The Lowdown
Alright, let’s get into it. This is Rusty, and I’m looking at the forecast for Bikini. We’ve got a stretch ahead that’s gonna test your patience, but let’s break it down.
First thing: water temp is sitting at 55°, which is a touch warmer than normal for this time of year. That’s a nice little bonus when you’re paddling out.
The outlook kicks off on Wednesday the 2nd of September. The morning shows a little bit of life: 2ft of easterly swell with a 9-second period, and the wind is a gentle offshore from the north. It’s surfable, but it’s very ordinary. Wave energy is weak (57). That’s about as small as it gets. The afternoon goes south quick with a cross-offshore wind and a score of zero. Not worth paddling out for.
Thursday the 3rd is a write-off. The swell bumps up to 3ft from the east with a longer 11-second period, and the energy jumps to moderate (202), but the wind is a messy cross-onshore westerly at 16 mph. It’s choppy and poor. Thursday afternoon is the same story.
Friday the 4th keeps the poor run going. Swell shifts to the SSW at 4ft, but it’s short-period windswell at 7 seconds. Onshore wind from the southwest. The energy is moderate (154), but it’s just ugly. Afternoon gets a direct onshore wind. No good.
Saturday the 5th is flat and weak. Swell drops to 2ft from the south, 7-second period, weak energy (51). Light cross-onshore wind. Not a wave worth chasing.
Sunday the 6th brings a pulse of size: 7ft from the south, but it’s still short-period at 7 seconds. The energy is strong (401). However, the wind is a cross-onshore southerly at 16 mph, and there are rain showers. It’s choppy and messy. That’s big, but it’s not clean. This is only for the experienced, and even then, the wind is a fight.
Monday the 7th offers a slight improvement: 5ft from the SSE with a 9-second period, and the energy is still strong (394). The wind is light cross-onshore in the morning. It’s listed as marginal. The afternoon cleans up a bit with a cross-shore wind, but the swell drops to 5ft. Still not a standout.
Tuesday the 8th sees a drop in swell to 3ft from the SE, 8-second period, moderate energy (148). The wind goes offshore from the northeast in the morning. It’s clean, but the waves are tiny. Surfable but ordinary.
From Wednesday the 9th through to the end of the second week, it’s a long stretch of small, weak, or wind-affected surf. The swell rarely breaks 3ft, and the energy is mostly weak to moderate. There are a few mornings with offshore or cross-offshore winds (like the 9th, 16th, and 17th of September), but the swell is too small to get excited about. The 12th of September has a 2ft swell from the east with a very long 13-second period, but the wind is a direct onshore southerly at 13 mph, making it a washout.
The 15th of September shows a bit more size: 4ft to 4ft from the east, with moderate to strong energy (253 and 339), and cross-offshore winds. But the period is only 8-9 seconds, and the wind is strong at 16-19 mph. It’s clean, but the quality is missing.
The standout: Honestly, there’s no true standout session in this entire 16-day window. The best you’re going to get is the morning of Tuesday the 8th of September, with a clean 3ft easterly swell and a gentle offshore wind. It’s small, but it’s the cleanest wave in the whole forecast. If you’re desperate, that’s your window.
Crowds: Bikini is often crowded, so even on these small, ordinary days, you won’t be alone.
Consistency: The break is very consistent, but the quality is not. This is a tough run. For a spot that usually pumps, this is a frustrating stretch of small, wind-affected, or just plain messy conditions. The setup is a beach and point, so when the swell is significant and the wind is poor, it’s more interesting for kite surfing than paddle surfing.
Keep an eye on the forecasts, because it tends not to stay this poor for long. But for now, don’t rush.
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.
