Table - best surf conditions forecast for Renaca over the next 16 days.
Alright, Rusty here. Let’s talk about Renaca. We’ve got a solid run of big, powerful swell coming, but this is strictly for the advanced guys. The water is a bit colder than average for this time of year at 54°F, so suit up.
The main event kicks off on Monday, July 13th. The morning is absolutely perfect with glassy conditions and a clean 6ft swell from the WSW at a very long 18 seconds. The energy is pumping (2560), and it’s excellent surf for experienced surfers. The afternoon builds even more, hitting 8ft from the WSW with a 16-second period and that same glassy finish. This is the best on offer – big, clean, and lined up.
Tuesday, July 14th, sees the swell peak in the morning at 10ft from the WSW, and while the wind is a light cross-offshore keeping it clean, that size is strictly for the experts. The energy is huge (2832). The afternoon drops back to 8ft with the same cross-off breeze, still a heavy session. Wednesday the 15th is a step down to a more manageable 6ft from the WSW, but the energy drops to moderate (815). Conditions are still clean with a cross-off wind.
There’s a noticeable drop in quality from Thursday the 16th through the weekend. The swell gets messy with a short-period NW windswell and strong winds. Thursday afternoon sees a near gale from the N at 34 mph, writing it off. Friday the 17th offers another big pulse of 12ft from the NW (2746 energy) with a light offshore wind, but again, that’s big and heavy with heavy rain. It’s a bomb for experts only.
The following week is a mixed bag of smaller, less consistent swell. There’s a nice little window on Sunday, July 19th, with a glassy morning and a 4ft W swell (776 energy), perfect for a longboard. The 22nd of July has a late afternoon pulse of 7ft from the SW with a 12-second period and a moderate offshore wind, offering another clean session for the advanced crew. The final week into July 27th and 28th serves up some glassy mornings with waist-to-chest high WSW swell (4ft to 5ft) and a long period, a solid way to wrap up the 16-day window.
In short, the first four days are the real deal for the experienced crew. After that, pick the clean, glassy mornings for the fun stuff.
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.
