The Lowdown

Alright folks, let's talk Bikini. The next couple of weeks are a story of two halves: a long, flat, frustrating start, and then a real solid punch of swell that's worth waiting for. You're going to have to be a bit choosy.

The first week is a dud. From Wednesday the 22nd through the end of July, it's mostly tiny, weak surf with messy wind. The combined swell energy is mostly under 100 (94, 97, 69) – that's weak energy, and the period is short, around 6-8 seconds. It's just wind-chop. Thursday the 23rd morning offers a brief moment of clean, cross-off wind with a tiny 3 ft SSE swell, but it's barely worth waxing up. The water temperature is 53°F which is about average for the time of year, so you won't need a super thick suit.

The first real stand-out arrives on Saturday, August 1st. The morning brings a clean 5 ft swell from the E with a light cross-off breeze, and the combined energy jumps to 349 (moderate). The afternoon is where it gets special. We're looking at glassy, flat-calm conditions and a 5 ft ESE swell. For a spot like Bikini, a beach and point setup that's very consistent and exposed to S swells, this is a rare gem. The swell direction is from the ESE, which lines up well. Expect good, clean waves. It’s not huge, so it's manageable for most.

The following Monday, August 3rd, sees a bump in size with a 7 ft SE swell, but the wind is onshore or cross-onshore, and the conditions are marginal. The energy is strong (over 600), but the wind is going to make it a messy, choppy mess.

The absolute best of the bunch is on Tuesday, August 4th. This is the one to circle on your calendar. We've got a 7 ft ESE swell with a period of 10 seconds, and the wind is a clean cross-off from the north. The combined swell energy is 778 – that's strong to very strong wave energy. The morning is looking clean, and the afternoon goes glassy. For a spot like Bikini, which is a point and beach break, a long-period ESE swell like this should set up really nicely. With that size, it's on the bigger side, so this one is best left for the experienced crew. Beginners, sit this one out.

The wave quality stays decent through Wednesday morning the 5th, with a 5 ft ESE swell and light cross-shore wind, but the wind swings onshore in the afternoon. By Thursday the 6th, the swell drops back to 3 ft, but it’s clean with offshore wind and a long 11-second period, making for some nice, glassy leftovers. A good fallback option. Long-period groundswell, so expect longer lulls between sets.

Summary: The first 9 days are a write-off. Don't bother until August 1st. The best surf of the forecast is squarely on Tuesday, August 4th with a solid, powerful ESE swell, offshore wind, and clean conditions. Saturday August 1st afternoon is also a great, smaller alternative. The window from August 1st to the 6th is where you want to be in the water. After that, it fades.

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.
