1.) Less Beach Obsession by Cyjon
Sims must be outside to autonomously engage in beach activities.
2.) Autonomous ocean swimming depending on season, temperature, personality, etc by Lamare
With this mod installed both playable sims and visitors can and will autonomously swim in the ocean, provided there’s a beach and no restrictions are met. (They kinda could already, but hardly ever did.)
Sim’s decision whether to get in water or not, depends on: current season, presence of deep snow (because you don’t want snow angels in swimwear), outdoor temperature (must be at least comfortable outside or it’s no fun), body temperature, and more.
3.) “Surf’s Up!” – New surfing interaction and set by Maybesomethingdunno
Is your visit to Twikkii Island lacking something? Are your beach bums tired of building sandcastles? Do your beach goers need a means to show off their abs? (Do your beach goers need a means to actually develop those abs?) Fear not! I give you something EA should have given us when they made Bon Voyage: Surfing! This is a new, socialable self-interaction with a custom queue icon and custom animation. Surfing is available for Sims who are Teens and older (who aren’t in the “showing” stages of pregnancy) and who are not Servos. As you would expect, surfing is only available on beach lots and a Sim must have a surfboard in their inventory.
4.) Temperate Beach Activities by Maybesomethingdunno
This is a global mod that overrides the guardian BHAVs for the Swim and sunbathe interactions so that the outside temperate must be at least 5 degrees Simsius (Simahrenheit?). If the Sim’s body temperature is “hot,” they will still swim regardless of the outdoor temperature.
5.) No Autonomous Watch Waves by Squinge
The mod nukes the autonomous behavior of Sims watching the waves, but the mod does not nuke the option to watch the ocean waves.
