The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s comin’ down the line for the next couple of weeks.

Right off the bat, we’re in a bit of a flat spell. The first recommendation is for Friday the 24th of July, but it’s honestly nothing to get excited about. We’re lookin’ at tiny, 2ft to 2ft southerly swell with a combined energy of just 83, so it’s weak. The wind is off from the NNE, which is clean, but the waves are just too small to really bother paddling out for. The water temp is about average for this time of year, so it’s comfortable enough.

Saturday the 25th is more of the same – 2ft southerly swell, period bumpin’ around 12 seconds, which is decent, but the energy is only moderate at 135. The wind flips to a cross-off from the ENE, keepin’ things clean, but it’s still pretty weak. The afternoon gets a bit of a puff with 16 mph winds, but the energy jumps to 244, so there’s a little more push, but it’s still just marginal.

Sunday the 26th is a write-off. The wind swings onshore from the WSW, and the swell drops to 1ft. It’s a total no-go.

Monday the 27th has a bit of a clean window with offshore winds from the NE, but the swell is only 1ft, and the energy is a paltry 49 to 73. Not worth the wetsuit.

Tuesday the 28th and Wednesday the 29th are a mess. Onshore winds, choppy, lumpy conditions. The swell does build to 5ft on Wednesday, but the period is a short, weak 7 seconds, and the wind is makin’ it ugly. The energy is 235, but it’s all blown out.

Thursday the 30th is a bit of a tease. You’ve got a 4ft southerly swell with a good 11-second period, and the energy is strong at 357. The wind is cross from the ESE, so there’s a bit of chop, but it’s a marginal call. The afternoon cleans up with a cross-off, but it’s still not a standout.

Friday the 31st and Saturday the 1st of August are poor. Strong winds, cross-shore, messy. The swell is small and weak.

Now, Sunday the 2nd of August, the swell picks up to 5ft to 6ft, with a period of 8-9 seconds from the ESE. The energy is strong at 470, but it’s all onshore from the S or SE, so it’s lumpy. The afternoon is a bit more marginal, but it’s not clean.

The real standout in this whole forecast is Wednesday the 5th of August. We’ve got 6ft of ESE groundswell rollin’ in with a long 12-second period. The combined energy is a meaty 1061, so it’s got some serious push. The wind is off from the NNE, which will keep Bikini’s face clean and tidy. This is a solid, punchy swell for experienced surfers. The long period means it’ll be a bit more lined up, and with the offshore wind, it’s your best bet by a long shot. The only bummer is that on the morning of the 5th, there’s light rain, but that’s a small price to pay for the best waves of the window.

The days after that drop off again. Thursday the 6th of August has a smaller 5ft swell with a clean cross-off breeze, but the energy is a moderate 488. It’s surfable, but nothin’ special.

So, if you’re lookin’ to get wet, your best shot is the morning of Wednesday the 5th of August. Everything else is either too small, too windy, or just plain messy. The first week is a struggle, but that one day in the second week is worth waitin’ for. Keep an eye on the forecast, but for now, that’s the call.

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.
