Table - best surf conditions forecast for Renaca over the next 16 days.


The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s shaking on the coast.

We’re looking at a stretch that starts slow, real slow. For the first week and a half, the surf is pretty marginal. The conditions are constantly fighting us – mostly cross-on or onshore winds and choppy, messy waves. There’s a real gap from the 7th of September right through until the 11th, where nothing is really worth paddling out for. The combined energy of the swells is weak to moderate at best, sitting around 376 to 791 (moderate wave energy), but the quality just isn’t there.

Renaca is the only spot on the table, an exposed beach break that is very consistent. The wave heights are hovering around 3 ft to 5 ft, coming from the SW. The water temp is about average for the time of year, nothing to write home about. The real issue is the wind – it’s cross-on or onshore for the majority of the time, turning the waves into a bumpy mess.

Now, there is a glimmer. On Friday morning, the 11th of September, we get a glassy window. The wind goes completely calm, the swell is a clean 3 ft from the SW, and the combined energy is a weak 295. It’s small, but it will be the cleanest surf of the early week. The score is low, but it’s the only real chance for a longboard or a fun board to get some smooth, clean lines. The rest of the week falls back into the same old pattern of poor conditions.

The Standout

Alright, if you've got patience, this is the one. Skip ahead to Sunday, the 20th of September. The morning is glassy, with a clean 6 ft swell from the SW. The combined energy jumps to 1095, which is strong wave energy. This is where it gets good for experienced surfers. The real magic is the afternoon. The wind is glassy again, from the NW, and the swell pushes to 8 ft from the SW with a period of 14 seconds. That’s a solid groundswell. The combined energy hits a massive 2165, which is very strong wave energy. This is going to be powerful, clean, and lined up. It’s too big for beginners, but for the crew who know what they’re doing, it’s the best on offer. The only downside is that it’s a beach break, so a long period swell like this (over 11 seconds) might break a bit straight, but the glassy conditions will make it a memorable session.

The 22nd of September, Tuesday morning, sees a huge 8 ft SW swell (over 15 seconds period) with a combined energy of 2863 (very strong wave energy). This is big, powerful, and for experts only. The wind is onshore, though, which will likely put a heavy chop on the face. It’s a powerful wave, but it won’t be clean.

So, if you’re hanging for a wave, the 20th of September is the standout. The 11th is your only other hope for a clean, small wave.

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.
