to explore the island.
