The Lowdown
Right off the bat, I gotta be straight with you. The next couple of weeks are looking pretty bleak for any kind of decent surf around here. We've got a long stretch of onshore wind, weak energy, and a whole lot of nothing that’ll get your heart racing. Honestly, for the first week and a half, there’s just nothing on the table. You’re better off finding a different hobby for the next ten days or so.
Looking at the whole picture, the swell energy is weak to moderate for most of the coming days. We're looking at combined energy readings in the low hundreds, which is just not enough to push any real shape through. It’s mostly short-period windswell, and with the wind state being cross-onshore or choppy for a huge chunk of that time, it’s going to be a mess out there.
There’s a small window on Sunday the 16th where the wind drops to a light breeze and we get a little cross-off action, but the swell’s barely 3ft and the period is short. It’s surfable, but calling it 'good' would be a stretch. It’s just something to get wet on.
Then we get this bigger pulse of swell arriving on the 22nd and 23rd of August. The swell heights are pushing up to 6ft and 8ft, and the energy jumps into the 400s and 600s. But here’s the catch: it’s all coming from the SW with a cross-on wind and a lot of strength behind it. The conditions are going to be rough, lumpy, and just blown out. For a spot like Bikini (Bikini), which is a beach and point set-up, this is going to be more of a battle than a pleasure. Honestly, this looks more interesting for the kite surfers than anyone on a paddleboard.
Here’s where things finally get interesting. The real standout is Thursday morning, the 27th of August. We're looking at a solid 7ft of east swell, with a light offshore wind from the NW making it clean. The energy is strong, coming in at 521, and the forecast is setting it up to be ‘very good’. This is the one to circle on the calendar. It’s the only real highlight in the whole run, but if you can get out there, it could be special.
The other one to keep an eye on is the 29th of August, Saturday morning. The swell drops a bit to 3ft, but the wind swings around to the north and becomes cross-off, and by the afternoon it goes completely glassy with a calm wind. It’s not big, but it’ll be clean. That’s the trade-off sometimes – it’s small, but you might get a fun, lined-up wave if the period holds.
Also, water temp is sitting at 52°, which is about average for this time of year. So, don’t be fooled by the sun; you’re still going to want the full suit.
Anyway, keep your head up. The 27th is looking promising, but it’s a long way out, so we’ll see if it holds. For now, maybe tune up the board and wait for that window.

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.
