The Lowdown

Alright folks, Rusty here. Let’s talk about what’s on the table for the next couple of weeks. The surf window is open from Monday the 7th onward, but don’t expect a straight run of perfection. We’ve got some solid groundswell pulses lining up, but the wind is going to be the real gatekeeper.

The Overall Pattern
We start Monday morning the 7th with a 5 ft SW swell at 13 seconds, giving us a moderate wave energy (694). Water temp is sitting at 58°, which is a touch warmer than normal for this time of year. So you can leave the thick rubber at home. But Monday is a write-off—cross-shore wind, marginal conditions. Tuesday the 8th is your standout early in the forecast. That morning we see a glassy surface, 4 ft SW groundswell at 13 seconds (613 moderate energy). That’s the session to aim for. Clean, lined up, and manageable for experienced surfers. Beginners should be fine too, it’s not too big.

After Tuesday, things get sloppy. Wednesday the 9th is a mess—onshore wind and weak energy (345). Thursday and Friday mornings offer a brief clean-up with cross-off winds on Friday morning the 11th, but the swell is down to 3 ft (294 energy). Not terrible, but not the highlight.

The Next Real Window
The bigger stuff shows up around Sunday the 13th. Sunday morning brings a 5 ft SW swell at 9 seconds—short period, but the combined energy is moderate (559) and we get clean, cross-off winds. That’s a good call for the advanced crew. But watch out—Sunday afternoon gets blown out.

Then we have a notable pulse on Monday the 14th morning: 4 ft SW swell with a very long 15-second period, pushing the combined energy up to 986. That’s moderate-to-strong energy. This groundswell will have long, waiting sets. It’s going to shape up nicely at points and reefs, but at a beach break like Renaca, the long period might make waves wall up a bit. Still, with light cross-on winds, it’s a solid session for experienced surfers.

The Second Week Warning
Tuesday the 15th afternoon is a nope—7 ft SW crashing in with 30 km/h (19 mph) onshore wind. That’s only for the kamikazes. Wednesday the 16th morning is better, with 6 ft SW at 10 seconds (693 energy) and light cross-on wind, but it’s still a big, raw swell. Be picky about the tide.

By the 21st and 22nd, we’re hanging on scraps. The 22nd afternoon is interesting—a late-breaking change: 5 ft SW at 10 seconds (958 energy) with offshore wind from the NE. That’s clean. But it’s the 22nd. Keep your eye on that one, but it’s a long way off, so take it with a grain of salt.

Best Bet
Without a doubt, Tuesday morning the 8th of September is the pick of the first week: glassy, 4 ft clean SW groundswell, moderate energy, and a break that handles it fine. Not too crowded yet. If you can wait, Sunday morning the 13th and Monday morning the 14th are also good for the more advanced crew, but the wind will be your deciding factor.

Remember, Renaca is consistent, so even if the runs look quiet, it won’t stay flat for long. For now, get on it Tuesday morning.

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.
