The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the menu for the next couple of weeks.
First up, we're talking about Bikini, an advanced spot that's a mix of beach and point. The water's sitting at 51°, which is about average for this time of year, so nothing to write home about there. The swell energy is moderate, but we're in for a bit of a wait before the real fun starts.
The first few days are a write-off, I'm not gonna lie. Saturday the 22nd through Sunday the 23rd is a mess with strong cross-onshore winds and a big, raw swell. The energy is massive – we're talking (2,209) on Sunday morning and a whopping (5,329) on Sunday afternoon – but it's all blown out and messy. That's an expert-only situation if it's even surfable, and honestly, it looks more like a kite-surfing day than a paddle-surfing day.
Monday the 24th is still pretty average with light cross-onshore winds, keeping the waves small and bumpy. The energy is moderate (834).
Then we see the window open. Tuesday morning the 25th is the real standout. The wind swings offshore from the NE at 6 mph, which is exactly what we want. The swell is 4ft from the SSE, and with a period of 11 seconds, it's got some decent groundswell energy (414). The conditions are clean. This is the best session on offer, no doubt about it. The size is manageable for a solid intermediate, but it's an advanced spot, so you'll want your wits about you.
The next few days are promising. Wednesday the 26th and Thursday the 27th are also looking good with gentle offshore winds and clean conditions. The swell is a bit smaller, dropping from 5ft to 3ft, and the energy backs off a touch (671 to 238). By Thursday afternoon, we even get a glassy moment with a 2ft SE swell. That's a nice little window.
But then, from Friday the 28th onward, it all fades out. The swell drops off to knee-high dribble, the energy is weak (under 100), and we get a long dry spell of poor surf. The wind is either onshore or cross-shore, and it just doesn't look good. There's a brief, tiny whisper of life on Friday the 4th of September with some clean but small 2ft waves, but that's about it. The rest of the run into the second week is flat and not worth getting wet for.
So, to wrap it up: Tuesday the 25th is your one clear shot for a proper session with clean, offshore winds and a good 4ft of S swell. After that, it's a waiting game until maybe the 4th of September, but don't hold your breath.
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.
