The Lowdown
G'day, this is Rusty.
Look, I'll be straight with you—this isn't a classic stretch. The next few weeks at Bikini are a real mixed bag. For the first week and a bit, it's pretty grim. We're looking at a long dry spell from Friday the 17th right through to the end of the following week, with nothing really worth suiting up for. The water's sitting at 52°F, which is pretty much bang on for this time of year, so no excuses there.
Things are dead quiet initially. Friday the 17th is a no-go: tiny 0.6ft of east swell with a short period, and onshore winds. Saturday the 18th is a write-off. Sunday the 19th offers a brief pulse of 2ft from the SSW, but the period is a pathetic 5 seconds, so it's just crumbly, weak junk. The whole first week, from the 17th right through the 24th, is a solid block of poor to marginal conditions. There's a bit of knee-high swell around, but the winds are a disaster—cross-onshore slop, onshore junk, or just messy. It's a barren run.
Then we hit Saturday the 25th of July, and that's one to circle. The morning shapes up nicely. A solid south swell rolls in at 4ft, and the period is a juicy 12 seconds—real groundswell, with proper energy. The combined energy reading is a meaty 532 (moderate to strong), so there's genuine push behind it. The wind is a clean cross-off from the ENE, which is a major positive. This is the standout of the whole outlook. The wave comment says "expect very good surf conditions," and with that size and clean wind, it's the best on offer. The afternoon stays rideable, but the wind picks up, so the morning is the pick.
Sunday the 26th is a bit of a letdown. The swell holds around 4ft to 5ft with long period, but the wind swings onshore, and it gets messy. The energy is still strong (609 and 619), but the conditions turn poor.
The following week, from the 27th of July through to the 1st of August, is a slow fade. The swell drops, the winds are mostly onshore or cross, and the scores are consistently low. The last day, Saturday the 1st of August, is a final whisper of surf with a tiny 1ft south-southeast swell and glassy conditions in the morning. It's knee-high at best, but if you're desperate for a clean, small wave, it's there.
The one true highlight on the table is the morning of Saturday the 25th of July. The 4ft south swell, 12-second period, and clean offshore wind make it the only session worth chasing. The rest of the window is a waiting game.
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.
