The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cooking for the next couple of weeks at Bikini. It’s a bit of a frustrating run, to be honest, so don’t be in a rush.
We’re looking at a real slow start. The first proper chance to get wet won't be until Sunday morning, the 16th of August. Before that, we’ve got a couple of days of nothing but onshore junk and weak energy. The waiting game is on.
Sunday morning, the 16th, is our first real glimmer of hope. We’ve got a 4ft swell from the East, and the wind is a clean offshore from the North. That’s a nice combo for Bikini. The wave energy is moderate (219), and the water temp is sitting at 52°, which is about normal for this time of year. This is your best bet early on, but it’s not a massive standout.
Then things go quiet again. A lot of light rain, cross-on winds, and weak, short-period swell for the next few days. Not worth paddling out for.
The true standout, the one you need to circle on your calendar, is the morning of Tuesday the 25th of August. The wind goes glassy offshore from the Northeast, with a clean 5ft swell from the SSE. The period is a nice long 12 seconds, which means groundswell with real push. The combined energy is moderate (593). This is the best-conditioned surf in the whole window. Expect clean, lined-up waves. It’s a consistent spot, so you won’t be waiting forever, but it can get crowded here, so get there early.
The 23rd of August has some serious size—10ft on the Sunday morning—but it’s accompanied by onshore wind and a “poor” call. That’s expert-only territory, and messy with it. The 28th of August also shows a 10ft day, but again, it’s blown out with cross-on winds. At that size and with those winds, Bikini is more of a kite-surfing setup than a paddle-surfing one.
So, to wrap it up: Sunday the 16th morning is a goer for a clean, fun session. The absolute best of the lot is Tuesday the 25th morning. Everything else is either too small, too windy, or too big and messy.
Stay patient, and keep an eye on that Tuesday morning.
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.
