The Lowdown

Alright folks, Rusty here. Let's get into it. We're looking at a pretty grim run for Bikini over this forecast period. Don't get your hopes up; we've got a long wait ahead.

The first week is a write-off. Starting from August 8th right through to the 13th, it’s poor conditions across the board. Strong cross-onshore winds in the 25-25 mph range are just wrecking any chance of a clean wave. The water's sitting at 54°, which is a touch warmer than normal for this time of year, but you won't feel it with that wind ripping through you.

We finally see a glimmer on the morning of Friday the 14th. It's not much, but we get clean conditions with light east winds going cross-offshore. The swell is a small 4 ft from the SSE with a period of 12 seconds, which is a decent groundswell. The combined energy is moderate at 376. It's a clean, glassy start, but the size is tiny. Later in the day and into Saturday the 15th, the swell drops right off.

Then, on Sunday the 16th, things get interesting. The morning is marginal with a clean 5 ft easterly swell, but the standout is the Sunday afternoon session. We get light rain, but the wind goes light from the NE, making it cross-offshore and clean. The swell is a touch smaller at 5 ft from the east with a 9-second period, but the energy reading of 301 is solid. The conditions are labelled as "expect good surf conditions". This is your best bet for the whole period. It's a beach and point break, and with a south swell direction, it will be working. It's a bit tricky with that short period, but the clean faces should offer a few fun ones.

After that, we're back into the doldrums. From the 17th through the 21st of August, it's a mix of onshore winds and messy conditions. We see a pulse of swell on the 18th with 7 ft SSW at 8 seconds, but the wind is howling cross-shore at 16 mph, making it a complete mess. That energy reading of 647 is strong, but it's all wind-chop.

The very tail end, around the 22nd of August, offers another small window. Saturday morning has clean offshore winds from the NNE with a tiny 2 ft SSE swell. The energy is a weak 100. Saturday afternoon goes glassy with a light easterly, but the swell is down to 2 ft. It's surfable if you're desperate, but there's no power in it.

So, the one true standout is the afternoon of Sunday the 16th of August at Bikini. Keep your eyes on that. Everything else is either blown out or flat. For a spot that's usually very consistent, this is a tough stretch.

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.
