The Lowdown
Righto, Rusty here. Lookin' at the charts for Bikini (beach and point) and gotta be straight with ya – it's a bit of a mixed bag for the next couple of weeks. The first week is gonna be a real struggle to find something worthwhile. We're lookin' at a run of mushy, average conditions with a constant cross or cross-off wind messin' with the face. The swell's around, but the quality just ain't there for the most part.
Let's start with Tuesday the 11th and Wednesday the 12th. We've got 5ft to 6ft of SSE groundswell with a decent 11 to 13-second period, but the wind's blowin' cross-shore from the SE, puttin' a chop on it. The energy is moderate – around 488 to 768 on the dial – but the conditions are just "marginal". It's surfable, but you'll be workin' for it.
Thursday the 13th and Friday the 14th are no better. The swell drops a touch, but then Friday afternoon we get a horrible 6ft blast of short-period E swell at just 6 seconds with 19 mph cross-off winds. That's a total write-off. The energy's moderate (416), but the period is too short and the wind's too strong. It's a mess.
Saturday the 15th sees the swell drop under 4ft, still short period from the E. Still nothin' to get excited about.
Now, here's the one and only standout in the first week. Sunday morning, August 16th. We finally get a bit of a window. The swell is a modest 4ft from the E with an 8-second period, but the magic is in the wind – a light offshore from the NE at 6 mph. That's clean, glassy conditions. The energy is light (203), but for a paddlin' session, those smooth faces will make it feel way better than the numbers suggest. It's the best on offer by a long shot. Keep in mind, this spot can get crowded, so get in early.
The rest of that day and into Monday the 17th is a write-off with onshore winds. We then hit a serious dry spell. From Monday afternoon all the way through to Saturday the 23rd, the swell drops off hard. We're talkin' ankle-to-knee high dribble for almost a full week. The wind is all over the shop – cross-on, onshore, choppy. Nothin' doin'.
Then, hold onto your boardies. Monday the 24th of August. A big, long-period SSE groundswell rolls in at 6ft with a 14-second period. The energy is strong – 1470! This is expert territory with that size. The problem is the wind: a moderate cross-onshore from the SE at 12 mph, puttin' a chop on it. It's a powerful, raw swell, but the onshore breeze will mess with the shape. For the experienced lads, this could offer some heavy, lumpy barrels, but it won't be clean.
Tuesday the 25th hangs in there with 6ft S swell and 12-second period, but the wind picks up to 19 mph from the E, making for a clean but very windy and bumpy day. By Wednesday, it's all over.
So, lookin' at the whole 16 days, the only true standout is that Sunday morning, August 16th. The big swell on the 24th is for the brave and the patient, but it's a long way out.
Stay salty,
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.
