The Lowdown
Alright, let’s talk about what’s happening at Bikini over the next couple weeks.
Water temp’s about 53°F, which is pretty standard for this time of year – nothing out of the ordinary. But the surf story for the first week is a tough one. From Saturday the 25th through Wednesday the 30th, it’s mostly flat, weak, and blown out. Swell heights are under 2 feet, winds are onshore or cross-onshore, and the combined energy is mostly in the weak range (54 to 137). Not worth suiting up for much of that.
Thursday the 30th morning is the first real glimmer of hope. Skies clear, wind goes glassy, and we’ve got a clean 3-foot south swell with an 11-second period. The energy bumps up to 204 (moderate). That’s a solid morning window – glassy and clean at Bikini. The afternoon goes back to junk though, with cross-onshore wind.
Friday the 31st and Saturday the 1st of August stay small and clean-ish but nothing exciting – waist-high dribble. Then Sunday the 2nd and Monday the 3rd see a bump in size to 5 to 7 feet from the east, but the wind turns messy or onshore, so the quality tanks. The energy gets strong – Sunday afternoon hits 617 – but it’s choppy and onshore. That’s more of a kite day.
Tuesday the 4th afternoon is another standout: clear skies, glassy wind, a 5-foot east swell with a 10-second period, and good energy at 427. Clean, punchy, and fun for advanced surfers. Expect crowds – Bikini’s often packed. Wednesday the 5th morning keeps the good streak with offshore NNE wind at 6 mph, 3-foot east swell, and clean conditions. Another nice session.
After that, the second week fades into smaller, messier waves. Nothing really worth highlighting from the 6th onward – east swell sticks around but winds turn bad, energy drops, and it’s mostly choppy.
Bottom line: hit Thursday 30th July morning for that glassy 3-foot south swell, and Tuesday 4th August afternoon for glassy 5-foot east swell. The rest is mostly a wait-and-see.

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.
