The Lowdown
Alright, Rusty here, and I’ll break it down in feet and Fahrenheit for you. The forecast is a bit of a mixed bag, but there are a couple of sessions that’ll make it all worth it.
We start off with a bit of a wait. The first few days are a write-off with strong winds and messy surf. The best bet is to sit tight until the guts of the second week.
The standout session is definitely the morning of Thursday, the 20th of August. We’ve got a solid 7ft groundswell from the ESE, and with a long period of 12 seconds, it’s packing some serious energy (1247). The wind is light and offshore out of the north, so it’s going to be clean and lined up. This is a proper groundswell, so the point at Bikini will be the spot to be, handling that long-period energy best. The water is a touch warmer than normal for this time of year, sitting at 54°F, so you might not need the thickest wetsuit.
The afternoon of the 20th will still be excellent, with 7ft of the same clean swell and light offshore winds. It’s going to be a great day.
Before that, the morning of Tuesday, the 11th of August, offers a little window. It’s a smaller 6ft SSE swell with a 12-second period, but the wind is light and variable, keeping it reasonably clean. The wave energy is moderate (793). It’s not the big day, but it’s a chance to get wet without getting blown off the water.
From the 21st onwards, things get messy again with onshore winds and smaller, weaker swells. The 18th and 19th see some big, powerful swell (over 8ft and up to 1626 energy), but with strong cross-onshore winds, it’s going to be a choppy, blown-out mess. That’s kite-surfing weather, not for a paddle board.
Later in the month, the morning of the 19th of August sees a massive 8ft swell from the ESE with a solid 11-second period and very strong energy (1568), but the wind is still cross-onshore, ruining it. It’s a frustrating one.
So, if you’re keen, save your energy for the 20th. That’s the one.

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.
