Table - best surf conditions forecast for Bikini over the next 16 days.
G'day, it's Rusty here.
Alright, we've got a 16-day window for Bikini, and it's a bit of a slow burn. The first few days are pretty average, with small, mixed-up swells and cross-shore winds making for messy conditions. There's a noticeable gap at the start where the surf isn't worth paddling out for.
By Thursday the 10th, the energy starts to build, with a combined swell energy of 249 (moderate), but the swell is still small and the wind is almost side-offshore, so it's just clean but weak. Saturday the 11th afternoon sees the best early window. The swell holds at 3ft from the ESE with a 14-second period, and the combined energy is 505 (moderate), which is the strongest we've seen yet. The wind is cross-offshore, so it's clean, but the long period might make it a little flat and walled-up at the beach – Bikini is a beach and point setup, so that longer-period groundswell could actually work well on the point.
Monday the 20th is where it starts to get interesting. Monday afternoon brings a 5ft easterly swell with a moderate offshore wind from the NNE. The combined energy jumps to 375, and conditions are described as sounding pretty good for surf. This is the standout of the run, but it's 13 days away, so treat it as promising but not a lock. By Tuesday the 21st, the wind swings light and cross-offshore, and the swell is still a solid 4ft from the east with decent energy (260).
For the real highlight, point your board at Bikini for Monday afternoon the 20th. That 5ft easterly swell with moderate offshore winds (NNE) should offer the cleanest, most powerful waves of the outlook. Keep in mind the combined swell energy is 375, and with the wind offshore, it should be smooth. The water temperature anomaly is -0.9°, meaning it's a touch cooler than average for this time of year, but nothing out of the ordinary.
If you're just looking for something to get wet, the clean but tiny windows around Thursday the 10th and Saturday the 11th are options, but you'll be scratching for waves. After the 20th, the swell fades, and conditions get messy again through the end of the period.
That's the story, mates. Keep your eyes on the 20th and hope the forecast holds. 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.
