The Lowdown
Alright folks, Rusty here. Let’s get into it for Hornitos.
We’ve got a mixed bag coming up, but there’s a real standout hiding in the second week. The water is sitting at 17.4°, which is a touch warmer than normal for this time of year, so it’s pretty comfortable.
The first few days are going to be a bit of a grind. Sunday the 19th starts with a clean 4ft swell from the WSW, and the wind goes glassy in the afternoon. That’s the best of the early days, but it’s pretty small. Monday the 20th has a similar story – glassy afternoon with 3.5ft from the WSW. Tuesday through to Saturday the 26th is mostly small and choppy, with a few glassy windows but nothing to get excited about. The surf is there, but it’s not going to blow your mind.
Then we hit the real deal. Tuesday the 28th of July is the one. The morning swell is 5.5ft from the WSW, and by the afternoon it’s pushing 7ft from the same direction. The combined energy jumps into the strong range (2057), and the period is a very long 16-17 seconds. This is proper groundswell. The wind is a light cross-onshore, so it’ll be a bit textured, but the energy is real. This is a big swell for Hornitos, so it’s strictly for experienced surfers – over 8ft rules out beginners. The very long period means the waves will be fat and powerful, best on a point or reef if you can find it. This is the standout of the whole forecast.
Wednesday the 29th keeps the size up at 5.5ft in the morning, but the energy drops a bit (1069). The following days, Thursday the 30th and Friday the 31st, see the swell fade back to 4ft and 3ft, but with clean glassy conditions in the afternoons. The first of August has a couple of nice glassy mornings with 2.5ft swell from the WSW, perfect for a longboard or a fish.
The run ends on Monday the 3rd of August, with a new pulse of 5.5ft from the WSW, but the wind is onshore and messy, so it’s not a great finisher.
Overall, we’ve got a lot of small, clean windows, but the real power comes on the 28th. If you’re an experienced surfer, that’s the day.

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.
