Table - best surf conditions forecast for Bikini over the next 16 days.
Alright folks, Rusty here. Let’s take a look at the next 16 days for Bikini. To be real with you, it’s a bit of a slow burn at the start. We’ve got a lot of poor conditions and choppy water to get through before things start looking up. Hold tight.
The first window of any real interest kicks off on Monday, 13 July. We’ve got a morning session that’s worth setting the alarm for. The swell is coming in at 4 ft from the ESE with a short period of 7 seconds, so it’s not packing a ton of power, but here’s the thing – the wind is glassy, dead calm from the NE. That means the surface will be like a mirror, and those waves will be clean. The combined energy is moderate (232). It’s a small, clean, fun-sized wave for the advanced crew. It’s not a stand-out in size, but for the start of the week, it’s the best we’ve got.
That sets up a nice little run. Tuesday, 14 July morning builds on it with a similar 4 ft from the ESE, but the period stretches to 10 seconds, giving it a bit more shape and a longer wait between sets. The wind is offshore from the NNE at 15 km/h, so expect clean faces and a bit of push. Combined energy is still moderate (233). This is probably the pick of the early week. The afternoons are surfable but ordinary, so get it while it’s fresh.
Wednesday and Thursday, 15-16 July, drop off a bit in size (3 ft-3 ft) and the wind remains offshore, but the energy drops away. Conditions are clean, but the waves are lacklustre for the advanced crew. By Friday and into the weekend, the swell fades out to almost nothing – 1.0 ft to 2 ft – and the energy is weak. We’re looking at a real flat spell from the 18th through the 19th, with onshore winds and poor surf.
Then we get a weird spike. Tuesday, 21 July sees a jump to 5 ft from the SSE, with a period of 11 seconds and a strong combined energy of 467. But the wind is honking at 25 mph from the east, cross-off and clean in theory, but it’s a strong breeze. For a beach-and-point setup, this is going to be a wind-blown mess. Honestly, this setup looks more interesting for kite surfing than paddle surfing. The swell is there, but the quality is shot.
The real standout for the whole outlook, and the one to circle on the calendar, is Thursday, 23 July afternoon. Out of nowhere, we get a pulse of 6 ft from the E, but the period is a weak 7 seconds. The wind is cross-shore from the ESE at 12 mph, and the combined energy is moderate (328). It’s a short-period swell, so it’ll be a bit lumpy and disorganised at the beach, but for a point break, it might offer some fun runners. The water temp is sitting at 11°C, which is about average for the time of year, so don’t forget a thick wetsuit.
After that, Friday 24 July through Sunday 26 July, the swell stays around 4 ft to 5 ft, but the wind is either strong onshore or cross-shore, making it a write-off. The energy is there (360-374), but the conditions are poor. The last few days of the outlook are a mixed bag of lumpy, choppy, and onshore mess.
So, to keep it simple: Monday 13 July morning for the glassy, clean start, and Tuesday 14 July morning for the best combination of shape and offshore wind. That’s your window. Everything else is either flat, blown out, or a kite surfer’s dream.
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.
