High Surf Advisory Issued for Hawaii’s South-Facing Shores
* Updated June 7, 4:25 AM HST
Honolulu, Hawaii – A High Surf Advisory has been issued for all south-facing shores across the Hawaiian Islands, effective from 6 a.m. Saturday.The National Weather Service reports that a moderate south-to-southwest swell (200 degrees) is generating advisory-level surf conditions. Residents and visitors are urged to exercise caution due to possibly dangerous swimming conditions.
Surf Heights and Expected Impacts
the Advisory specifically impacts the shores of Niʻihau and Kauaʻi and will remain in effect until 6 p.m. on Sunday. Surf heights are predicted to reach between 7 and 10 feet. These conditions are expected to create strong breaking waves and powerful currents, significantly increasing the risk for swimmers and beachgoers.
Moderate impacts are anticipated along the affected coastlines. Powerful waves can easily knock people off thier feet and pull them into deeper water. Always assess the conditions before entering the water.
Understanding High Surf Advisories
A High Surf Advisory indicates that dangerous wave conditions are expected. This does not necessarily mean beaches are closed, but it signifies a heightened risk. in contrast, a High Surf Warning indicates an even greater threat, with larger and more powerful waves expected.
The National Weather Service (NWS) issues these advisories and warnings to alert the public about potential hazards. Heeding these warnings is crucial for safety.
| Alert Level | Wave Height | Potential Impact |
|---|---|---|
| Advisory | 7-10 feet | Strong currents, dangerous swimming conditions |
| Warning | 10+ feet | Very strong currents, extreme hazard to life and property |
Safety Tips for High Surf Conditions
When a high surf advisory is in effect, it’s vital to take precautions. Here are a few essential safety tips:
- Never turn your back to the ocean: Waves can be unpredictable.
- Swim only at beaches with lifeguards: Lifeguards are trained to identify and respond to dangerous conditions.
- Heed all posted warnings and signs: These are there for your safety.
- If in doubt, don’t go out: It’s always best to err on the side of caution.
Pro Tip: Before heading to the beach, check the local news and weather forecasts for the latest updates on surf conditions and advisories. You can also find real-time information on the National Weather Service website.
The Science Behind South Swells
South swells are generated by storms in the Southern Hemisphere, ofen thousands of miles away. These swells travel across the Pacific Ocean and eventually impact the southern shores of the Hawaiian Islands, typically during the summer months.
The angle at which the swell approaches the islands influences the height and intensity of the waves. A direct south swell (180 degrees) usually produces the largest surf, while swells from the southwest or southeast might potentially be slightly smaller.
Did you know? The Coriolis effect, caused by the Earth’s rotation, deflects ocean currents and winds, playing a significant role in the direction and intensity of swells.
As climate change continues to impact weather patterns,understanding and predicting these swells becomes even more significant for coastal communities.Monitoring buoy data and advanced forecasting models help meteorologists provide accurate predictions.
Hawaii’s coastal communities rely on this information for timely warnings and preparedness.

Long-Term Coastal Erosion in Hawaii
Beyond immediate surf conditions, Hawaii faces ongoing challenges from coastal erosion. Rising sea levels and increased storm intensity are accelerating erosion rates, threatening infrastructure and natural habitats.
Efforts to combat coastal erosion include beach nourishment projects, seawall construction, and managed retreat strategies. However, these solutions are often costly and can have unintended consequences for marine ecosystems.
Sustainable coastal management practices are essential for protecting Hawaii’s shorelines for future generations. This includes reducing greenhouse gas emissions, implementing stricter building codes in coastal zones, and fostering community awareness of coastal hazards.
