Hey, Rusty here again. Let’s break down the surf for Hornitos in feet and miles per hour.
The next week or so is looking pretty ordinary, to be honest. We’ve got a consistent SW groundswell running, but the wind is mostly coming from the same direction, keeping it a bit choppy and bumpy. The water’s at 63°F, which is about normal for this time of year – no surprises there.
The best bet in the whole run, by a long shot, is Sunday the 12th of July. The morning shows a clean 5ft SW swell with a long period of 18 seconds, and the combined wave energy is pumping at 1512 (moderate to strong energy). But the real standout is the afternoon: glassy conditions, a solid 5ft SW swell, and the energy jumps to 1525. That’s the pick of the window for experienced surfers. That long period groundswell will wrap in nicely, and with the glassy surface, it’s going to be clean. Keep in mind, long period SW swells like this work a treat at spots like Hornitos, but the long gaps between sets can make it a little tricky to get into a rhythm.
If that Sunday is too big, Monday the 13th still offers a good look. The afternoon shows 6ft SW swell, again glassy, though the period drops to 13 seconds. Energy is still solid at 982. It’s going to be a good day, but the Sunday afternoon is the real highlight.
Tuesday the 14th morning is also glassy with a 5ft SW swell, but the energy drops off to 522, so it’s a smaller, cleaner option for an easier paddle.
After that, we’re looking at a few days of smaller, cross-on winds and falling energy. It tapers off pretty quickly.
So, to sum it up: the first week is mostly a write-off with the onshore wind. Hold out for Sunday the 12th of July afternoon – that’s the one you want to be in the water for. It’s the only true standout in the next 16 days.
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.
