The Lowdown

Right, grab a coffee, mate. Rusty here. Let’s have a look at Bikini. We’re in for a real mixed bag over the next couple of weeks. The first week is a bit of a struggle, to be honest, with mostly small, messy waves, but there’s a light at the end of the tunnel. The real standout looks like it’s going to be a solid pulse of groundswell around the second week.

The water’s sitting at 54°, which is a touch warmer than normal for this time of year – nothing crazy, just a nice little anomaly.

So, for the first week, starting Thursday the 30th of July, it’s pretty ordinary. Thursday morning you’ll find some clean 1 ft surf from the SSE, but the combined energy is only moderate (102) and it’s really just surfable, not special. The wind is cross-offshore, so it’s clean, but the waves are tiny. After that, we get a long run of poor surf through Friday, Saturday, Sunday, and into Monday. The swell is either too small, too short-period, or the wind is messing it up. Monday morning the 3rd of August offers a brief glimmer with 3 ft SSE swell and a light offshore wind, giving a moderate energy reading (227), but the afternoon turns onshore again. Tuesday and Wednesday the 4th and 5th are also pretty flat and messy.

Now, Thursday the 6th of August, we see a jump in size with 7 ft waves from the south, but the period is a short 6 seconds and the wind is a strong onshore, so it’s just a messy, blown-out 7 ft wall. Not for paddling. That setup looks more interesting for kite surfing than paddle surfing.

The real deal starts to show up on Monday the 10th of August. We get a 5 ft SSE swell with a long 13-second period, and the combined energy jumps to a strong 710. The wind is cross-shore, so it’s a bit lumpy, but the power is there. It’s described as marginal, but it’s a sign of things to come.

Then, Tuesday the 11th of August, is the first true standout. We’re looking at 7 ft of S swell at 11 seconds, a very strong energy reading of 978, and mate, the wind is glassy. That’s the word. Glassy. Absolutely perfect conditions for the experienced surfers this one is aimed at. The swell is over 5 ft, so it’s a bit much for beginners, but for the crew that knows what they’re doing, this is a serious session.

The best of the best, though, is Wednesday the 12th of August. Morning surf is 6 ft from the SSE with a 13-second period, massive energy at 1212, and a light offshore wind. Clean, powerful, and long-period groundswell. This is an excellent window for experienced surfers. The afternoon switches to a cross-shore, so get it early.

The rest of the second week, from the 13th and 14th, the swell starts to drop back down, but it stays clean with some cross-shore wind. The size is 4 ft and then 3 ft, so it’s not the same grade, but it’s a nicer end to the run than the first week.

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.
