Alright, surfers, Rusty here, and we’re looking at the Bikini stretch over the next couple of weeks. Let’s be straight with each other: the first week and a half or so is a write-off for quality waves. It’s a real frustrating run of onshore slop and messy cross-shore junk until we get to the back half of the month. But hold tight, because there’s a window of clean conditions that makes it worth sticking around for.

Right now into early July, the wind is howling from the SW and SSW, hammering Bikini (a beach and point setup) with onshore flow. The swell is mostly short-period windswell from the south, so the wave energy is moderate at best. The water temp is sitting at about 53°F, which is pretty much normal for this time of year. Don’t even bother paddling out Thursday afternoon or Friday; it's just messy.

Saturday the 4th and Sunday the 5th see the swell drop off, but Saturday stays cloudy with a cross-on breeze. The real glimmer of hope comes Sunday morning the 5th. The sky clears, the wind drops to a glassy 3 mph from the NE, and we’ve got a clean 4ft groundswell from the ESE with a nice long 10-second period. The combined energy is moderate. This is the first genuine chance for a smooth, clean session at Bikini. The glassy surface is a major positive. Keep in mind that with this longer period, the point break section of Bikini could offer the best shape, but the beach might be a little fat.

From Monday the 6th through to the end of the second week, it’s a total mixed bag. Wind swings back onshore, and the swell gets messy again. There will be some bigger days around the 7th (7ft from the SW on Tuesday morning, but with a brutal 25 mph cross-wind) – that’s expert-only territory with the size, and the conditions will be ugly. Honestly, that setup with strong cross-wind and decent swell at a beach break might be more interesting for kite surfing than a paddle.

Now, the real standout, the one you want to plan for, is Tuesday the 14th and Wednesday the 15th. On Tuesday morning, we finally get a clean cross-offshore breeze from the N at just 6 mph, with a nice 5ft groundswell from the ESE. The period is a solid 11 seconds, giving those waves some punch, and the combined wave energy is strong. Paddling out will be a breeze between sets. Wednesday morning is the absolute pick of the whole run: offshore wind from the N at 12 mph, a consistent 4ft swell with a very long 12-second period from the ESE, and clean lines. This is quality groundswell, and it’s best taken on the point at Bikini. The water will feel about average for July.

Crowds at Bikini can be an issue, so expect some company, especially in that Sunday window and on those clean mid-week days. Even the Thursday morning the 16th is clean with a 10th period swell from the ESE, but by the afternoon, the wind turns onshore and chops it up.

So, the best I can do for you is point straight at Sunday morning the 5th for a glassy starter, and then lock in Wednesday morning the 15th as the real high point of the outlook. It’s a long wait for the good stuff, but when that offshore wind and long-period groundswell line up, Bikini shows its class.

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.
