The Lowdown
Alright folks, Rusty here. Let’s talk about what’s shaping up at Bikini. This is a spot that needs a solid south swell to come alive, and we’ve got a big pulse of energy headed our way, but it’s going to take a few days for the wind to play nice. The water is sitting at 51.4°, which is pretty much bang on average for this time of year, so no surprises there.
The overall pattern starts with a whole lot of wind and messy, blown-out conditions. Saturday the 22nd and Sunday the 23rd are a write-off – strong cross-onshore and onshore winds, lumpy and ugly. The swell is actually there, with a solid 8.2ft of south groundswell on Sunday and a huge combined energy of 2877, but it’s just not rideable. You’d be a glutton for punishment.
Then, Monday the 24th morning is where it finally clicks. The wind drops right out – glassy conditions – and we’ve got a clean 5.9ft swell from the SSE (1298 energy). The period is a solid 12 seconds, so it’s a proper groundswell with good shape. This is a standout: the best of the whole run. The break is a beach and point setup, so that long-period swell will wrap around the point nicely. Just be aware that crowds are often here, so get in early.
The quality holds through Tuesday the 25th morning with a gentle offshore NE wind and 3.9ft of SSE swell, but it’s a bit smaller. Wednesday the 26th is another gem – morning offshore NNE breeze, 4.6ft of SE swell with a long 14-second period and 731 energy. The waves will have plenty of push and be clean all day. This is the second standout. The swell direction is south-southeast, which is just about the optimum for this exposure.
After that, the size drops off quickly. Thursday the 27th morning is still glassy but only 3ft, and from Friday the 28th onward, we’re looking at a long stretch of small, weak, and mostly wind-affected surf. The energy drops to triple and even double digits. There’s a gap of poor conditions from the 28th of August all the way through to the 5th of September, with only a couple of very ordinary, clean but tiny days on the 1st of September. The small pulses on the 6th of September show some south swell returning, but it’s onshore and messy again.
So, the call is simple: Monday the 24th and Wednesday the 26th are your days. The rest is a waiting game.

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.
