The Lowdown

G’day, Rusty here, and I’ve got a look at what’s coming up for Renaca over the next couple of weeks. First thing you need to know – this is a break for the experienced crew only. It’s an advanced, exposed setup that loves a good SW groundswell, but when it gets big, it gets real. No place for beginners.

The forecast kicks off with a bang. Tuesday morning, July 14, is a full-on standout. We’re talking a solid 9.8ft swell from the WSW, with a 13-second period pushing a massive 2723 (moderate to strong wave energy) into the beach. The wind is light and offshore from the NNE at 3 mph, keeping things clean. Conditions are prime for the seasoned surfer, but this is well over 8.2ft – experts only, and you’ll need to be on your game. The water temp is about average for this time of year, so no surprises there.

Tuesday afternoon eases slightly to 8.2ft, still from the WSW, with a cross-off breeze from the north at 3 mph. It’s clean and still a good option for the experienced, but the morning was the real peak.

Wednesday, July 15, drops off. The swell fades to 4.6ft in the morning with a cross-shore wind from the WNW at 9 mph, and the energy drops to 771 (moderate). It’s a marginal session with some chop. Afternoon improves a touch – 3.9ft from the W, 10-second period, and a light cross-off breeze from the NNW at 6 mph. Clean, but nothing to get excited about. The combined energy (479) is still moderate.

Thursday, July 16, is a write-off. The morning has a 4.3ft windswell from the WNW with a short 7-second period – weak and messy. The wind is strong at 9 mph and the energy is low (327). By afternoon, it’s tiny (1.3ft) with a 17-second period, but the wind is howling at 28 mph and the whole thing is a mess. The energy (178) is weak. Hard pass.

We hit a gap of a few days with no real recommendations. Friday, July 17, through to Sunday, July 19, all show poor surf conditions, with rain and strong winds. The swell is small to moderate, but the wind is just too strong and the rain heavy. Not worth paddling out.

Monday, July 20, brings another big pulse. Morning sees a 9.8ft SW groundswell, 11-second period, and a light offshore from the ENE at 6 mph. The energy (2427) is strong, but it’s too big for this break – the finder says it’s predicted to be too big. Afternoon is a better call: 7.5ft from the SW, 10-second period, with glassy conditions as the wind drops to 3 mph from the north. The energy (1793) is strong, and the clean, glassy surface makes it a solid option for the experienced. Crowds are “sometimes” an issue here, so you might have some company, but it’s worth it.

Tuesday, July 21, serves up a nice little session. Morning has 3.9ft from the W, 11-second period, with a gentle offshore from the NNE at 9 mph. The energy (572) is moderate, and the waves are clean and workable. Afternoon is even better for the soul: 3.6ft, same direction, with a dead calm 0 mph wind and glassy conditions. Pure magic. The energy (499) is moderate.

From Wednesday, July 22, through to Thursday, July 23, it’s small. Swell drops to 2.3ft to 3.3ft, with glassy or clean conditions, but the energy is weak (139 to 262). Surfable for a longboard, but nothing to write home about.

Friday, July 24, picks up a bit. The morning has 6.2ft from the WSW, 10-second period, with a light cross-shore from the SSE at 3 mph. The energy (793) is moderate, but there’s a bit of chop. Afternoon is 5.6ft, same direction, but with onshore wind from the SW. The tide might be tricky – it’s marginal.

Saturday, July 25, is a dud with rain and strong winds. Poor conditions.

Sunday, July 26, brings a big pulse again. Morning and afternoon both have 8.2ft from the WSW, 13-second period, with strong energy (2002 to 2197). The wind is cross-off or light cross-shore, keeping it clean. This is expert territory again – over 8.2ft – but it’s a solid option for the skilled. The long period (13 seconds) means it’s a groundswell, so it’ll have

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.
