Umegahama Rivermouth is a popular surf spot known for its unique conditions. This spot works best during Southeast swells and can be a good choice for experienced surfers looking for some action. The beach is quite long, stretching up towards Shoojiun, providing a little room to explore and find your own peaks.

The waves here generally break over sand, with right-handers that can deliver quality rides, especially during mid to high tide. You can expect optimal conditions when the swell is coming from the Southeast, but it can also pick up swells from the East and South. The spot usually handles swell sizes around 2 feet (0.6 meters) quite well, but it's best suited for expert surfers due to the crowd and the nature of the waves.

Keep in mind that when the surf's on, you’ll likely be part of a crowd filled with skilled local surfers. If you want a change of scenery, you might consider making your way to Cape Toi. There, you can check out different reef breaks and enjoy the sights of the wild horses roaming around.
