Table - best surf conditions forecast for Bikini over the next 16 days.
Alright, let’s break this down for Bikini—a beach and point setup that’s gonna test your patience for a bit before giving you a little reward.
Water temp is sitting at 52°, right where it should be for this time of year.
The first real action kicks off on Saturday, July 11th. Thursday and Friday are pretty weak: small east swell around 2-3 ft with short to moderate periods, and the wind just isn’t cooperating. Thursday morning has some cross-off wind but the swell is tiny. Friday is cross-on and messy.
Now, Saturday the 11th – the morning brings 3 ft from the ESE (11-second period) with 15 km/h cross-off east wind—clean conditions. The energy is building (415). By the afternoon, the swell holds at 3 ft from the ESE, the period stretches out to a nice 14 seconds, and the wind drops to a light 10 km/h from the east, still cross-off. That’s the standout window: clean, long-period groundswell, with moderate to strong energy (506). Bikini’s point should handle that ESE swell nicely, giving you proper shaped waves. Just a heads up—crowds are possible on a Saturday.
After that, it fades quickly. Sunday the 12th gets onshore, dropping to smaller, weaker surf. Monday the 13th has a brief glassy afternoon, but only 2 ft and weak energy—worth a look if you’re local and bored. Tuesday through to Wednesday the 22nd is mostly flat or tiny, with rain and stronger winds making it unappealing.
There’s a gap of almost two weeks before we see any real size again.
Then, Thursday, July 23rd shows a jump: 6 ft from the SSE in the morning, hitting 7 ft in the afternoon, but it’s short-period windswell (7 seconds) with a moderate 25 km/h cross-off wind. That’s getting into expert territory at 7 ft, and the short period means it’ll be lumpy and less refined. Friday the 24th morning is interesting: 5 ft from the south, still short period, but glassy with almost no wind. That could give you some clean, punchy waves, but it’s strictly for experienced surfers at that size. Energy is moderate (268).
So, the best bet is Saturday the 11th afternoon—3 ft, clean, long-period groundswell, light wind. If you’re an experienced surfer, keep Friday the 24th morning in the back of your mind for a glassy, powerful 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.
