Maui firefighters rescued a group of paddle boarders who had trouble returning to shore because of strong tradewinds Thursday.

Firefighters responded to an area off Pohaku Park known as S-turns in West Maui at about 12:39 p.m., a Fire Department spokesman said in a written news release.

A resident manager at a nearby condominium called 911 after he noticed the group being blown downwind.

Firefighters arrived at 12:46 p.m. Witnesses directed the firefighters to three standup paddle boarders who appeared to be struggling against the winds about 400 yards offshore.

Lifeguards on rescue watercraft helped the paddle boarders, two males and a female, to shore by 1 p.m.

A fourth paddle boarder, a woman, made it to shore on her own.

The group, tourists from California, did not need medical attention, the Fire Department said.

Tradewinds were blowing at 15 to 20 mph at the time of the incident, the Fire Department said.

The National Weather Service says strong tradewinds, with a few showers blown in by the trades, are expected to continue until Sunday.

Forecasters extended a high-surf advisory  through 6 p.m. Sunday for east-facing shores of most Hawaii islands.

The advisory is for east-facing shores of Kauai, Oahu, Molokai, Maui and the Big Island.

Strong tradewinds have combined with an east swell to continue rough surf, the weather service said.
