The Lowdown
Alright folks, it’s Rusty here, lookin’ at the next 16 days for Bikini. Gotta be straight with you from the jump – it’s a tough stretch. The forecast is a real mixed bag, and we’re gonna have to wait for the magic to line up.
First, the pattern. We’ve got a bit of a messy start with small, weak pulses. The swell energy is low, and the wind is all over the place. For the first few days, it’s gonna be a struggle to find anything decent. There’s a big spike of energy on the 7th, but it’s gonna be a total mess with howling onshore winds, so that’s a write-off for us. After that, we settle into a long period of small, weak, and often wind-affected waves. The water temp is about average for the time of year, nothing to write home about.
Let’s break it down. Wednesday morning the 5th, we’ve got tiny 2ft surf from the SE with a 9-second period. The combined energy is a weak 78, and while the wind is a light cross-off, it’s just not enough to get excited about. The afternoon drops even smaller. Thursday the 6th is worse, with a glassy 1ft morning, but again, it’s barely a ripple. The real kicker comes Friday the 7th. A massive 10ft swell from the S hits, but it’s accompanied by a 25 mph onshore wind. The energy is a whopping 1689, but it’s a total blown-out, dangerous mess. This is strictly for experts, if anyone's crazy enough, and even then, it’s more of a kite-surfing setup than a paddle session.
The whole second week is grim. From the 8th right through to the 20th, we’re looking at a long stretch of poor to marginal conditions. The swell is almost always under 5ft, often with moderate to fresh onshore or cross-shore winds. There are a few moments where the wind turns offshore or cross-off, like on the 14th afternoon with a 3ft SSE swell, or the 19th and 20th with clean offshore winds and 3ft ESE swell. The energy on those days is still weak (around 150-200), but the conditions are clean. The 20th morning has a moderate offshore with a 3ft, 10-second period swell, which is the best of a bad bunch.
The only real standout in this whole 16-day window is that Thursday morning the 20th. The wind is a moderate offshore from the N, the swell is a clean 3ft from the ESE with a longer 10-second period, and the energy is 159. It’s small, but it will be clean and lined up at Bikini, a beach and point break that’s very consistent and exposed to the S. For a point break, that longer period means the waves will have some shape. Just be aware the crowds are listed as "often", so expect some company. It’s the best chance for a few fun, clean waves, but it’s a long way off, so don’t book the trip just yet.
So, to sum it up: there’s a long gap of poor surf from the 7th right through to the 19th. The only flicker of hope is that Thursday the 20th with clean offshore conditions and a small, workable swell. Keep your eyes on the forecast, things can change, but right now, it’s a waiting game.
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.
