Alright, folks, Rusty here. Let’s have a look at what’s coming down the line for Bikini. Gotta be straight with you – this is a tough outlook. We’ve got a long stretch of poor conditions ahead, so let's break it down.

The pattern is decidedly bleak for the first week and a half. The wind is mostly onshore or cross-shore, and the swell is weak and short-period. The only real glimmer in the first few days comes on Sunday, July 5. The morning is dead calm with glassy conditions and a clean 3ft swell from the ESE. The afternoon stays glassy with a light NE wind. It’s small, but for a few hours it’ll be the cleanest surf you’ll see for a while. For a break that is very consistent and exposed to the S, this is a rare moment of peace.

Then, get ready for a long dry spell. From Monday the 6th all the way through to Wednesday the 15th, the recommendation scores are non-existent. We’re talking wind-affected, lumpy, and messy surf with mostly onshore flow. There's a pulse of bigger energy around the 13th with a 8ft swell, but it’s being hammered by a 22 mph cross-onshore wind – total washout. That’s over a week of poor conditions.

The one standout that catches my eye is Thursday, July 16. Now, this is far out, so keep your expectations in check, but the potential is huge. A very long-period groundswell of 15 seconds out of the SSE hits 8ft. The combined energy is massive at (2315). This is serious, heavy water – strictly for advanced surfers only. The catch? Wind is a direct onshore 22 mph, so the surface will be trash. This is a raw power session for experts who don’t mind a battle. It’s not for the faint of heart or anyone on a foamie.

Friday the 17th sees the swell dropping to 4ft with a still-strong period of 14 seconds (563 combined energy), but the wind is light and cross-onshore, making for marginal but rideable waves. The water temp is 53°, about average for the time of year.

Honestly, if you’re a kite surfer, you might get more out of the bigger wind days, especially the 13th and 16th. For paddle surfing, the only true clean windows are the glassy Sunday morning on July 5 and maybe a cautious look at the big, wind-blown swell on the 16th if you’re an expert. The rest is a write-off. It tends not to stay this poor forever, but right now, it’s a long wait.

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.
