Table - best surf conditions forecast for Bikini over the next 16 days.
Hey, this is Rusty. Let's talk about Bikini.
It's a beach and point setup, and I'll be honest, the first week is a bit of a grind. Water temp is right around average for the time of year, so no surprises there. Sunday, July 12th? Forget it. Onshore wind, gutless swell with combined energy at 330 (weak). Not worth the wax.
Monday the 13th gives us a little taste. Light cross-off wind, a 3ft swell from the ESE. The energy is moderate at 222. It's clean, so you might snag a couple, but it's not the main event.
The session to get amped for is Tuesday morning, July 21st. This is it. We've got a clean 5ft swell from the ESE, a gentle offshore wind from the NE, and a combined wave energy of 281 (moderate). The period is short, around 7 seconds, which is actually great for a beach break. It'll keep the waves from getting too fat and will give you some fun, punchy little barrels. Conditions are noted as "clean" and "gentle offshore." That’s your window.
And if you miss that, mark down Monday, July 27th. Both the morning and afternoon are looking solid. Another clean 4ft to 5ft swell from the SSE, with a light offshore breeze. The energy is sitting in the 232-249 range (moderate), and it’s described as "clean" again. That's a great backup session for the end of the run.
The rest of the fortnight? Lots of poor conditions. A lot of rain, thunderstorms in the forecast, and strong cross-onshore winds. The 26th of July is marginal at best with light cross-shore winds creating bumps. Not great.
So here's the takeaway: Go on the 21st. If you can't, the 27th will treat you right.
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.
