Storms or high winds over the open ocean can generate large waves that trigger high surf in coastal areas. High surf typically impacts the shore in “sets” of three to five waves between lulls. Any wave can be significantly larger than the previous one and can catch beachgoers off guard. Although general forecasts can be made about surf conditions, the timing of individual waves can never be predicted. Please note that PDC Active Hazards layer for high surf currently only covers the Hawaiian Islands at this time.
- Rip currents: Narrow, powerful currents that run perpendicular to the beach and out into the ocean.
- Rogue waves: Solitary waves that rise to unusual height and mass.
Coastal flooding: Flooding that occurs as a result of large, breaking waves.
- Use extreme caution when entering the water, and never turn your back on the ocean.
- Heed ocean safety signs posted at public beaches.
- Be aware of the risks associated with water-related activities.
- If you get caught in a rip current, do not panic or swim against the current. Instead, swim sideways parallel to the beach to get out of the narrow current.
