The Lowdown
Alright, let’s get into it. The outlook for Bikini (Bikini) is a bit of a slow burn over the next two weeks. The first week is mostly a write-off for any decent surf, but there’s a light at the end of the tunnel with a couple of promising sessions in the second week.
Right now, the water temp is sitting at 51°F, which is about average for the time of year, so nothing crazy there.
For the first few days, from Wednesday the 15th through to the weekend, we’re looking at small, weak swell. Heights are hanging around 2ft to 3ft from the east, with a short, weak period. The combined energy is low, ranging from 73 to 120, so it’s pretty limp. The wind is blowing offshore from the NNE, which is clean, but the swell just isn’t there to get excited about. It’s surfable, but very ordinary. Thursday afternoon sees a slight bump in period to 11 seconds, but the swell height is still tiny, and the energy only hits 116. Not a standout.
Friday the 17th gets worse with a risk of thunderstorms and cross-off winds, making the conditions poor. The weekend continues in the same vein, with onshore winds and messy, weak waves. By Monday the 20th, the swell height picks up to 5ft from the SE, but the period is a poor 5 seconds, and the wind is a fresh cross-shore, creating lumpy, choppy conditions. Not worth paddling out for.
Tuesday the 21st sees the biggest swell of the period so far, 6ft from the SSE, but it’s a messy, wind-affected mess with a fresh cross-onshore breeze. The combined energy jumps to 568, but the quality is poor. That’s a big, ugly wave for experts only, and honestly, with that wind, it might be more interesting for a kite surfer than a paddle surfer.
Now, here’s where it gets interesting. The real standout comes on Sunday the 26th of July. The morning session at Bikini is looking clean with a gentle offshore breeze from the NE. Swell is 4ft from the south with a very long period of 12 seconds, giving it real groundswell power. The combined energy is a solid 473. This is the best on offer – clean, powerful, and well-shaped. Keep in mind that long period south swell like this can be a bit straight at the beach, but Bikini’s point setup should handle it nicely. Crowds are often here, so expect company.
Then Monday the 27th is another gem. The morning is light offshore from the NNE with 3ft south swell, and the afternoon goes glassy with a 4ft SSE swell and a very long period of 13 seconds. The combined energy hits 418, and glassy conditions are a major positive. That afternoon session is the absolute pick of the whole forecast.
After that, the swell drops off again through the end of the month, with smaller, less consistent waves and onshore winds returning by Wednesday the 29th.
So, to sum it up: the first week is a total blank. The second week delivers a couple of really good days. The standout is Sunday the 26th and Monday the 27th, with Monday afternoon being the real winner – clean, glassy, and powerful. Just be ready for a crowd.

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.
