The Lowdown
Alright, I’m gonna level with ya. The outlook for Bikini is pretty grim for most of the next two weeks. We’ve got a stretch of rough conditions, poor surf, and less-than-friendly winds, with only a couple of brief windows that might get the heart pumping. Let’s get into it.
For the first week, it’s mostly a write-off. We kick off on Wednesday afternoon, and it’s just not happening. Swell is tiny at 2 ft out of the east, but the wind is a cross-off. The water temp is 55°F, sitting about 3°F warmer than average for this time of year – feels a touch warmer than normal, just a shame the waves aren’t matching up. Energy is weak as hell, barely 78 in the combined swell energy. It’s poor. Thursday and Friday bring some size but the wind is cross to cross-on, and the period is short and inconsistent. Not worth paddling out for.
The weekend is a real mess. Saturday afternoon gets up to 6 ft from the southwest, but with a 25 mph cross-on wind and a period of just 6 seconds, it’s gonna be choppy, messy, and no fun. Then Sunday sees a jump to 10 to 12 ft from the south-southeast. That’s solid size, but the wind is a fresh cross-on at 22 mph, and the combined energy is through the roof – over 1500 and 2098 – which shows a lot of power but it’s all wind-affected and lumpy. Honestly, that’s more of a kite-surfing setup than a paddle-surfing one. You’d be fighting a losing battle out there.
Monday of the second week is still cross-on and choppy. 4 to 5 ft from the south-southeast, but period is short and the wind is spoiling it. Still no real option here. Tuesday morning shows the first little spark. On the 8th of September, we get 2 ft from the south-southeast with a light NNE offshore wind at 9 mph. The combined swell energy is only 132, so it’s not packing a punch, but it’s clean. That carries into Tuesday afternoon with 3 ft and a moderate offshore from the north. It’s surfable, but it’s very ordinary – only a one-out-of-ten kind of session. Not a standout by any means.
Midweek from the 9th to the 12th is back to rubbish. Tiny waves, cross-onshore winds, and minimal energy – mostly in the 30s and 40s. The 13th of September offers another small window: 2 ft from the south with a moderate offshore from the northeast on Sunday morning, and the same again Sunday afternoon with a gentle offshore from the north-northeast. The combined energy is around 109 and 99. Still small, still only a one-out-of-ten, but it’s clean. Worth a splash if you’re desperate.
Now, the real standout – the one you’ve been waiting for – is on Wednesday the 16th and Thursday the 17th of September. Wednesday morning we get 4 ft from the south, period 10 seconds, and a moderate offshore wind from the north at 12 mph. The combined swell energy jumps to 360 – that’s moderate wave energy, and it’s clean. Plus the afternoon looks good too, 3 ft from the south-southeast, still offshore. That’s a genuine option. Then Thursday morning on the 17th is the highlight of the whole outlook: 5 ft from the south, period 11 seconds, light offshore from the north-northeast at 6 mph, and a combined swell energy of 568. The report calls it “very good surf conditions,” and I’m not gonna argue. That’s the one to mark on your calendar. Afternoon drops slightly to 4 ft with a bigger period of 12 seconds and a cross-off wind, still clean but with some tide concerns. Thursday morning is the pick.
So overall, the first week is a write-off, a long gap of nothing recommendable until the 8th, then another gap until the 13th, then the real action arrives on the 16th and 17th. Stick it out for that Thursday morning session.

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.
