The Lowdown

Alright, let’s break it down. Mick here, and I’m looking at this stretch of days for Bikini (Bikini). It’s a real mixed bag, and I gotta be honest – for a lot of this period, we’re looking at small, messy, or just plain ugly conditions. There’s a decent window of solid surf in the first week of August, but patience is the name of the game.

The first recommendation starts on Sunday, July 26th, and it’s a flat start. We’re talking tiny, weak swell with rippled bump. The wind is cross-on and the wave energy is barely a whisper (93). It’s not the kind of thing that gets a local out of bed. This run of poor surf stretches through the next several days. The swell stays under 3 ft, the period is short and messy, and the wind just won’t cooperate. The water temp is about average for the time of year, no weird anomalies to report.

We get a quick, hopeful moment on Thursday, July 30th morning. The wind goes glassy, which is a major positive, with a little 2 ft S swell (94 energy). That’s a surfable, clean little wave, but it’s tiny. It’s the kind of dawn patrol that’s nice for a longboard, but not a standout.

The real action kicks off on Monday, August 3rd. The morning shows 6 ft of E swell with a short period (7 seconds) but it’s clean under offshore NNE winds. The energy is moderate (326). The afternoon is where it gets serious: 7 ft E swell, period 8 seconds, and moderate offshore winds. The energy jumps to a powerful 931. This is a standout window. This is a solid, punchy, clean wave, but at 7 ft, it’s pushing into expert territory – it’ll be too big for beginners. With the swell coming from the east, it’s hitting the optimum direction for this spot. Crowds are likely here, as it’s often busy.

Tuesday, August 4th morning carries that energy through with a 6 ft E swell, period 9 seconds, and light cross-offshore NNW winds (786 energy). This is another top-tier session. The waves will have better shape with that longer period, though it may get a bit straight-breaking at the beach sections. The afternoon sees the wind switch to a strong cross-onshore, turning it lumpy. So hit the early session.

After that, the quality drops hard. The rest of the 16-day window is a write-off – small, onshore, or just poor surf. There’s a long gap of nothing much from the 5th to the 10th. The last few days are all small, weak, and messy.

So, to sum it up: the best bet is the morning of Monday, August 3rd and Tuesday, August 4th morning. If you can handle a solid 7 ft wave with offshore wind, Monday afternoon is the true standout. The rest of the period is a write-off, so don’t hold your breath.

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.
