Alright folks, Rusty here. Let's have a look at what's cooking for our little slice of paradise at Bikini.

Right off the bat, this is a tale of two extremes. We kick off with a real treat, the best of the whole run, and then things get pretty sour for a long, long stretch before we see a light at the end of the tunnel.

We’re starting this Sunday, July 5th, and it’s magic. The water temp is sitting pretty much where it should be for this time of year, no wild swings there. Bikini is a beach and point setup, and it lives up to its name this morning. We’ve got clean, glassy conditions with a tiny 3 mph breeze from the SSW. The swell is a clean 3ft from the ESE, pushing in at a nice 10-second period. It’s not big, but man, it’s going to be smooth, rippable, and fun. The combined energy is a mild 339, telling you it’s about quality, not power. This is the standout window—Sunday morning and afternoon, it’s all on. This is your time to get wet.

Then, like a door slamming shut, Monday, July 6th rolls in, and it’s a complete washout. We’re looking at strong onshores, messy cross-chop, and a lumpy ocean. That clean little wave is gone, and it stays ugly for days.

The truth is, from Monday the 6th all the way through to Friday the 17th of July, the forecast is pretty bleak. That’s a solid 11-day stretch where the scores are low. We get a few tiny windows of clean-ish conditions with almost no swell, like Thursday the 9th morning with a flat 1ft, but there’s just no push. It’s a frustrating gap, folks. For a spot like Bikini that’s usually very consistent, this run of dud conditions is hard to take.

Now, hold onto your leashes, because the second week brings a monster. The standout of the whole 16-day run is Saturday, July 18th. We get one perfect moment: Saturday afternoon. The wind swings around to a light NNE offshore, blowing clean. The swell jumps to 5ft from the SSE, with a long 12-second period. This is legit groundswell. The combined energy rockets up to 580 (moderate energy), promising some real punch. For an advanced break, this is going to offer some powerful, clean lines. It’s not too big, not too small... it’s just right. The only bummer? Sundays are listed as "often" crowded, and on a day like this, you better bet it’ll be packed.

The next day, Sunday July 19th, the energy gets even bigger, hitting 6ft with a period of 15 seconds and a massive energy of 1567—that’s a lot of raw power. But the wind cranks onshore, turning it into a lumpy, messy close-out. That kind of strength and long period is better for a point or reef, not a beach setup with wind on it. Honestly, that looks more like a kite-surfing session than a paddle-surfing session if you ask me.

By Monday the 20th, the swell is still pushing 6ft (energy 1094), but it’s straight onshore from the SW again and a bit raw. The conditions are marginal at best. That’s a long way out, too, so keep that in mind.

Bottom line: Don’t sleep on this Sunday, July 5th. That’s your golden ticket. The rest of the first week and most of the second is a write-off, but that Saturday, July 18th afternoon is a real beacon of hope. Mark your calendars for those two days.

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.
