The Five Best Forecasts For International Surf Day 2026

International Surf Day (ISD) drops this Saturday, 20th June. First started in 2005 by Surfrider, there are more than 100 events taking place worldwide to raise awareness and support for our world’s beaches and coastal environments.

You can take your pick from contests, eco-friendly events, barbecues, film screenings, beach cleanups, and multiple ocean-based activities. The main goal for the day, however, is to get people surfing. But where are the best waves in the world to go surfing this ISD?

We scoured our 7000 spots, using our patented Wave Finder tool to find the ideal conditions to go surfing this Saturday. The Wave Finder is the map located below our swell, wind and energy table.

The black arrows show the wind speed and angle, while the blue icons give the swell size and direction. You can zoom in to focus on a few miles of any coastline, or zoom out to cover whole continents.

The slider bar at the bottom of the map shows how surf conditions change over time. Our premium members get to look 16 days ahead. When a surf spot’s forecast looks good, it is given a star rating out of 10. This flags the best waves or conditions on the stretch you’re looking at.

It’s a powerful tool that takes out much of the guesswork, no matter where you are in the world. We’ve also recently added a written forecast summary for the next 16 days, which highlights when the best conditions will be for individual spots or stretches of coast. Between the Wave Finder and our detailed surf forecast reports, we have handed you the keys to the ultimate surf data supercomputer. Here’s our best picks for ISD, but what are yours?

St Leu, Reunion Island

The day before ISD looks epic, with a beautiful 1.9m, SSW swell in the morning and a beefier 2.2m in the afternoon, with long periods of 14 and 16 seconds. The wind will be practically non-existent, slight air in the morning and just a whisper in the afternoon. The swell sticks around for ISD, with 2.2m from the SSW with a 14-second period; however, there’s some more wind around. We advise maybe getting in early to make the most of the cleaner conditions. Another swell kicks in Sunday, so it looks like one of the world’s premier lefts will be cooking for a while.

Lakey Peak, Sumbawa

Indonesia’s best A-Frame is looking good for the weekend. Saturday morning offers a long 18-second swell period on 0.7m of SW swell with offshore SE winds. Not huge, but still offering super fun waves. Things build slightly through the day and into Sunday with swell heights of around 1.3m and periods of 15-16 seconds, with the swell coming from the SW. Looks like good, consistent surf, though, as always at Lakey, get in early before the trades blow onshore.

Punta de Lobos, Chile

Chile looks to be copping the most swell of anywhere on the planet. Our Wave Finder shows the country’s premier left at Punta de Lobos receiving a 2.2m of SW swell with a powerful, long 19-second period in the afternoon. The combined energy jumps to a massive 3776, though the moderate breeze from the SSW at 20 km/h will affect surface conditions. That won’t stop Chile’s big wave chargers from having a crack on ISD.

Cox Bay, Vancouver Island

ISD is the absolute standout day for Vancouver Island’s premier beachbreak. The morning brings a 2.1m WNW swell with a 9-second period, an energy rating of 750 kJ, and a gentle breeze from the SSE at 15 km/h, which is cross-offshore and should offer clean waves. The afternoon gets even better, with a 2.2m WNW swell and a glassy, light southerly breeze at 5 km/h. With water temperatures a balmy 14 degrees C, and 16 hours of daylight, the BC faithful will be all over it.

Llandudno, Cape Town

Cape Town is looking bright and not so breezy, with the Saturday morning kicking off with a 1.3m SW swell, 12-second period, and 676 energy. Light NE winds should make it glassy and help the wedge barrel in the corner. In the afternoon, the energy dips a little, and the wind swings more onshore. We advise making the most of the morning offshores. The water temp is a balmy 14 degrees Celsius, the air temp 17, in what should be a bright, crisp winter’s day in South Africa.
