The Lowdown
Alright, folks, Rusty here. Let's have a look at what Bikini’s got cooking for us over the next couple of weeks.
Right off the bat, the first few days are pretty grim. We’ve got a bit of swell on Thursday the 6th, but it’s tiny at 1 ft from the SE with a weak period of 8 seconds and a combined energy of just 25 – barely a ripple. The wind is a messy cross-offshore, but it’s not enough to save it. The water is sitting at 55°, which is a touch warmer than normal for this time of year, but you won't be in the water long with nothing to ride.
Friday the 7th is a write-off. A big 10 ft SSW swell shows up, but it’s accompanied by a screaming 25 mph SW wind, making it an absolute washing machine. That’s a combined energy of 1585, which is powerful, but the conditions are just horrible. This one is for experts only, and even then, it’s ugly.
We limp through the weekend and into early next week with poor surf. Saturday the 8th morning has a clean 4 ft SSE groundswell (11-second period) with a moderate energy of 401, but the wind is a cross-offshore so it's rideable, but nothing to get excited about. Sunday and Monday are all cross-onshore chop and mush.
Now, here’s where it gets interesting. Tuesday the 11th and Wednesday the 12th are still marginal, but the signs are there. The real standout, the one you want to circle on your calendar, is Friday the 14th of August. The morning session is going to be firing. We’re looking at a solid 6 ft SSE groundswell with a long 13-second period. That’s a strong energy reading of 1066, meaning plenty of punch. The wind is a clean, glassy cross-offshore from the ENE at just 9 mph. For an exposed spot like Bikini that loves swell from the south, this is prime. The conditions are described as excellent for experienced surfers. The afternoon backs off a bit to 5 ft, but still clean. This is the pick of the forecast.
After that, things taper off again. Saturday the 15th and Sunday the 16th drop down to under 3 ft, and the following week looks small and weak with mostly onshore or variable winds. There’s a small blip on Monday the 17th afternoon with a 6 ft easterly, but the wind is straight onshore, making it messy.
To be honest, for a spot like Bikini, this is a pretty typical run. It’s either going to be flat or blown out, but when that Friday morning lines up, it will be worth the wait. Keep your eye on the 14th.
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.
