The Lowdown
G’day, it’s Rusty here. Let’s get straight into it – the next couple of weeks are a mixed bag, so you’ll want to pick your sessions carefully.
Right now, it’s flat out. Saturday the 1st has next to nothing – a tiny 0.3ft southerly bump, and the water’s at 55°F, which is a touch warmer than usual for this time of year, but still chilly.
From Sunday the 2nd through Wednesday the 5th, it’s mostly grovel. We’re talking ankle-biters – swell heights around 2ft or less, weak energy, and messy winds on and off. Monday the 3rd morning has a clean offshore breeze and a 2ft south swell with an 11-second period, but it’s still very ordinary. You’ll get a few if you’re keen, but don’t expect much.
Thursday the 6th is the first real glimmer. The morning is glassy and tiny, but the afternoon brings a 6ft SSW swell – short period, 6 seconds – but the energy jumps up to 262, which is moderate, and the conditions are clean. That’s a decent window, especially if you can dodge the crowds.
Friday the 7th is messy – the swell drops a bit, and the cross-onshore winds chop it up. Saturday the 8th sees a bigger pulse – 8ft of SSW – but it’s windy and lumpy, so it’s a battle, not a pleasure.
Sunday the 9th turns ugly. A strong 45 km/h WSW cross-on wind in the afternoon turns 7ft of short-period swell into a washing machine. That’s kite-surfing weather, not paddle-surfing.
Now, Monday the 10th – that’s the big one. Morning shows 8ft of long-period south swell, 13 seconds, and the energy reading is massive – 2043, jumping to 4361 in the afternoon. That’s serious power. The wind is cross-shore from the WNW, so it won’t be glassy, but there’s a ton of juice. This is well over the 8ft mark, so it’s only for experienced surfers – beginners, sit this one out. The long-period swell will be best on Bikini’s point and reef sections, likely going too straight on the beach.
Tuesday the 11th still has size – 5ft of south-southwest swell in the morning, clean with a cross-offshore NW breeze. But the afternoon is a loss – strong WSW winds and messy conditions.
Wednesday the 12th is a nice little reset – clear morning, light cross-offshore, a 3ft south swell with a 10-second period. Clean and fun, not big, but a good session.
Thursday the 13th and Friday the 14th are small again, and Friday brings a 8ft S swell but with a strong onshore wind – messy.
Now, Saturday the 15th – another potential standout. Morning shows 8ft of SSE groundswell, 12-second period, with a cross-offshore NW breeze. Energy is huge at 3548, and it’ll be clean. Again, that’s expert territory – over 8ft. It’s a ways out, so consider it promising but not locked in.
Sunday the 16th fades – 6ft SSE but with strong onshore winds, so it’s a letdown.
Bottom line: the first five days are a wash, but there’s action from the 6th on. The two big standouts are the 10th and the 15th – big, powerful south groundswells, but you’ll need to know what you’re doing. If you want cleaner, smaller waves, the mornings of the 12th and 15th are your best bets.
Stay sharp, and keep an eye on that wind.
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.
