The Lowdown
Alright, let’s get into it. The name’s Rusty, and I’ve been watching this stretch for a while now. The coming week and a half is a bit of a mixed bag, with plenty of small, average days and a few windows that’ll get your heart rate up. You gotta pick your moments – the swell isn’t big, but when everything lines up, it’ll be worth the wait.
The standout for the whole period is Bikini itself. This is an advanced spot, very consistent and exposed to the south, so it picks up whatever comes its way. The crowd is often there, but that’s a sign of the quality. The water temp is about average for this time of year, nothing to worry about.
The first real chance to get something decent is on Monday the 3rd of August. The morning session is the pick of the early days. We’ve got a clean 3ft swell out of the south-southeast, with a period of 11 seconds – that’s proper groundswell with some push. The wind is light from the northeast, so it’s clean and glassy. The combined energy is moderate (225), so you’ll feel it. It’s not huge, but it’s the best surfable wave we’ve had in a while.
After that, things go quiet again. A few small, offshore mornings pop up on the 5th and 6th, but the swell is tiny and weak – not worth paddling out for unless you’re desperate for a longboard.
The next real standout, and the one to circle on your calendar, is Sunday the 9th of August. The morning is a gem. We’re looking at 4ft of swell out of the south-southeast, period of 10 seconds, and a glassy wind from the southwest – that’s zero wind, perfect clean conditions. The combined energy is moderate to strong (278), and for a spot like this, that’s a solid pulse. This is the best morning of the whole forecast for a surfer who knows what they’re doing. The afternoon gets a bit choppy and cross, so get in early.
Then we get a bit of a tease on Monday the 10th of August. The afternoon sees a jump in energy – that southeast swell picks up to 5ft with a period of 11 seconds, and the combined energy hits 680 (moderate to strong). The wind is cross-offshore, keeping it clean. It’s a solid, if not massive, south swell. The morning before that is smaller and cleaner but not as punchy.
Tuesday the 11th of August gets a bit gnarly. The swell is pushing 6ft out of the south-southeast with a very long 14-second period, and the energy is strong (1303). That’s a big, powerful groundswell – the kind that will have some serious heft. But the wind is cross-on or onshore, so it’s going to be a bumpy, tricky paddle. This is strictly for the experienced guys who can handle a messy, powerful wave. Not for beginners.
Wednesday the 12th of August morning is a nice rebound. The swell drops to 4ft, still from the south-southeast, period 12 seconds, and it’s glassy. The combined energy is still solid (407). That’s a clean, powerful morning with good shape.
The final week of the forecast is mostly small and onshore, with a few clean days but nothing that stands out as a session to chase. The swell is there, but the wind is a constant battle. It’s a waiting game after the 12th.
So, to sum it up: the absolute best on offer is Sunday morning the 9th of August at Bikini. Clean, glassy, and a solid 4ft south swell. The runner-up is Monday afternoon the 10th of August for a bigger, cleaner groundswell, and the Wednesday morning the 12th of August for another glassy session. Everything else? Small, marginal, or windy. You’ll have to work for it.
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.
