The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the cards for Bikini over the next couple of weeks.
Straight up, I gotta be honest with you – we’re looking at a pretty flat and quiet run for the most part. There's a glimmer of hope in the second week, but you’re gonna need some patience.
Tuesday 8th September kicks things off with a tiny bit of swell. We’re talkin' about knee-high, maybe 3ft of SSE swell with a 9-second period. The combined swell energy is weak at 147, and while the wind is light offshore in the morning, there’s just not enough push to get excited about. The water is sitting at 55°, which is a touch warmer than normal for this time of year.
Wednesday the 9th is even smaller, dropping to 1ft, and though the wind goes glassy in the morning, it’s just too small. There’s a real gap of nothingness from Wednesday through to the following weekend – the energy is just pathetic, often below 100, with messy cross-shore and onshore winds. It’s a write-off.
Saturday 12th September sees a bit of a spike in size, with 7ft to 7ft of S swell, but don’t be fooled. The period is a short 8 seconds, and the wind is a fresh cross-onshore, making it choppy and lumpy. The combined energy jumps to 459, but it’s just ugly. That’s a kite-surfing setup, not a paddler’s dream.
We finally get a proper window of hope on Thursday 17th September. The morning brings a clean 4ft of SSE swell, with a 10-second period and a light offshore breeze from the ENE. The combined energy is a solid 320 – moderate, but punchy enough. The conditions are good, and for a break that's very consistent and exposed to the south, this is the standout of the whole forecast. The water will still be feeling a touch warmer than average.
Friday the 18th is still surfable in the morning with clean 3ft waves and a light offshore, but it's smaller. After that, we drift back into tiny, weak waves for the rest of the period. The following week from the 19th onwards is all knee-high or less, with hardly any energy. It’s a classic lull.
So, to sum it up: if you’re keen, save your energy for the morning of Thursday 17th September at Bikini. That’s your best bet. The rest of the window is a tough wait.
Stay patient, and check back in with me.
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.
