The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the menu for the next couple of weeks.
Right off the bat, we’ve got a bit of a slow start. The first few days are pretty grim with messy, onshore winds and weak, jumbled swell. Don’t even bother waxing up until at least Tuesday the 11th, and even then it’s only just getting a pulse. The real story here is a big spike of energy that rolls in deep into the second week.
For the first standout, you’re looking at Monday the 17th of August. That’s the day. We’ve got a solid 12 ft swell from the East, with a clean offshore wind from the NE. That’s proper groundswell energy, with a combined energy of 1691, which is strong. The period is 9 seconds, so it’s not super long, but with that size and clean offshore wind, Bikini is going to be pumping. The water is sitting at 54°, which is a touch warmer than normal for this time of year. Keep in mind, this is for advanced surfers only – 12 ft is big, powerful stuff, and the break is very consistent. You’ll want to be on your game, and expect crowds as it’s often busy.
The next morning, Tuesday the 18th of August, still has size but the wind swings Westerly and gets strong. The morning shows 8 ft from the East, but with a strong cross-onshore breeze, it’s going to be messy. The afternoon is a write-off with a near gale. So that Monday morning is your golden window.
Later in the week, Saturday the 22nd of August offers a return to cleaner conditions. The swell drops to 4 ft from the ESE, but with a light cross-offshore breeze from the ENE, it’ll be tidy. The combined energy is 338, so it’s moderate. It’s a much smaller, friendlier option for a longboard or a funboard, and the offshore wind will keep it clean. The crowds are a thing there, so you’ll have company.
Overall, don’t waste your time on the first week. It’s a washout. That Monday the 17th is the absolute standout, but it’s for the pros. The Saturday after is a nice little reward for those who can wait.
Stay frothy,
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.
