The Lowdown
Alright, folks, Rusty here with the skinny on the Bikini area. It’s a bit of a rollercoaster, so let’s break it down.
The first day is a total washout. Friday the 7th has a solid 10ft swell from the SSW, but it’s getting hammered by a 25 mph cross-onshore wind. The energy is massive, but it’s just a messy, blown-out mess. That’s for experts only, and even then, it’s not pretty. The water is at 54°, which is a touch warmer than usual for this time of year, so that’s a small win.
We’ve got a few days of nothing. Saturday the 8th and Sunday the 9th are all blown out by strong winds, with messy, short-period swell. The surf is just junk. Monday the 10th is a bit cleaner with the wind, but the swell is still onshore and weak. The energy drops, so it’s not worth the paddle.
Things start to look a little more promising around Tuesday the 11th. The swell drops to 6ft from the SSE, with a period of 12 seconds. That’s a nice, long groundswell. The wind is light from the SE, but it’s still cross-onshore, so it’s not perfect. The energy is moderate. This is a marginal one, but it could be a fun session if you’re not too picky. The same goes for Wednesday the 12th and Thursday the 13th, with similar conditions and a bit of a drop in swell.
Now, the standout in the first week is Friday the 14th. The morning is looking glassy. The wind is a light 3 mph from the S, and the swell is 4ft from the SSE with a 12-second period. That’s clean, glassy, and the energy is solid. This is the one to circle. The break is a beach and point setup, which is very consistent, and it’s exposed to the S swell. The crowd profile is “often” so expect some company, but for that clean, glassy morning, it’s worth it. The best of the week.
From Saturday the 15th, we hit a real dry spell. The swell drops to 2ft, and then it’s all cross-onshore or cross-off winds with tiny, weak waves. The energy is down in the double digits. There’s a gap of about 4 days where there’s just nothing to write home about.
We get a bit of a pulse on Monday the 17th, but the wind is howling from the E at 22 mph, making it a mess. Tuesday the 18th is the same story. The energy is strong, but it’s all cross-onshore and lumpy. Not a good look.
The second week’s best bet is a long-range call. Wednesday the 19th has a 5ft swell from the E with a 12-second period, but the wind is onshore from the SSW. It’s marginal. The real promise is on Thursday the 20th. The morning is glassy again, with a 3ft swell from the E and an 11-second period. The energy is moderate. That’s clean and small, but with light winds. It’s a promising but less certain call for the second week. The same goes for Friday the 21st, with a clean cross-off wind and a 4ft swell from the S.
That’s the run. The first week is a write-off except for that glassy Friday morning, and the second week has a couple of small, clean windows. It’s not a classic run, but that Friday the 14th is a beauty.

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.
