The Lowdown
G’day, Rusty here, looking at the next 16 days for this spot.
The first few days are pretty flat and messy. Nothing to rush for. The first real chance comes later.
Monday the 3rd of August sees a small 3ft south swell with a period of 11 seconds, and a cross-offshore breeze from the NE at 9 mph. The water is 55°F, a touch warmer than normal. The combined wave energy is moderate at 160. It’s surfable but ordinary. The afternoon turns cross-shore and messy.
Tuesday the 4th and Wednesday the 5th are small and weak. Swell drops to 2ft and then 2ft, periods dropping to 10 and 9 seconds. Energy is low (123 and 84). Not worth it.
Thursday the 6th is a dud – 1ft swell, offshore wind, but energy is just 28. Too small.
Then Friday the 7th of August – a big pulse hits: 10ft from the SW with a 9-second period, but a strong cross-onshore wind at 28 mph. The energy is massive at 1407. The afternoon sees 8ft south swell with a 14-second period, but still strong cross-winds at 25 mph. This is kite surfing territory, not paddle surfing. Stay out unless you’re an expert.
Saturday the 8th and Sunday the 9th are still big but ugly. Swell from 6ft to 7ft, periods from 14 down to 7 seconds, with cross-onshore or onshore winds. Choppy and lumpy. Energy is strong (1144 and 722). Not good.
Monday the 10th through Wednesday the 12th keep swell around 5ft to 7ft, but winds stay cross-onshore from the SW or WSW. Periods short (6-10 seconds). Energy moderate to strong (342 to 524). All wind-affected.
Thursday the 13th of August – this is the standout. Swell drops to a clean 4ft from the SSE with a period of 10-11 seconds, and the wind turns light cross-offshore from the NE at 6 mph. Energy is 233, moderate. Conditions are clean. The break is a beach and point, very consistent, exposed to south swells, and the direction matches. Crowds are often, so expect company. This is the best on offer for advanced surfers.
Friday the 14th morning is glassy – no wind, 3ft from the SSE, 10-second period. Energy 155. Small but clean. Afternoon turns cross-onshore.
From Saturday the 15th through Tuesday the 18th, swell drops to 2ft to 4ft, mostly from the east or south, periods 7 to 13 seconds. Winds are cross-off or cross-on, but energy is low (127 down to 31). A few clean moments, but nothing special. The last days on the 18th see a bump to 5ft and 5ft from the SW, but with short periods (6 seconds) and cross-onshore wind, it’s choppy and weak.
Best call: Thursday the 13th of August morning. Clean, offshore, solid swell from the right direction. That’s your window.
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.
