Reading a marine forecast
Look beyond the weather icon: wind direction, swell period and visibility shape the actual dive.
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
A calm-looking beach may have surf from a distant storm. Compare the hourly wind with the swell's direction and period; ask the local operator how that combination behaves at the entry.
A practical approach
Check the updated forecast on dive day, set a cancellation threshold with your buddy and turn back if conditions differ from the briefing.
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
