The Lowdown
Alright folks, Rusty here with a look at what’s on the cards for Bikini over the next couple of weeks.
Honestly, the first week and a half looks pretty grim. We’ve got a long stretch of small, weak, and generally messy surf. From Wednesday the 15th to Sunday the 27th of July, it’s mostly a write-off. There’s nothing worth paddling out for, with a whole lot of onshore and cross-shore winds, rain, and tiny, weak waves. It’s one of those runs where you’re better off keeping the board in the car and hoping the forecasts change. The combined wave energy is mostly below 100 (83-92) for the first few days, and even when it jumps a bit later, the wind just ruins it.
Now, if you’re a patient surfer, there is a light at the end of the tunnel. The real standout, and the only window worth circling on your calendar, is Monday the 27th of July. This is the one. The whole day is looking excellent. The morning brings a glassy, clean 5ft swell from the SSE, with a long period of 12 seconds and a combined energy of 610 – that’s solid, powerful groundswell. The wind is dead calm, so it’ll be perfect. The afternoon keeps it going with a 5ft SSE swell at 12 seconds (589 energy) and a light offshore breeze from the east. This is proper, high-quality surf. The wave comment says it all: “expect very good surf conditions”. This is the one to get excited about.
The water temp is sitting at 51°, which is about average for the time of year, so nothing unusual there.
Monday 27th July at Bikini is the clear winner. The swell direction from the SSE is working well with the break’s optimum from the south, and we’ve got light offshore winds. It’s a beach and point setup, so that long period groundswell should wrap in nicely. This is for the advanced crew, and expect crowds as it’s “often” busy.
The rest of the outlook after that is a letdown. Tuesday the 28th and Wednesday the 29th drop back down to small, ordinary conditions.
So, in short: suffer through the next week and a half, and be ready for a stellar session on Monday the 27th. That’s the one.
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.
