The Lowdown
Alright folks, Rusty here. Let’s get into it.
We’ve got a solid run of surf coming up at Renaca, starting Monday the 27th of July. The water is sitting at 56°F, which is about normal for this time of year, so no nasty surprises there.
Monday morning kicks off with a clean 5ft swell from the west, with a nice 10-second period. The wind is a light cross-offshore, so the waves will be holding up well. Combined wave energy is moderate at 910. This is a solid, fun size for experienced surfers.
Monday afternoon steps it up: 6ft from the west, period stretching to 12 seconds, and the energy jumps to 1631. The wind stays light and cross-off. This is excellent, proper surf. Tuesday morning is even better – 8ft swell from the west-southwest, 12-second period, and a massive 1599 energy reading. The wind is a light cross-off again. This is the standout session of the week for strong, experienced surfers. Tuesday afternoon goes glassy as the wind drops to nothing, with a 7ft west-southwest swell. The conditions will be pristine.
Wednesday morning the 29th is glassy calm with a 4ft west swell, but the energy drops to 551. It’s still very clean, but smaller. The best of the best is Tuesday morning.
After Wednesday afternoon, the quality drops. Thursday and Friday see some bigger swells, but the wind gets messy. Friday morning the 31st has a 7ft west swell, but a moderate cross-shore wind chops it up. Friday afternoon, however, the wind goes glassy again with a 6ft swell – that’s a sneaky good session.
The first weekend of August is small and glassy. Saturday the 1st has 4ft south-west swells with glassy conditions all day – perfect for a longboard or a fun log. Energy is moderate at 853. Sunday the 2nd is smaller, around 3ft to 3ft.
There’s a gap of smaller stuff early in the week, then Monday the 3rd of August sees a return of clean, glassy surf with a 5ft to 6ft west swell. A good session.
Tuesday the 4th of August is a serious standout for the experts. The morning brings a 5ft west-southwest swell with a very long 14-second period, and the energy is solid at 1281. The wind is light and glassy. This is a groundswell that will really line up at Renaca’s point. However, the afternoon goes onshore, so hit it early.
From Wednesday the 5th through Sunday the 9th of August, the swell gets big. Too big. We’re looking at 8ft to 12ft. The wind is mostly onshore or cross-onshore, and the energy readings are huge (over 4000 on some days). This is not paddle-surfing territory. It’s better suited for the tow crew or the kite surfers. The forecast says it’s just too big for the break.
The swell continues to pump into the second week, with Tuesday the 11th of August showing a massive 12ft south-west swell with a 14-second period, completely glassy. The energy is 3901. Again, this is enormous and only for the most experienced big-wave chargers, if anyone. It’s a promising but very heavy forecast.
So, the best call for the average surfer is Tuesday the 28th of July, morning session. For the experts, Tuesday the 4th of August morning is a real standout for clean, powerful groundswell.
Rusty out.

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.
