Understand the risk
Wind, swell direction, wave period and local exposure interact. A lull between larger sets can create a misleading impression. Forecasts describe an area; the actual entry and exit still need assessment.
Reading weather and swell: what connects
Forecast
Regional outlook
- Check updates and warnings
Observation
Actual entry and exit
- Watch changing sets
Local advice
Site-specific effects
- Ask a qualified local operator

Put the knowledge into practice
Check current Bureau forecasts and warnings, then obtain local advice. Observe the site long enough to understand the pattern and identify exits. Cancel or choose another location when conditions exceed the team’s ability.
