The Lowdown
Alright folks, Rusty here with a look at what the next couple of weeks have in store for us at one spot.
We’ve got a bit of a slow start, but then it picks up. The first real action worth paddling out for kicks off on Wednesday morning, July 15th, and it’s a beauty of a window. The standout session is hands down Wednesday morning. The ocean is glassy with 0 mph wind, 4 ft of clean, 13-second SW groundswell. The water is sitting at a comfortable 62°, which is bang on average for this time of year. The energy in the water is a solid moderate at 306. It’s going to be clean, lined up, and just a pleasure. That morning is the best on offer in the entire run.
After that, the quality drops off with some cross-onshore winds and marginal conditions through Thursday and Friday. Friday afternoon, July 17th, sees the wind go glassy again with 4 ft of WSW swell at 11 seconds and moderate energy. It’s surfable, but not a patch on Wednesday. Saturday (July 18th) and Sunday (19th) are similar stories – surfable but with those light cross-onshore breezes messing with the face.
We then hit a rough patch from Sunday the 19th afternoon right through the end of the following week. Most of Monday the 20th through to Wednesday the 22nd of July is a write-off for clean paddling. The wind gets up, the quality drops, and even though the swell is around, the conditions are messy. On the 23rd of July (Thursday), we see a proper pulse of energy building. The afternoon shows a 7 ft SW swell with a long 13-second period and a huge energy reading of 1580. But the wind is a gentle cross-onshore, so it’s going to be a choppy, challenging session. This swell size is getting into expert-only territory, so keep that in mind.
After that, the next real glimmer appears at the very end of the run. On Wednesday morning, July 29th, it’s glassy again with 4 ft of a very long-period 16-second WSW groundswell and a strong energy reading of 817. The sets will be powerful and clean, perfect for a point break or reef, but with that period, it might close out on a beach break. Thursday the 30th of July keeps that energy going with 6 ft WSW swell, but with an onshore wind, it loses a bit of its shine.
So, to sum it up: get out there Wednesday morning the 15th. That’s the one. The rest is a mix of average days and wild, windy swells for the experienced crew. The very end of the month on the 29th and 30th looks promising, but it’s a long way off, so keep an eye on it.
Rusty.

Information about the Hornitos Surf forecast
The above surf forecast table for Hornitos provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Hornitos can be found by selecting the local surf guide option on the grey menu. Our Hornitos 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 (Hornitos) 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 Hornitos 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.
Hornitos is 22 km (14 miles) from the city of Mejillones. If you plan a holiday in Antofagasta, look for hotels and other accommodation in Mejillones. Mejillones has rooms for a wide range of budgets as well as car hire and transport links.
