The Lowdown
Alright, my friends, Rusty here giving you the lowdown on what’s cookin’.
First few days it’s small and you gotta play the wind. The water’s a touch warmer than usual for August, which is a nice little bonus.
We start on Wednesday afternoon with tiny 2ft surf out of the SE. It’s glassy though, which is nice, but the energy is weak. Thursday morning stays small and glassy at 1ft, but the afternoon gets a cross-shore breeze that messes it up.
Then Friday morning the 7th, a big pulse of 10ft swell from the south hits, but don’t get too stoked – the wind is howling onshore at 25 mph, making it a total mess. That’s a kite-day, not a paddle-day.
We go through a stretch of lumpy, cross-onshore conditions through the weekend and into early next week. There’s a clean window Saturday morning the 8th with 4ft from the SSE and a cross-offshore breeze, but it’s nothing to write home about.
The first real standout is Wednesday morning the 12th. Glassy conditions again, with a nice 5ft SSE groundswell with an 11-second period. The energy is moderate, but that clean surface is a winner.
But the big one, the one I’m counting down the days for, is Tuesday the 18th. We get a proper south swell that hits 11-12ft with a long period. The energy is massive. The swell direction is SSW, which works a treat here. The wind is light and cross-offshore both morning and afternoon. This is for experts only – way too big for beginners – but for the crew who can handle it, that is the session of the whole two weeks. It’s a long way off, so keep an eye on it, but it looks serious.
Following that, Wednesday the 19th afternoon cleans up with moderate offshore winds and 5ft surf from the south for some very good waves. Thursday the 20th morning stays clean and glassy with a 2ft long-period ESE swell, a nice little finisher to the run.
So, short story: survive the onshore days, surf the glassy Wednesday the 12th, and if you’re a ripper, circle Tuesday the 18th on your calendar.
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.
