Alright, let's break down the surf at Bikini. It's been a slow start, no lie. From Saturday the 4th all the way through to Thursday the 10th, it's mostly flat and choppy. That's a solid week of nothing worth getting wet for.
We finally get a little something on Sunday morning the 5th. Small waves, maybe 3ft from the ESE, but the wind goes totally glassy. That's a beautiful thing—clean, smooth water, even if the swell is weak. It's a reset button after the flat spell.
The first proper session to circle comes on Saturday the 11th. We're looking at a chest-high 4ft swell from the SSE with a short 8-second period, but the wind is offshore, glassy from the NNE. That'll be lined up and clean for the more experienced guys. Water temp is about 53°, pretty normal for this time of year.
Now the big one: Friday the 17th. This is where it gets serious. A solid 13ft swell from the S, with a long 12-second period. That's heavy, groundswell energy, and the combined energy reading is a massive 4037—that's a ton of power. Wind is blowing offshore at 19 mph from the E, keeping it clean. This is expert-only territory. The point at Bikini should handle that long-period swell beautifully, but the beach breaks might get a bit straight. This is the standout of the whole forecast, though keep in mind it's over a week away, so it's a promising call, not a guarantee.
Then the run continues. Saturday the 18th still has 8ft swell, and Sunday the 19th looks excellent for experienced surfers with 7ft from the SE and a clean offshore breeze. Crowds are "often" here, so expect plenty of company for these good waves.
So, a slow first week, but the second week absolutely makes up for it. Friday the 17th and Sunday the 19th are your best bets for serious, powerful surf.

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.
