The Lowdown

Alright, Rusty here. Let’s talk Renaca.

Right now, things are pretty flat and ordinary. Monday morning the 24th of August is showing a tiny 2ft SSW swell with a 13-second period, but the wind is an inconsistent light offshore from the NNE. It’s surfable, but very ordinary. The water temp is about average for this time of year, nothing unusual.

Monday afternoon it gets messy with light onshore wind and poor conditions. Tuesday the 25th stays small, but the afternoon has a 3ft to 3ft WSW swell and a 14-second period with clean, cross-offshore wind – that’s a little window of fun, clean surf, but still small.

We hit a wall from Wednesday the 26th into Thursday the 27th. The swell jumps to 5ft and then 11ft to 12ft, but it’s coming with strong cross-onshore wind, making it a messy, blown-out mess. The 11ft to 12ft swell on Thursday is way too big for this break, combined energy is a massive 5149, and it’s not a good look for anyone. This is more of a kite surfing setup than a paddle surf one.

The first real standout hits Friday morning the 28th of August. We get an 8ft WSW groundswell with a 13-second period, and the wind goes glassy. Absolutely clean. Combined energy is 2353 – strong, powerful swell. This is solid, expert-level surf. It’s a bit big for beginners, but for experienced surfers, it’s excellent.

Saturday morning the 29th is almost as good: 8ft to 8ft WSW swell, glassy again, combined energy of 1626. Another excellent morning for experienced crew.

The first week of September is a mixed bag. We get a long gap of marginal conditions with onshore winds and messy chop. Tuesday the 1st is poor, and the swell stays funky.

The next true standout is Saturday morning the 5th of September. Glassy conditions, calm wind, and a 6ft to 6ft WSW swell with a 13-second period. Combined energy is 983 – moderate, but the glassy wind will make it clean as a whistle. This one is for the intermediate-to-advanced surfer, very good conditions.

Then we roll into Monday the 7th of September. That morning has a 6ft SW swell with a 10-second period and cross-offshore wind from the NNW. The afternoon is similar with a 6ft to 7ft SW swell. Both sessions are clean and have that “very good” feel.

Tuesday the 8th of September wraps it up with a glassy 5ft SW swell. The period is short at 8 seconds, but the glassy wind makes it a fun, clean morning for the experienced surfer. Combined energy is 783 – moderate energy.

For the second week, it’s all about that glassy Saturday the 5th and the clean Monday/Tuesday the 7th and 8th. The first week’s Friday the 28th is the big standout for power and size for experts. Heads up: crowds are possible at Renaca, especially on those good days.

Rusty.

Information about the Renaca Surf forecast

The above surf forecast table for Renaca provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Renaca can be found by selecting the local surf guide option on the grey menu. Our Renaca 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 (Renaca) 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 Renaca 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.

Renaca is 11 km (7 miles) from the city of Vina del Mar. If you plan a holiday in Santiago, look for hotels and other accommodation in Vina del Mar. Vina del Mar has rooms for a wide range of budgets as well as car hire and transport links.
