The Lowdown
Alright folks, Rusty here. Let’s get into it for this patch of ocean around Bikini. The long and short of it is, we’re staring down a pretty grim 16-day window. There’s basically no good surf to get excited about. The first 14 days are all marked as poor surf conditions, with scores that don’t inspire any hope. We’ve got a blank run from the start all the way through to the morning of Tuesday, 11th August, so that’s a solid two-week gap where you’re better off doing something else. The only flicker of something surfable shows up on the 11th, but even then, it’s marginal and questionable.
For the first break, and the only one worth a real mention, is Bikini (beach and point). Water temp is sitting at 54°F with an anomaly of 3°F warmer than normal, so it’s a touch warmer than usual for this time of year. Comfortable enough, but that’s where the good news ends.
The only time the wave energy really gets pumping is around Friday, 7th August, but it’s a mess. That afternoon we’re looking at a 8ft swell from the WSW with a period of 7 seconds, and combined energy of all swells hitting 593 (strong energy). But the wind is a strong cross-shore at 25 mph, creating lumpy cross-chop. That’s big, ugly, and blown out. For a beach and point setup, that’s more of a kite-surfing situation than anything you’d want to paddle into. Over 8ft? Almost there, so that’s expert-only territory, and with that wind, even they’d be struggling.
The only slight glimmer is on Tuesday, 11th August, in the morning. We’ve got a 4ft swell from the south, with a long 11-second period, and combined energy of 393 (moderate). Wind is from the NNW at 9 mph, giving us a clean cross-off breeze. That’s the one window where the surf might be rideable, but even then, the forecast is only marginal. The long period on a south swell at a point break could give some nice lines, but the consistency is likely to be patchy, and it’s not a standout.
Honestly, this whole stretch is a dud. The conditions are consistently poor, and the wind is all over the shop. The only bright spot is that clean window on the 11th, but don’t hold your breath. It’s a quiet spell, and sometimes that’s just how it goes around here. Forecasts can change, but for now, I’d leave the board in the car.
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.
