The Lowdown
Alright, listen up, it's Rusty. Let's talk about Bikini. The water's a touch warmer than normal for this time of year, at 55°F, so that's a small win.
The first week is a real bone-yard, to be honest. We see a little flicker of hope on Monday the 3rd of August. The swell is tiny, only 3ft from the SSE, but the wind goes glassy in the afternoon. The combined energy is moderate at 162, and it's clean, with a long period of 11 seconds from a groundswell. It's not going to be world-class, but it's the first half-decent paddle you'll get. The next morning, Tuesday the 4th, has a similar size but the wind is onshore and messy, so it's a waste.
Wednesday the 5th and Thursday the 6th are small and clean again, but the swell is weak. Thursday afternoon sees a jump to 6ft from the SW, but the wind is cross-shore and the combined energy climbs to 254. It's still marginal, not a standout.
The real deal, and I mean the only proper standout in this whole 16-day window, hits on Monday the 10th of August. We've got an 8ft swell from the south with a very long period of 16 seconds. The combined energy is huge at 3430. The wind is offshore from the NW, so it'll be clean. But here's the catch – this is a massive, powerful, very long-period groundswell. At over 8ft, this is for experts only. And with that long period, it's going to be a bit too straight and close out at the beach. The point break at Bikini (Bikini) will be the only spot to handle it, and even then, it'll be a washing machine. The morning of the 10th is the absolute best on offer, but it's a heavy, dangerous wave. The afternoon drops to 7ft, still big, but the wind turns cross-offshore.
The rest of the forecast is a total loss. Tuesday the 11th is blown out by fresh onshore winds. The following days are a mix of small, weak swell and onshore or cross-offshore winds with poor conditions. The second week is a write-off, with a huge gap in quality. By the 16th of August, we're looking at 7ft from the ESE, but with a near gale-force cross-onshore wind, it's a complete disaster.
So, to sum it up: the first week is a very slow, small grind. The only real, dangerous standout is the morning of the 10th for the experts. Stay safe out there.
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.
