The Lowdown

Alright, surfers, Rusty here. Let's get into it. It's been a quiet start, but this forecast for Bikini has some serious promise if you're willing to wait.

The next couple of weeks start off pretty disappointing. We’ve got a long stretch of nothing special from the 19th of July right through to the 24th. The swell is tiny and the wind is mostly cross or onshore, just making a mess of things. Don't even bother paddling out on the 19th or 20th – it’s just poor. We finally get a bit of a look-in on the morning of Thursday the 23rd with some clean, tiny 2ft waves from the ESE, but it’s barely surfable. The 24th is similar, with a little 1ft to 2ft south swell poking through, but it’s weak.

Then, from the 25th to the 28th, it’s a whole lot of nothing. The swell energy is there, but the wind is mostly cross-shore, keeping things messy. The afternoon of the 28th of July is a brief tease with glassy conditions on a tiny 2ft wave, but it's still just ordinary.

Now, here’s where it gets interesting. The end of the month and start of August is where the real swell shows up. Wednesday the 29th sees a pulse of 6ft to 6ft south swell, but the wind swings to the southwest, making it a choppy mess. Not worth it.

The standout window starts on the 30th of July. Thursday morning we get clean, offshore winds from the NE with a solid 5ft SSW swell. The energy is strong, and the conditions are finally clean. This is a proper session.

But the real highlight is Friday the 31st of July. That morning, Bikini is going to be pumping. We’re looking at a clean 5ft swell from the south with a very long period of 14 seconds. The wind is a light offshore breeze, and the combined energy is massive. This is groundswell, lads. It’s got power and shape. The period is over 15 seconds, so it’s a very long period groundswell, which is perfect for a point break setup like Bikini. It’s going to be clean, powerful, and well-shaped. The crowd factor is "often" here, so expect some company, but it’s worth it for this quality. This is a session for experienced surfers, as the size and power are for the crew who know what they’re doing.

The good energy rolls into the first of August with a similar 6ft SSE swell, and then Sunday the 2nd brings a big 8ft pulse from the ESE. That’s a big wave – definitely for experts only. The morning of the 2nd looks clean with a light breeze, but at 8ft, it’s a serious paddle. The 3rd of August pushes it even bigger with a 10ft SE swell, but that’s getting into the territory where it might be more interesting for the kite surfers than us paddle guys, as the cross-offshore wind will be strong.

So, to wrap it up: the first week is a write-off. The standout is absolutely Friday morning, the 31st of July. Get on 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.
