The Lowdown
Alright, surfers, Rusty here. Let's take a good, hard look at what Bikini has in store for us. It's a bit of a mixed bag, so strap in.
First off, the water temp is sitting at 53°, which is about normal for this time of year. Not a shock to the system, but you'll still want a good wetsuit.
The story for the next couple of weeks is pretty grim for the most part. We're looking at a long dry spell. From now through the end of July, the surf is small, weak, and the wind is just never on our side. For days on end, we're looking at cross-onshore and choppy conditions, with swell heights barely cracking 3 feet. The wave energy is weak, mostly under 200 (moderate energy at best, but poor quality), and it's just not worth paddling out for anything of real quality. The wind is a constant problem, with most of the period seeing a moderate breeze from the south or southeast, chopping everything up.
The first real glimmer of hope doesn't arrive until the very start of August. The standout window is the morning of Saturday, August 1st. We've got a clean, light offshore breeze, and the swell is starting to show some life. A 3-foot swell from the southeast with a long period of 14 seconds is pushing in, giving a combined energy of 323 (moderate). That's a proper groundswell, and while the size is small, it's got the shape and power to make it fun. The break is a beach and point setup, and with a long period, the point will be the call for a better wave shape. Be aware that crowds are often a factor here.
The other session to keep an eye on is the morning of Sunday, August 2nd. The swell has dropped a touch to 3 feet, still from the ESE with a long 13-second period, and the wind is forecast to be glassy. That's absolute perfection for the small stuff. The energy is still solid at 220 (moderate). This is the kind of morning where you can get some clean, long rides if you're in the right spot.
For the rest of the first week of August, the energy drops back down, and the wind changes, so it's back to being ordinary. The 1st and 2nd are the only real standouts in this whole 16-day window.
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.
