Since swimming and diving was something that could be done in Animal Crossing: New Leaf, we've long suspected that these aquatic activities would be coming to New Horizons. Finally, three months after the game's release, players will be able to jump into the big blue and take part in several new oceanic activities.

Whether you're trading scallops with Pascal for Mermiad DIY recipes or looking for new creatures to take to Blather's museum, there are plenty of fun new experiences to discover. Here's how to unlock swimming in Animal Crossing: New Horizons along with a list of all the water activities that come with it.

How to download the Summer Update Wave 1

If, for some reason, the new swimming festivities don't seem to have appeared in your game come July 3, then maybe you need to make sure your Switch downloaded the Summer update.

  1. From the Nintendo Switch's Home menu, hover over the Animal Crossing: New Horizons icon.
  2. Press + and the game information will display.
  3. Scroll down to Software Update.
  4. Select Via the Internet. The Switch will check for any new versions and will download them if necessary.
  5. Select OK.

Once these steps have been taken, your Switch will search for any Animal Crossing: New Horizons updates it might not have already. Hopefully that solves the issue and allows you to take part in the summer festivities.

How to unlock swimming & diving

In order to go swimming, players can either acquire a wet suit from the Nook Miles Kiosk or from the cabinet at Nook's Cranny.

How to Swim & Dive

  1. Equip the wet suit.
  2. Run up to the ocean and Press A to jump in. Note that you cannot go swimming in ponds or rivers.
  3. Press A repeatedly to swim forward.
  4. Rising bubbles indicate the presence of a sea creature. Hold down the Y button when you're above bubbles to dive.
  5. Now move the joystick until you touch the creature. You'll automatically surface once you've acquired the creature or you've run out of air.

How to get a wet suit

Here are all of the recipes we know of so far:

In addition to the other watery festivities, players can randomly encounter Captain Gullivarr (pirate Gulliver), washed ashore on their beaches. After waking him, he'll ask you to gather his communicator, only this time, it will be at the bottom of the sea. Unlike sea creatures, the communicator won't move around under water. The rewards for helping him are special pirate-themed decor or clothing. It should be noted that regular Gulliver will also continue to show up, but he won't give out any pirate goods.

To see what these pirate-themed rewards look like, go here. Now, here's a list of all the rewards we've discovered so far:

Pirate Clothes

  • Pirate Bandana
  • Pirate Hat
  • Pirate Treasure Crown
  • Pirate Eyepatch
  • Pirate Beard
  • Pirate Treasure Robe
  • Pirate Dress
  • Pirate Outfit
  • Pirate Coat

  • Pirate Boots
  • Pirate Clothes

Pirate Decor

  • Pirate Cannon
  • Treasure Chest
  • Horizontal Barrel
  • Pirate Wheel
  • Pirate Barrel
  • Pirate Rug

  • Pirate Flooring

Dive in!

That's all there is to know about the Summer Update Wave 1. There are plenty of new creatures to collect, a new character to interact with, and plenty of new ways to have fun with your friends. Have fun diving into the depths around your island. I hope you can find all of the creatures you're looking for to fill out Blathers' museum.
