The Lowdown
Alright, Rusty here. Let’s break down what’s coming over the next couple of weeks.
The water temp is sitting at 57°F, which is about 1°F warmer than the long-term average for this time of year – nothing crazy, just a mild anomaly.
The first chance to get wet is Monday morning, August 17th. Ritoque is showing a 3ft WSW swell with a 14-second period, and the combined wave energy is a moderate 572. Wind is light out of the south at 5 km/h, cross-off, so the surface is clean. Not a bad start, but the real standout is Wednesday the 19th. That morning, a 6ft SW groundswell with a 15-second period arrives, and the energy jumps to a strong 1869. The wind is glassy from the NW at 5 km/h. This is a session for the experienced crew – the long period will give it real power, but at a beach break, those long gaps between sets might make it tricky. The afternoon stays glassy with a 6ft WSW swell.
After that, it gets messy. Thursday the 20th and Friday the 21st bring stronger winds and cross-onshore conditions, making the surf choppy. The swell hits 7ft on Friday, but with a period dropping to 7 or 8 seconds, it’s weak and disorganised. We’ve got a dry spell through the weekend, with only marginal conditions. The waves are small and the wind isn’t cooperating.
Looking into the second week, there’s a promising window building. Monday the 24th of August has a clean, glassy start with a 4ft WSW swell and a 12-second period, energy at 471. The afternoon stays glassy and clean. But the real highlight is Wednesday the 27th of August. The morning is glassy, but the afternoon is where it’s at: a 3ft WSW swell with an 18-second period, energy climbing to 1114. That’s a very long-period groundswell, and with glassy conditions, it’s going to be a clean, punchy wave – best for those with experience. Then Saturday the 29th of August morning brings a solid 7ft WSW swell, glassy winds, and strong energy of 1501. That one’s for the experts.
Overall, the best surf is on Wednesday the 19th, and then again on Wednesday the 27th and Saturday the 29th of August. The long-range ones are promising but less certain.
Rusty.

Information about the Ritoque Surf forecast
The above surf forecast table for Ritoque provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Ritoque can be found by selecting the local surf guide option on the grey menu. Our Ritoque 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 (Ritoque) 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 Ritoque 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.
Ritoque is 6 km (4 miles) from the city of Quintero. If you plan a holiday in Santiago, look for hotels and other accommodation in Quintero. Quintero has rooms for a wide range of budgets as well as car hire and transport links.
