The Lowdown
Alright folks, it’s Rusty here. Let’s be straight with each other: this 16-day window for Bikini is one of the most frustrating I’ve seen in a while. We’ve got a massive gap of near-total flatness at the start, then a tease of proper swell that the wind absolutely butchers. You’ll have to be patient if you want a wave, and even then, the pickings are slim.
The first real action doesn’t show up until Sunday, September 6th. Before that, from now through Saturday the 5th, it’s a long stretch of tiny, weak, and messy conditions. There’s barely any energy and the winds are all wrong, making for poor surf. You’re honestly better off doing something else.
Now, that Sunday, September 6th is our one true standout. Overnight, the ocean wakes up proper. We’re talking a solid 6ft to 6ft swell pumping in from the SSE, with a very long period of 13 to 14 seconds. That’s real groundswell energy – you can feel the weight in it. The combined swell energy is an impressive 1204 to 1211, which is strong power. The best part? The wind goes light and cross-offshore, promising clean, organized lines. For a spot like Bikini (the break), which is a beach and point, that long-period SSE swell will hold up nicely on the point. The water temp is currently sitting at 51°F, about average for this time of year, so don’t forget a solid hood and gloves. The wave comment calls it excellent conditions for experienced surfers, and that’s because the size is over 5ft, so it’s a step up for the average punter – this is for the crew who can handle a proper point break session. Crowds are often an issue here, so get on it early for the pick of the sets.
Anything before that Sunday is a write-off. Anything after, like Monday the 7th, is a cruel joke: the swell sticks around at 5ft to 6ft, but the wind swings onshore and howls at 18-22 mph, turning it into a lumpy, cross-on mess. The rest of the second week offers nothing but small, weak surf with crummy winds. Not worth the paddle.
So mark your calendar for Sunday, September 6th. That’s your one shot at something special. The rest is a waiting game.
Rusty.

Information about the Bikini Surf forecast
The above surf forecast table for Bikini provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Bikini can be found by selecting the local surf guide option on the grey menu. Our Bikini surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Bikini) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Bikini may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
Bikini is 17 km (11 miles) from the city of San Carlos. If you plan a holiday in Uruguay - South, look for hotels and other accommodation in San Carlos. San Carlos has rooms for a wide range of budgets as well as car hire and transport links.
