The Lowdown
Alright folks, Rusty here. Let’s have a look at the surf ahead for Hornitos.
To start, the water is sitting at 66° – that’s much warmer than usual for this time of year, a real anomaly. It’s a nice bonus if you’re paddling out.
The first decent chance we see is Tuesday morning, July 28th. We’ve got a solid 5ft SW groundswell rolling in with a long 15-second period, packing a moderate 910 energy reading. The wind is light offshore from the WSW, so the surface should be clean. This is a consistent break, so expect some waves. It’s a fairly exposed spot, so it’ll catch the energy. But the forecast says "marginal surf forecast or questionable tide conditions," so it might not be the best session of the run. The swell is under 5ft, so it’s fine for intermediates.
Wednesday morning, July 29th, is a real standout. The swell drops a touch to 4ft from the SW, but the period is still a solid 13 seconds. The energy is moderate at 657. What makes this special is the wind: glassy conditions from the W at just 3 mph. That’s about as clean as it gets. The report says "expect good surf conditions" – that’s a rare thing here. For a consistent break, this is the pick of the first week. The swell is manageable for intermediates, and the glassy conditions will make it super fun.
The rest of the week through to the end of July and into early August is mostly marginal. We’ve got a mix of cross-onshore winds and small, weak swells. The energy drops into the 100s and low 200s on some days, and the wave state is often described as "poor surf conditions" or "light cross-onshore with small wind ripples." There’s a gap of several days here where there’s nothing really worth paddling out for.
Now, looking further out, there’s a promising pulse building for the second week. Thursday morning, August 6th, shows a 5ft SW groundswell with a very long 16-second period and a strong 1184 energy reading. The wind is light offshore from the WNW. That’s a lot of energy. The swell is over 5ft, so it’s getting into intermediate territory, but the period is so long that it’ll be better suited to a point or reef. At a beach break, it might break a bit too straight.
Saturday, August 8th, looks like the biggest call of the whole forecast. We’re looking at 6ft of SW swell, still with a long 14-second period, and the energy reading is a strong 1346. The wind is light offshore from the W. This is expert territory, as it’s over 5ft. The energy is high, and those long-period waves will have plenty of punch. The setup looks more interesting for a bigger, more experienced surfer. It’s a long-range call, so it’s promising but less certain.
After that, the swell slowly fades back down into the 3ft range with weaker energy and more cross-onshore wind, bringing us back to marginal conditions.
Overall, the best on offer is that glassy Wednesday morning. The big pulse on the 8th is the one to watch for the experts.

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.
