Alright, Rusty here, and let me break down the next 16 days for the region. There’s a quiet start, but buckle up for a wild one.
For the first few days, it’s flat and small. A 0.3ft swell with weak energy (10) means the board stays in the truck. The wait is on. Things fire up on Monday the 14th.
The highlight is a massive pulse arriving Monday morning the 14th at Renaca. That’s a 10ft swell out of the WSW with a 13-second period and huge energy (2904). It’s too big for beginners, but if you’re advanced, the Tuesday afternoon the 14th with clean 8ft faces and offshore wind is the session to circle. The water is a bit colder than usual for the season at 54°.
Tuesday morning the 15th settles to a cleaner 5ft swell with an 11-second period, cross-off wind, and moderate energy (679). It’s a solid, user-friendly option. The week stays active, but the real monsters are Monday the 20th and Monday the 21st.
Monday the 20th is a brute – a 13ft swell from the WNW with energy screaming at 3016 in the morning, and 4535 in the afternoon. That is expert-only. The wind is offshore or cross-off, cleaning it up, but you need to be on your game. Tuesday the 21st morning offers a glassy 6ft swell from the SW (908 energy). That’s the cleanest, most accessible window in the whole run.
After that, the swell sticks around 7ft to 8ft for most of the next week, but the wind turns messy. The last few days (Friday 25th and Saturday 26th) drop off in size and quality, fading to weak and marginal. Don’t worry about a few flat days here – it’s normal for this spot. Forecasts can change. There’s plenty to aim for.
Stay sharp. The big ones aren’t for everyone.
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.
