The Lowdown
Alright folks, Rusty here. Gotta be straight with you – this upcoming stretch is a tough one for Bikini. We’re looking at a long, quiet patch right off the bat, with nothing really worth paddling out for over the first few days. The swell is tiny and the winds are mostly cross or cross-off, keeping things clean but weak. The water temp is sitting at 54°, which is a touch warmer than normal for this time of year, so at least you won’t freeze waiting for a wave.
We finally see a little life start to build on Monday, August 3rd. The morning stays ordinary with a 3ft S swell and 11-second period, but the afternoon picks up some energy. That’s when we get a 3ft SSE swell with a period of 11 seconds, pushing the combined energy to 202 (moderate). The wind is a light 6 mph breeze from the east, keeping things clean. It’s not firing, but it’s the most surfable it’s been – a solid option for a longboard or a fun little cruiser.
The rest of the first week goes downhill fast. Tuesday and Wednesday drop off, and by Thursday, August 6th, we’re down to 1ft and almost no energy. Then things get weird. From Friday, August 7th through to the following week, we get a big spike in swell – but it’s all wrong. The wind turns brutal: strong onshore and cross-onshore, ripping in from the west and southwest at 25-28 mph. The swell height jumps to 8ft on Saturday, August 8th, and the combined energy rockets up to 759 (strong), but it’s a messy, short-period 6-7 second wind swell. The waves will be blown out, lumpy, and pretty much unsurfable for a paddle. Honestly, if you’ve got a kite, this might be your window – the wind is solid and the swell is up, but for a surfboard, it’s a pass.
By the second week, the strong winds ease off, but the swell stays confused. Around Thursday, August 13th, we’ve got a 3ft SSE swell with a 13-second period, but the wind is still a fresh 22 mph cross-off, leaving it clean but not exactly inviting. The real standout pops up on Friday, August 14th. The morning turns glassy – a light 3 mph SSW wind, near calm, with a 2ft SSE swell rolling in on a 12-second period. Combined energy is 284 (moderate), and the conditions are described as glassy. It’s a small, clean window, but for a surf that’s not going to fight you, this is the best of the whole run. Don’t expect power, just easy, clean little lines.
The last few days of the forecast show a slight uptick in wind quality, with some offshore breezes on Monday, August 17th, but the swell remains small and the energy is weak. Nothing to write home about. Overall, we’ve got a lot of nothing, one brief clean window on the 14th, and a blown-out period in between. Not our finest hour.
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.
