Table - best surf conditions forecast for Bikini over the next 16 days.
Alright, let’s talk about Bikini. This is a beach and point break that’s exposed and very consistent, but it’s advanced territory – not for the faint of heart. The usual optimum swell direction is from the south, but we’re not getting much of that over the next two weeks. The water temperature is sitting around 51.4°F, which is pretty average for this time of year – nothing unusual.
The forecast kicks off this Friday morning, July 10, with a small 2.6ft ESE swell from a groundswell around 11 seconds. Winds are light cross-off, so it’s surfable but ordinary – nothing to get excited about. Friday afternoon just gets worse with stronger cross-off wind and lumpy conditions.
Now, Saturday morning July 11 – that’s the real standout. The wind goes totally glassy, calm as a lake. We’ve got a 3.0ft ESE swell, still 11 seconds, and the combined energy is moderate (549). It’s clean, it’s small but fun, and the lack of wind means you’ll be surfing smooth, peeling waves. Sure, the direction isn’t the ideal south, but when it’s that glassy you take it. Crowds are often around here, so expect company. If you can get out early, you’ll be rewarded.
Saturday afternoon, though, the wind swings around to a cross-onshore WSW breeze, and the swell period drops to 14 seconds but it’s messy – poor conditions.
Sunday July 12 is a write-off: strong onshore SW wind, 6.6ft short-period swell, choppy and lumpy. Not for paddle surfing – maybe more interesting for kite surfers.
Monday July 13 through Tuesday July 14 offer tiny 2.0–3.0ft ESE swells with light to gentle offshore winds, keeping conditions clean. But the energy is weak (189 down to 146) and the waves are small – you’ll get a few but nothing special.
Wednesday July 15 through Thursday July 16 are similar: tiny 2.0–2.3ft E swells with gentle offshore NNE winds. Clean but small, and the energy is very low (46–56). You could paddle out for a few, but it’s pretty average.
Then from Friday July 17 onward, it’s mostly poor. The swell drops to 0.7–1.3ft, then picks up again but with onshore winds. There’s a stretch of days with cross-on winds and lumpy conditions. The only slight glimmer is around Monday July 20 afternoon when a 5.6ft S swell shows up, but it’s cross-on and choppy – marginal at best.
Later in the second week, Wednesday July 22 has a 3.3ft S swell with glassy conditions in the afternoon – that could be a decent session if you’re desperate, but it’s nothing to write home about.
The real beast is Saturday July 25 afternoon: a 8.2ft SSE swell with a 12-second period and massive combined energy (3112). But the wind is a moderate cross-onshore, so it’ll be a lumpy mess – only for experts who

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.
