The Lowdown

Right, let’s have a look at what’s on offer for Bikini over the next couple of weeks. It’s a bit of a mixed bag, to be honest. There’s some swell coming through, but the wind is going to be a real pain for most of the first week, making things pretty messy. Don’t get your hopes up too high for anything clean until we get closer to the end of the month.

We’re looking at Bikini, a beach and point setup that’s exposed to the south. The water temp is about average for the time of year, nothing to write home about.

The first few days, from Monday the 17th through to about Wednesday the 21st, are mostly a write-off. We’ve got some swell – a mix of short-period stuff from the east and southeast, with wave heights ranging from 2 ft to 6 ft – but the wind is stubbornly cross-onshore or onshore, and it’s choppy or lumpy. The energy is mostly weak to moderate. Not worth paddling out for.

Thursday the 22nd and Friday the 23rd see a big jump in swell energy, hitting a crazy high level on the Saturday morning and then a massive one on the Sunday afternoon. The swell height gets up to 10 ft from the south-southwest. But the wind turns nasty – strong to near-gale force cross-onshore winds. That much power with that wind means it’s blown out and dangerous. Honestly, for anyone but the most experienced, this is a skip. If you’re into kites, that setup on Saturday and Sunday with the strong wind and big swell might look more interesting than paddle surfing.

We get a bit of a breather on Monday the 24th. The swell drops to 6 ft from the SSE with a long 11-second period, and the wind goes light onshore. The energy is still high. The conditions are only marginal. The long period could make it a bit tricky at the beach break, but the point might offer something.

Now, Tuesday the 25th sees a bit more promise. The wind goes light, almost glassy in the morning (3 mph from the SSE), with a 4 ft SSE swell at 10 seconds. The energy is moderate. It’s still a bit cross-on, but the light wind means it will be clean. This is the first real window for a decent, manageable session.

The real standout, though, is looking like Sunday the 31st of August and Monday the 1st of September, but that’s a way off, so keep an eye on it. The swell is from the ESE at 5 ft with a lovely long 12-second period, and the energy is strong. The wind is light and cross-shore, even offshore on the Monday morning. That’s a recipe for clean, lined-up waves, especially on the point. It’s going to be a crowd-pleaser, and with the spot being “often” crowded, expect some company. This is the best on offer for the whole window.

So, if you’re itching for a paddle, Tuesday the 25th morning is your best early bet. For the bigger, cleaner stuff, keep your fingers crossed for that last weekend of August and into September.

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.
