Ocean swimming

Ocean swimming is a feature that enables Sims to swim in the ocean or open seas, introduced in The Sims 2: Bon Voyage and The Sims 3: Seasons. The feature is available in Patch 42 for players who do not have Seasons.

The Sims 2: Bon Voyage
Swimming in the ocean was first introduced in Bon Voyage. In Twikkii Island, some lots are right on the shoreline, and Sims are able to swim in the ocean.

List of lots that contain a beach

 * Seawater Beach Paradise (Community lot)
 * South End Beach (Community lot)
 * Twikkii Beach Boardwalk (Community lot)
 * Brickstone Chateau (Residential lot)
 * Potterhouse Bungalows (Hotel)
 * Twikki Beach Hotel (Hotel)

The Sims 3: Seasons
Sims can swim in oceans near beaches and coastal areas at any time year-round. They can also swim in any body of water (eg: lake, river) that is not in a lot, whether commercial or residential. They can swim under bridges too. It can be done on any neighborhood, including World Adventures, store and custom neighborhoods.

''Sims will be able to swim on a body of water even if it has unroutable paint laid down beneath the water. There’s a different paint type that’s used around the edges of the world to block the camera from going too far – Sims won’t be able to swim beyond that point (or wherever that paint is laid down).''

When swimming, Sims gain their Athletic skill but lose energy motive, which can cause fatigue. They cannot drown and also skinny dip. They can splash at one another, similar in a swimming pool and also relax in the ocean on a lounger.

Parts of the ocean can freeze over when the temperature drops low enough in the winter, thus Sims are not able to swim over that part until Winter is over. If lucky enough, Sims can swim on oceans during Winter and get a positive "Polar Bear Club" moodlet.

Pets cannot swim in any bodies of water.
