What to know
Day Island Wall is a near-vertical wall near the south end of the Tacoma Narrows. Local divers rate it among the best shore dives in the Sound, and it is also one of the most demanding.
The current here is strong. The dive only works in the short window around slack water, so you need to know how to read the tables and how to bracket slack. If you have not dived it before, go with someone who has.
The depths are real depths: plan gas, decompression limits and your ascent with care, and keep your buddy within reach.
Plan the dive
Slack-tide windows for Day Island Wall are predictions, not observations. Check the water yourself before every dive.
