The Lowdown
Hey, Rusty here. Let's talk about Bikini for the next couple of weeks. To be honest, it's a pretty bleak outlook for most of it. There's a big stretch of nothing special, so don't get too excited too soon.
Water temp is around 51°F at Bikini, which is pretty standard for the season.
Kicking off on Saturday morning, August 29, there's a tiny 2ft easterly swell with a 9-second period and only 58 units of energy—real weak sauce. The wind is glassy from the south at 3 mph, so the surface is clean, but the waves are just ordinary. It's barely worth a splash. From Saturday afternoon through to Thursday, September 4, it's almost a solid week of poor conditions—tiny waves or messy onshore wind. Write it off.
The first real chance comes on Monday morning, September 7. A 6ft swell from the SSE, 10-second period, and 592 units of moderate energy rolls in. It's cross-onshore with a light air from the south at 3 mph, so there'll be a few bumps. It's marginal. The afternoon is cross-shore and drops to 5ft.
The standout session is Tuesday morning, September 8. This is the one. A clean 4ft SE swell with a 10-second period and 284 units of moderate energy. The wind is offshore from the NNE at 9 mph, giving you those clean, glassy conditions. This is your best window for a proper surf. The waves should hold some shape, and with offshore wind, it'll be tidy. Expect the spots to be busy.
Wednesday morning September 9 is another option, but it's much smaller—just 3ft from the east with a weak 6-second period and weak energy. The offshore wind from the NE at 9 mph keeps it clean, but it's not going to blow your mind.
As for that Saturday afternoon, September 5—1.8m (around 6ft) of SSW swell but with 28 mph cross-onshore winds and big messy conditions. That's more for the kite crew than surfers.
So, the call is clear: Tuesday morning, September 8 is the one to chase. The rest is a long wait for not much.
Catch you in the water,
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.
