The Lowdown
Alright, Rusty here again, giving you the same picture in feet and miles per hour.
This is a real mixed bag for Bikini. The first few days are rideable, but nothing to shout about. Friday morning the 17th you’ve got small 2-3ft E swell with a short period, but the wind is a moderate 16 mph from the N keeping it clean. The energy is weak. It’s surfable, but very ordinary. The water temp is 52°F, about average for the season.
The standout is Saturday morning, the 18th of July. The wind goes glassy, just 3 mph from the NNE. The swell is still small at 2-3ft from the E, but the period bumps up to 10 seconds, and the energy is moderate. At Bikini, a beach and point setup, that glassy surface will make these small waves feel much better. Crowds are often here, so you’ll have some company.
From Sunday the 19th, things get messy. Monday the 20th sees a spike in swell to 6-7ft from the SE, but the wind is a strong cross-shore, making it choppy and poor. The energy is strong, but it’s not worth it. For a few days, it’s better for kite surfing than paddling.
We get a cleaner lull from Wednesday the 22nd to Friday the 24th with small, clean surf in the 2ft to 4ft range, but it’s all very ordinary. Nothing exciting.
Then there’s a decent window on Saturday the 25th. The morning shows a 2ft S swell with a very long 13-second period and light offshore winds from the N. The energy is moderate. That long period groundswell will wrap nicely into the point. By the afternoon, it goes glassy with 2ft S swell at 12 seconds. This is the second-best option, but it’s still small.
After that, from the 26th of July to the 1st of August, it’s a long stretch of poor conditions. The wind is mostly onshore or cross-onshore, and the swell is tiny. There’s a spike in energy on the 1st of August, but it’s with a strong 22 mph cross-onshore wind, making it lumpy. The 16-day window ends weakly.
So, your best bet is the 18th of July (Saturday) for small, glassy waves. The 25th of July is a promising but less certain option for long-period groundswell. The rest is a long stretch of poor or very ordinary conditions. Don’t plan your trip around it.
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.
