The Lowdown
Alright folks, Rusty here. Let’s get into it.
We’re looking at a pretty quiet start for Bikini. The first few days are a write-off with tiny, weak swell and mostly onshore or messy winds. It’s not until the first of August, Saturday morning, that we see something surfable, but it’s a bit marginal. The swell is coming from the east at 4ft with a 10-second period, and the combined energy is moderate (235). The wind is light and cross-shore, so it’ll be a bit bumpy but rideable. Not a standout.
Sunday the 2nd and Monday the 3rd are small and ordinary, with swell under 3ft. The energy is weak (23 to 173). The water temperature is about average for the time of year, nothing unusual.
The real action starts to look interesting around Monday the 10th of August. The morning brings a 6ft south-southeast swell with a 10-second period and strong energy (530). That’s a solid pulse, but it’s a bit crossed up with the wind, so it’s not perfect. The afternoon cleans up nicely with 5ft and a moderate offshore breeze, making for a cleaner session. This is the best on offer in the first week.
Thursday the 13th of August morning is a proper standout. We’ve got a 5ft easterly swell with a 9-second period, light offshore winds, and clean conditions. The energy is strong (311). This is the pick of the entire outlook. Bikini’s a beach and point setup, so it’ll handle that east swell well. Crowds are often a factor here, so expect company.
Friday the 14th also delivers. Morning has a 5ft south-southwest swell with a short 6-second period, but the wind is light and cross-offshore, and the energy is strong (271). The afternoon is even better with a gentle offshore breeze and clean waves. Another solid option.
That’s about it. The rest of the 16 days fades back into small, weak, or onshore slop. The gap between the 10th and the 13th is only a couple of days, but nothing else in the second week comes close to that Thursday morning.
Stay stoked, and keep an eye on that 13th.

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.
