Hawaii Five-0 will take to the sea for the season 5 premiere.

'Hawaii Five-0' Scott Caan Welcomes Baby Girl, Filming Begins For Season 5

The series wrapped filming for "Nu'a Nalu" on July 17, but new pictures show the CBS drama taking advantage of the sun and surf on July 14.

Photos from H50hana show a bikini-clad Grace Park (Kono) and a stunt team head out into open water on a small boat while two other crewmembers follow along on jet skies. When the actress returned to land, she stepped under a shower to either rinse off the salt water or keep herself looking damp as filming continued (see photo here).

Will McGarrett Solve The Shelburne Mystery Soon On 'Hawaii Five-0'?

Park appeared to be the only main cast member on hand, although a possible stunt double for Scott Caan's Danny Williams was also spotted carrying a surf board up from the water (see photo here).

Premiere plot details remain scarce, but Hawaii Five-0 and Steve McGarrett's (Alex O'Loughlin) team will probably be preoccupied with Wo Fat's (Mark Dacascos) reappearance when the series returns. The long-running villain resurfaced at the end of the season 4 finale, and he will undoubtedly have a major role to play in early episodes.
