The Lowdown
Alright, folks, Rusty here. Let's talk about what's on the table for Hornitos over the next couple of weeks. It's a pretty quiet stretch, but there are a few windows that might get you out.
The overall pattern is a bit subdued. We've got some consistent swell, but it's mostly small to modest, and the wind is almost always cross-on, which keeps things a little messy. There's no real standout day that screams "drop everything and go," but the best chance for a decent session looks like Monday the 29th, with a modest 6ft swell from the WSW carrying a moderate energy of 968. The water is running pretty warm at 65°, which is much warmer than usual for this time of year – a good 4°F above normal, so you can leave the thick wetsuit at home. The wind is a light cross-on at 6 mph, so it's not perfect, but it's manageable. The period is 13 seconds, giving it a bit of push.
For the rest of the first week, things drop off. Sunday the 30th sees smaller 4ft swell, and from Monday the 31st through the first few days of September, we're looking at swell heights around 4ft to 4ft, still with those light cross-onshore winds. The combined energy dips into the 300s and 400s, so it's weak. A few mornings have a brief window of offshore wind, but the tide or conditions aren't quite coming together.
The second week stays pretty flat. Thursday the 3rd has a long-period 18-second swell from the SW, but it's only 2ft, so it's not generating much. Friday the 4th sees a slight bump back to 5ft with a 14-second period and offshore wind, giving a moderate energy of 763 – that's the best of the second week, but it's still marginal. From there, it's a slow grind of small, weak swells with cross-on wind, and the combined energy mostly stays in the 300s to 400s. By the 13th, we're back to 2ft with a 16-second period, but again, it's just not enough.
Honestly, there's no red-letter day here. The best bet is Saturday the 29th morning, but even then, it's not firing. If you're really keen, you might get a few grovelly waves on the Friday the 4th afternoon, but don't expect much. The rest is a lot of waiting.
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.
