The Lowdown
Alright, Rusty here, checking the surf for the next couple of weeks at Hornitos. It’s been a bit of a mixed bag, but there are some clean windows to get excited about.
The pattern starts with a few days of marginal, choppy conditions. We’ve got a solid pulse of long-period SSW groundswell, but the wind is a pain. The real standout is Tuesday, August 11th. The morning is still a bit cross and messy, but by Tuesday afternoon, the wind dies completely to glassy. That’s the money window. We’re looking at a clean 4.3ft swell from the SW with a 13-second period. The energy is moderate at 535, but the total lack of wind means smooth, proper lines. That’s the session to circle.
The other big moment comes a week later, on Monday, August 17th. That morning opens with glassy conditions and a building 4.3ft SW swell, period 11 seconds, and the energy is pushing 583. It’s looking really promising, though it’s a further out, so stay tuned. Tuesday afternoon the 18th gets a little bigger at 4.9ft, but the wind switches to a moderate cross-shore, which chops it up.
There’s a long, dry spell from the 12th through the 16th where the swell drops and the wind is onshore. Not worth it. We also get a clean, glassy window on the afternoon of Sunday the 16th, but the swell is only 2.3ft, so it’s tiny and weak.
For the rest of the run into the third week, the swell holds around 3.6ft to 4.3ft, but the wind is mostly a cross-onshore, so it won’t compare to that Tuesday the 11th. Water temp is about average for the time of year, nothing crazy.
Hornitos is consistent and fairly exposed to the SW. Crowds are "sometimes", so you might have a few friends out, but it won’t be packed. The best call is that Tuesday the 11th afternoon. Get in the water.

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.
