The Lowdown

G’day, Rusty here. Look, I’ll be straight with you – the surf outlook for the next two weeks at Bikini (beach and point) is a real mixed bag and, honestly, pretty frustrating for the most part. We’re staring down a long stretch of ordinary to poor conditions that’ll test your patience. The water’s sitting at 52°F, which is just about average for this time of year, so no surprises there.

The first real window of hope doesn’t arrive until July 25th. That Saturday morning, the breeze swings light from the ENE, giving us a clean cross-off wind. The swell is a solid 4ft out of the SSE, with a period of 11 seconds – a nice groundswell pulse. The combined energy is a moderate 327, and it’s pulling in from the south, which is off the optimum for Bikini, but that clean surface and waist-to-chest high sets will make it worthwhile. The crowd factor is often an issue here, so be ready for company. July 27th, Monday morning, is another promising call. It’s a 4ft E swell with a moderate offshore breeze from the NE, combining energy at 224. The wind is offshore, so it’ll be clean, but the swell direction is a bit east for the optimum south. Still, a solid shoulder-high option.

The rest of the forecast is tough. From July 16th through the 24th, we’re looking at mostly poor surf with onshore or cross-onshore winds, combined with weak energy (mostly under 200) and short-period slop. The 21st and 22nd see some bigger, messy swell (6ft to 7ft) but with onshore wind and short periods, it’s a chop-fest, frankly more interesting for kite surfing than paddling. There’s a gap of nearly a week where I wouldn’t bother. July 29th shows a bigger 7ft to 7ft S swell with lots of energy (up to 1041), but the wind is cross-shore and the period is short, so it’s a marginal, lumpy affair for experienced surfers only.

The standout is the 25th Saturday morning – that’s your best bet for a fun, clean surf. The 27th Monday morning is a solid backup. Everything else is a waiting game.

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.
