The Lowdown
Alright folks, Rusty here. Let’s break down what’s in the water for the Bikini area over the next couple of weeks.
Honestly, I’m not gonna sugarcoat it – this is a lean stretch. The whole 16-day window looks pretty grim for the first week and a half. From Monday, July 27th, right through to Saturday, August 8th, there’s barely a ripple worth paddling for. It’s mostly tiny swell, messy wind, and a lot of onshore chop. The combined wave energy is mostly well under 100 (weak energy), and the swell heights are usually under 3 ft. It’s a total desert. You’d be better off staying home.
The first real glimmer of hope arrives on Sunday, August 9th. The morning session at Bikini (a beach and point break) looks decent. We’re talking a 5 ft swell out of the SSW, with a clean cross-offshore breeze from the north at 9 mph. The energy is moderate at 216, and the conditions are clean. That’s a worthwhile Sunday morning.
But the session to circle in red is the morning of Monday, August 10th. This is the true standout. The swell is a solid 5 ft from the SSW, but the period is a long 11 seconds – that’s proper groundswell. The combined energy jumps to 581 (strong energy), and the wind is light offshore from the NNE at 6 mph. That’s glassy, clean, and has some real push. Bikini is an exposed spot, and this south swell is exactly what it wants. The water temperature is 53° which is about normal for this time of year. This is the best session on offer. The afternoon is still okay, but the swell drops to 3 ft.
After that, it’s back to a mixed bag. The 11th of August has some size (6 ft) but the period is short and the quality is questionable.
So the bottom line: the first ten days are a bust. The clear winner is the morning of Monday, August 10th. Set your alarm.
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.
