Small Craft Advisory Remains in Effect Across Hawaiian Waters
A Small Craft Advisory (SCA) continues for several Hawaiian coastal waters as strong trade winds, elevated seas, and swells influenced by Tropical Storm Elida create hazardous marine conditions around the islands. While Elida is expected to remain well south of Hawaii and is not forecast to make landfall, the storm is contributing to enhanced swells and rough ocean conditions that increase the risk for anyone venturing onto the water.
Marine forecasts indicate sustained winds of 20 to 25 knots, with locally higher gusts in the channels and around the Big Island. Seas generally range from 5 to 8 feet, with the roughest conditions occurring in windier channels and exposed waters.
Hilo Faces Elevated Marine Hazards
Around Hilo and the Big Island, east-facing waters remain especially hazardous due to persistent trade winds and incoming swell energy. The National Weather Service continues advisories for portions of the Big Island’s windward, leeward, and southeast waters as rough seas make navigation difficult for smaller boats.
Residents and visitors should expect:
- Choppy seas and rough surf along east-facing shorelines
- Strong currents near harbor entrances
- Difficult conditions for fishing vessels and recreational boaters
- Increased wave action capable of producing dangerous shore breaks
Honolulu Also Experiencing Hazardous Boating Conditions
Although Honolulu is not expected to experience direct tropical impacts from Elida, surrounding coastal waters remain hazardous because of strengthened trade winds and elevated seas across portions of the island chain. Nearby channels continue to experience rough conditions that can challenge even experienced mariners.
Beachgoers should also remain alert for:
- Strong rip currents
- Larger breaking waves on exposed beaches
- Dangerous swimming conditions
- Unexpected wave surges along rocky coastlines
How Tropical Storm Elida Is Influencing Hawaii
Tropical Storm Elida remains well south of the Hawaiian Islands, but its circulation is helping reinforce the regional pressure gradient that supports stronger trade winds while also sending long-period swell toward portions of the state. Even without a direct strike, tropical cyclones in the eastern Pacific can create hazardous marine conditions hundreds of miles away.
The greatest impacts are expected to remain marine-related, including:
- Rough seas
- Elevated surf
- Hazardous boating conditions
- Dangerous rip currents
- Difficult navigation in channels and exposed waters
Boating Safety Tips
Anyone planning activities on the water should:
- Monitor the latest marine forecasts before departure.
- Postpone trips in small boats until conditions improve.
- Wear a properly fitted life jacket at all times.
- Secure loose equipment and check emergency communications.
- Avoid venturing into rough channels or exposed waters during advisory conditions.
Stay Weather Aware
Although Tropical Storm Elida is forecast to remain offshore, its influence on Hawaii’s coastal waters serves as an important reminder that distant tropical systems can still create dangerous ocean conditions. Mariners, surfers, paddlers, and beach visitors should continue monitoring forecasts and heed all marine advisories until conditions improve.
