The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the menu for Bikini over the next couple of weeks.
Straight up, I’m not gonna sugarcoat it – the forecast is a tough one. We’ve got a big gap of near-zero surf to start. For the first week, there’s nothing really worth paddling out for. The pattern is dominated by weak, short-period windswell and messy cross-onshore winds. It’s going to be a quiet, frustrating few days on the beach.
The first possible glimmer comes on Thursday 23rd July. The morning brings a tiny 3ft swell from the ESE with a light breeze, and the conditions are clean. But at 7 seconds period, it’s weak and the combined swell energy is only 119 – that’s barely a ripple. It’s surfable for a longboard if you’re desperate, but it’s far from good.
The pattern stays flat and weak right through until the end of July. You’ll see a few pulses of energy, like on Friday 25th July with a combined energy of 242 from a 12-second S swell, but the wind is cross-on and the height is only 2ft. Not enough to get excited about. Saturday 26th and Sunday 27th offer clean, offshore winds in the mornings, but again, the swell is tiny – 2ft to 3ft – and the energy is low.
The real standout, and the only one worth marking on your calendar, is Tuesday 4th August. Now, this is a long way out, so treat it as promising but not locked in. The morning of the 4th shows a 4ft swell from the S, but with a very long period of 15 seconds. That’s groundswell, and it’s packing a combined energy of 914 – that’s serious juice. The wind is cross-off and clean. The catch? This is a beach and point set-up, and a 15-second period groundswell can break a bit too straight on a beach. It’s more of a point or reef wave, but Bikini has a point, so it could line up nicely for the advanced crew. The afternoon picks up to 6ft from the ESE with a shorter 8-second period, but a still strong 602 energy reading. The wind stays clean. This is the only day that looks genuinely good.
Bottom line: The first week and a half is a write-off. You’re looking at mostly flat, weak, or wind-affected conditions. The one true highlight is the 4th of August. The water temperature is sitting at 53°F, which is about 1°F warmer than normal for this time of year – nothing unusual, just a touch on the mild side for Bikini.
Rusty out.

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.
