Table - best surf conditions forecast for Bikini over the next 16 days.
Right, let’s have a look at what’s on offer. Over the next couple of weeks, Bikini (a beach and point setup) is gonna be a bit of a mixed bag. The first few days show some rideable waves, but nothing that’ll have you calling in sick. Real standout action is hard to come by, and after the first week, things get messy with a lot of wind and lumpy conditions. There’s a gap of about a week starting Friday the 17th of July where the surf is mostly poor, so don’t get your hopes up for a long run of good days.
The best bet looks like Tuesday morning, July 14th. We’ve got a clean 4ft swell coming from the ESE with a period of 10 seconds, and the wind is offshore from the NNE at 6 mph. That’ll give you some clean lines. The water temp is sitting at 52°, which is about average for this time of year, so nothing wild there. The combined energy is moderate at 216, so there’s some push to it. This is a solid window for an advanced surfer, but it’s not huge. The point here should hold the shape nicely with that longer period.
After that, the week of the 16th onward really drops off. Thursday afternoon the 16th sees a bit of a pulse with 3ft and an 11-second period, but the wind is already strong and the energy is modest. By Friday the 17th, it’s a write-off. Then from the 20th of July, we get a lot of cross-shore wind and chop, with swell heights occasionally hitting 6ft to 7ft, but the wind is just too strong and from the wrong directions. This setup looks more interesting for kite surfing than paddle surfing, especially on the 25th and 26th when the wind is howling and the sea state is messy.
If you’re holding out for a miracle, the 28th of July morning has a 3ft SSE swell, long period of 12 seconds, and light cross-shore wind, but it’s a marginal call. Overall, it’s a slim window for quality surf. Keep an eye on the forecast, but don’t book the week off.

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.
