The Lowdown
Grab your wettie, let’s talk about the next couple of weeks.
Straight up, it’s gonna be a tough stretch for a while. We’ve got a solid run of poor surf ahead, with a bit of a lull at the very start. Honestly, for the first few days, you can probably leave the board in the car. There’s some swell, but the winds and conditions are just messy. We’re seeing a lot of cross and onshore breezes, from the SE and SW, messing up what little energy is rolling in. It’s not looking good.
We’re looking at Tuesday the 2nd as the first real chance to paddle out. Even then, it’s only ordinary – a clean 2ft of east swell, but the period’s short, sitting around 9 seconds. The wind is offshore from the NNE in the morning, which is good, and it’ll be glassy. That’s your window, a tiny one.
After that, we slide back into the doldrums. The wind stays mostly cross or onshore, and the swell just doesn’t have any push. There’s a bit more energy on Saturday the 5th and Sunday the 6th, but it’s bringing strong, messy cross-onshore winds with it. That 7ft of south swell on Sunday morning might have size, but it’ll be a washing machine – more for the kitesurfers than us paddle surfers, especially at a beach and point setup like this.
The next small window opens up on the morning of Tuesday the 8th. We get a clean 3ft south-southeast swell with light offshore NE winds. That’s something, but it’s still just ordinary. The 11 second period in the afternoon is a bit better, but the wind swings cross-off.
Then, it’s pretty much a write-off for the rest of the week. The wind goes onshore or cross, the swell gets mixed up. There’s a moderate push of energy from the 10th, but the conditions are just poor. We see a couple of days with 4ft of east swell, but it’s crossed up and lumpy. Not worth the effort.
We head into the following week and it’s still grim. Strong south-west winds on the 13th and 14th just kill it. By Monday the 15th, the swell drops right off, down to a foot – basically flat. The only thing of note is a 15-second period wrap, but there’s no size to it. The next day, the 16th, we see a little blip of south swell, around 4ft, but the wind is onshore and it’s short period. Just another poor day.
So, for standout days, there aren’t any true jewels. The best on offer is likely the morning of Tuesday the 2nd – it’s clean and offshore, but tiny. Tuesday the 8th morning is probably your next best. It’s got a little more size, and it’s clean. Use the forecast confidence wisely – the later stuff is less certain. As for the water temp, it’s a touch warmer than normal for this time of year, so you might not need the thickest suit.
There are going to be several days with no recommendations, particularly around the 13th and 14th, and then again on the 15th. It’s a bleak run, but these things never last forever. Forecasts change, so keep an eye on it.

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.
