The Lowdown

Alright, Rusty here. Let’s break it down.

We’re looking at a pretty bleak run for the next couple of weeks. There’s a gap of nearly a week with no real surf to speak of. The first decent chance doesn’t pop up until the morning of Wednesday, August 7th, but even then it’s just ordinary. The first real standout is a long way off.

Bikini (beach and point) is the only break on the cards, and it’s a tricky one. For a place that’s exposed to the south, the swell direction is often off. The water temp is sitting around 53°F, which is about normal for this time of year.

The whole first week is a write-off. From Wednesday, July 29th through to Tuesday, August 5th, it’s all poor surf conditions. Tiny swell, usually under 2 ft, and the wind is never quite right. You get some clean conditions on the Thursday morning (July 30th) with a clean cross-offshore breeze, but the swell is a pathetic 1 ft with a long 13-second period. That’s a groundswell, but there’s no energy to push it – combined energy is only 87. Not worth paddling for.

On Friday, August 1st, the wind goes offshore, but it’s strong at 22 mph, and the swell is just 1 ft. It’s too much wind for such a tiny wave. Saturday, August 2nd, sees a bump in swell to 3 ft, but it’s cross-shore and messy.

The first hint of something better is on the afternoon of Tuesday, August 5th. The wave comment calls it “surfable waves but very ordinary conditions” – that’s generous. It’s a 3 ft SSE swell with a clean cross-offshore breeze, but it’s only scoring a 1 out of 10. Not a standout.

The real action, if you can call it that, is way out on the horizon. The period from Monday, August 11th, to Wednesday, August 13th, sees a decent pulse of swell. The Monday morning (August 11th) brings a 3 ft SSE swell with a 13-second period, combined energy of 372, and a light cross-offshore breeze. That’s the best-looking window. The afternoon of that same day is even better on paper: 4 ft swell, 12-second period, glassy conditions, and a combined energy of 400. That’s the standout of the whole outlook. The wind is glassy, which is a massive positive. The swell direction (SSE) is a bit off for Bikini’s optimum (S), but with that energy and clean conditions, it’s worth a look.

However, Bikini is inconsistent, and this spot is a beach and point. With a long-period swell like that (12-13 seconds), the point might offer better shape than the beach. Also, the crowds are “often” here, so expect company if you go for that Monday.

After that, the Thursday (August 13th) morning looks okay with a 3 ft SSE swell and clean cross-offshore wind, but it’s a step down.

The big news is the only real standout is that Monday, August 11th, afternoon. It’s a long way off, so don’t set your watch by it, but it’s the best bet in a very quiet 16 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.
