The Lowdown
Alright, Rusty here. Let's take a look at what Bikini is serving up.
Water's sitting about 52°F, which is pretty standard for this time of year.
The first couple of days are a total loss for any good paddle surfing. Sunday the 23rd has a chunky 8ft south swell at 13 seconds, and the combined energy is a massive 2084 – that's some heavy, powerful water. But the wind is howling onshore from the SSW at 16 mph, just smashing it up. Conditions are poor. That's a day to stay on the sand. Monday the 24th drops to a 6ft SSE swell at 12 seconds, but it's still cross-onshore and choppy. Not worth it.
The real window opens Tuesday the 25th, and Wednesday the 26th is the absolute best of the whole forecast. On Wednesday morning, we've got clean 5ft SE swell with a 14-second period (proper groundswell), and the wind is light offshore from the NNE at 6 mph. That's going to give us clean, lined-up waves at this beach and point setup. The combined energy is 822, a solid moderate push. Wednesday afternoon stays clean with a gentle offshore. This is the day to circle. Tuesday morning is also clean with 4ft swell and offshore wind, but Wednesday has the extra period and the better score.
Thursday the 27th morning is glassy – zero wind – with a smaller 3ft SE swell at 12 seconds. It'll be clean and fun on a log, but the energy fades fast in the afternoon as the wind turns onshore.
From Friday the 28th right through to early September, it's mostly flat or weak. Swell heights drop below 3ft, periods get short, or the wind is wrong. There's a little bump on the 31st of August with a 3ft east swell, but the period is only 8 seconds and the conditions are just ordinary. The combined energy readings are mostly in the double or low triple digits, meaning weak to weak-moderate energy. It's a long, quiet stretch.
There's a small sign of life on the 7th of September with a 3ft south swell at 11 seconds and 238 energy, but the wind is cross-onshore again. Too far out to bank on.
Bottom line: if you're a surfer, aim for Wednesday the 26th and maybe the morning of the 27th. The rest of this 16-day run looks pretty grim for any decent paddle surfing.
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.
