The Lowdown
Alright folks, Rusty here. Let's have a look at what Bikini's got cookin' for us over the next couple of weeks.
Honestly, for the first few days, it's pretty flat and ugly. We've got a real slow start. From Wednesday the 19th through Sunday the 23rd of August, the energy is just not there. The swell is tiny, the wind is mostly cross or onshore, and it's all tagged as "poor surf conditions." The combined energy is barely cracking 65 (65) at best, and it drops to a measly 20 (20) on Thursday. That's a solid five-day stretch of nothing worth paddling out for.
Then, things start to get interesting. The real standout window opens up on Monday the 24th of August. That's the one. We get a clean 6ft south-southeast groundswell rolling in with a solid 12-second period. The wind goes light offshore from the northeast – that's a game changer. The combined energy jumps to 861 (861), which is a proper push of power. This is a point-and-beach setup, and with that long period, it could be a bit straight on the beach, but the point should handle it beautifully. This is the session to circle on the calendar. Even though it's an advanced wave, the clean conditions should make it a proper standout.
The Monday afternoon stays okay, but the wind picks up a touch. Tuesday the 25th still has some clean, offshore conditions in the morning with a 3ft SSE swell, but the energy drops off a lot. By Wednesday the 26th, we're back to small, weak waves, and from Thursday the 27th onward, it's mostly onshore slop and tiny swell again, with the combined energy sitting below 100 (100) for the rest of the run.
So, to sum it up: don't bother paddling out until Monday the 24th. That morning is your best bet by a mile. Everything else is a write-off or just too ordinary to get excited about.
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.
