Alright folks, Rusty here. Let’s talk about what’s coming up at Bikini.

We’re looking at a pretty tough start to the forecast period. The first few days are mostly a write-off with gusty onshore winds and messy conditions. There’s a big gap where you won’t want to bother, but things do turn around eventually with a couple of standout windows, especially later on.

Right now, Friday the 3rd and into Saturday the 4th, it’s a no-go. Strong south-southwest winds are blowing straight onshore and the surf is either too big and lumpy or just poor quality. The swell energy is moderate (1081) on Friday morning but it’s all wind-affected and sloppy.

Sunday the 5th of July is the first real glimmer. The wind goes glassy calm in the morning with clean conditions. The swell is small, around 3ft from the east-southeast, with a period of 10 seconds. The combined energy is weak (221), so it’s not powerful, but it’s clean and surfable. This is a good option for a longboard or a fun morning out. By the afternoon, it gets a bit tricky with a light cross-shore wind.

Then we hit another dry spell. From Monday the 6th right through to the 13th, it’s mostly cross-onshore winds, lumpy, choppy, and generally poor. Swell stays small and energy is low. There are a couple of moments – like Monday morning the 13th with glassy conditions and a tiny 2ft swell – but it’s barely surfable and very ordinary.

Now here’s the goods. The real standout comes on Friday the 17th of July and into Saturday the 18th. We’ve got a clean, long-period south groundswell rolling in. Friday morning sees 6ft from the south at 12 seconds, with light east winds blowing cross-offshore, keeping it clean. The combined energy is strong (886). Friday afternoon stays at 5ft from the south with a 14-second period and clean conditions again. And then Saturday the 18th morning holds with 4ft from the south-southwest, light cross-offshore winds, and strong energy (655). At Bikini, with a south swell direction matching the optimum and those clean winds, this is the best we’ve got. Keep in mind this is a long-period groundswell, so at this beach-and-point setup, expect longer gaps between sets but smoother, more powerful waves. It’s not for beginners, but experienced surfers should be looking hard at that window.

Also worth noting, a smaller pulse on Tuesday the 14th of July brings 6ft to 7ft from the southwest with clean cross-offshore winds, but the period is a short 6 seconds, so it’ll be weak and messy. The combined energy (253 to 407) is moderate, but it’s just not as good as the later window.

So, to sum it up: it’s a long wait, with a poor start and a big gap in the middle. But the end of the second week, specifically Friday the 17th and Saturday the 18th, delivers the real deal. That’s your target.

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.
