The Lowdown
Alright folks, Rusty here. Let’s look at what’s on the menu for Hornitos over the next couple of weeks.
Straight up, this is a tough run. We’re looking at a solid 16-day window, but the surf is really struggling to get its act together. The wind is nearly always cross-onshore, and the forecast keeps calling it marginal or poor. There’s no standout session that’s going to blow your mind, but we’ve got to pick the best of a tricky bunch.
The first chance to get wet comes on Monday the 3rd of August. It’s small, with a 4ft swell from the SW, but the water is a toasty 66°, which is a whopping 5° warmer than usual for this time of year. That’s a freaky anomaly, so you’ll be comfortable in boardies.
The best bet on offer looks like Thursday the 6th of August. The swell builds to 5ft from the SW, carrying a long 14-second period. That’s proper groundswell energy, with the combined energy sitting at a solid 997 (moderate to strong). The catch is the wind is a light cross-on, so it’ll have a bump on the face. Still, compared to the rest of the week, that’s the pick of the litter.
The following week gets a little interesting. From the 9th through the 10th, there’s some 4ft SW swell with a 14-second period, but the cross-onshore wind is a constant problem. The combined energy flirts with 985, so there’s power there, but it’s not going to be clean.
Then, on Thursday the 13th of August, we get a rare moment of glass. The swell drops to 2ft from the SW with a very long 18-second period, and the wind goes glassy. That’s a beautiful, clean surface, but the energy is low (355). It’s a mellow, long-period groundswell that’s better suited for a point or reef, but at Hornitos it might just be a little too weak to hold together. It’s a gamble, but if you’re patient, it’s the only real clean window in the whole 16 days.
The last possible chance is on Tuesday the 18th of August. We see a 5ft SW swell with a 14-second period and a combined energy of 813, and the wind is *on* in the morning. That’s a solid session on paper, but it’s far out and the forecast confidence is low. It’s worth keeping an eye on, but don’t book the day off yet.
Overall, don’t expect much. The wind is the enemy here, and the swell is mostly small and bumpy. If you *have* to paddle, aim for Thursday the 6th or take a chance on the glassy morning of the 13th.
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.
