Wave sets and dive timing
The quiet gap between waves may not be the end of the set.
Safety and training
General field notes, not a dive plan. Stay within your training, follow local site rules and the operator’s briefing.
Field observation
Watch several complete series from a safe position before entering or exiting. A long-period swell can arrive in larger groups than short wind waves, changing a shore entry within minutes.
A practical approach
Agree who watches the water while the other diver adjusts equipment; postpone the dive if the exit window is unreliable.
Dive-day checklist
Before you go
- Check local conditions and access rules
- Agree limits and the exit with your buddy
- Stop or change the plan if conditions differ
