Table - best surf conditions forecast for Bikini over the next 16 days.
Alright, Rusty here. Let’s break down what’s up for Bikini.
Water temp is around 51°F, which is dead average for this time of year – nothing unusual.
First part of the outlook is pretty slow. From the start there’s a long stretch of small, unremarkable surf right through until Tuesday, July 15th. You’ll see waves mostly from 2ft to 3ft, with weak energy readings (between 93 and 413), and conditions are just so-so. Nothing’s really worth paddling out for until we get a bit more juice.
The one true standout, and the only day I’m really excited about, is Tuesday, July 22nd. Bikini gets a nice push of swell – about 5ft from the SSE, with a 10-second period. That’s a proper groundswell, and the energy reading is a solid 373. Wind’s light from the ENE, so expect clean, cross-off conditions. This spot is for advanced riders and it’s very consistent, so you’ll score. Just know it gets crowded often, so get there early. That’s your best bet, no contest.
Later on, around Thursday, July 24th into Saturday, July 26th, the swell gets bigger – up to 7ft and even 8ft from the east and southwest. But the wind turns messy, cross-shore and strong, so it’ll be lumpy and choppy. Not the kind of conditions you want unless you’re on a kite. It’s big enough for experts only, but the quality isn’t there.
Bottom line: If you can surf Tuesday, July 22nd, that’s the session. The rest is either flat or too sloppy to bother.
This is Rusty, signing off.

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.
