The Lowdown

Alright, folks. Rusty here. Let’s have a look at what the next couple of weeks are serving up for Bikini.

Right off the bat, I gotta be straight with you: this is a pretty grim stretch for the most part. We’re looking at a long, dry spell with almost nothing worth paddling out for. The first real glimmer of hope doesn’t show up until the 11th of August, which is a solid two weeks away. There’s a lot of small, weak, or messy days to get through before that.

Let’s break it down. Starting on the 27th of July, Monday morning, we’ve got a tiny 2ft easterly windswell with a weak energy (38), and the wind is offshore from the NNE, so the surface is clean. But the waves are just too small and poor. The afternoon picks up a 1.0ft, 13-second south swell, but it’s still a very ordinary session. The water temp is sitting at 53°, which is about normal for this time of year, so nothing weird there.

Tuesday the 28th and Wednesday the 29th are more of the same: small, short-period slop with cross or cross-onshore winds. Not a single one of these days is worth your time. Thursday the 30th has a cleaner look with a 1ft SSE swell and a long 12-second period, pushing the energy up to 98, but it’s still tiny. The afternoon gets a bit of a bump with a 2ft south swell and 11-second period, with energy hitting 103 (moderate), but the wind is a stiff 16 mph cross-offshore. It’s clean, but the size is not there.

Friday the 31st is a complete write-off – fresh offshore winds but the swell is all over the place. The first week of August is just a blur of poor conditions, onshore winds, and small, weak waves. The energy picks up a bit on the 4th of August, with 4ft SSE swell hitting 274 (moderate to strong), but the wind is cross-offshore and the comment says it’s marginal. It’s a tease.

Now, the 5th of August, Wednesday morning, we get a bit of a reprieve. Light offshore winds from the NNE and a 4ft SSE swell with a 9-second period. The energy is at 182 (moderate). It’s surfable, but the comment says "very ordinary conditions." The afternoon holds up with a similar 4ft SE swell, but again, just ordinary.

The 6th of August is a mess – strong cross-onshore winds, lumpy, forget it. The 7th of August, Friday morning, is another clean offshore day with a 3ft south swell, but the period is a short, weak 5 seconds, and the energy is only 103. It’s a knee-high ripple at best.

The 8th and 9th are a washout, with onshore winds and poor surf. The 10th of August, Monday, is the same story – fresh cross-onshore winds and lumpy.

Then, finally, we get to the standout. Tuesday, the 11th of August. This is the one. The morning is glassy, with a 3ft south swell rolling in with a deep, long 13-second period. The combined energy is a solid 403 (strong). The afternoon is just as good, with a 4ft south swell, a 12-second period, and energy at 384 (strong). The wind is glassy in the morning and just a light air in the afternoon. This is a proper groundswell. For a beach-and-point break like Bikini, a long period south swell like this will line up nicely on the point. The water is still cold, but the conditions will be clean and the waves will have some punch. That’s your window. It’s an advanced wave, so it’s not for the faint of heart, and the crowds can be an issue, but for a crew that knows what they’re doing, this is the best the forecast has to offer.

After that, the outlook fades out again. It’s a long wait for a short burst of good stuff, but that 11th of August is worth marking on the calendar.

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.
