The Lowdown
Alright folks, Rusty here. Let’s get stuck into it.
The next couple of weeks are a bit of a mixed bag. We’ve got a solid, consistent SW groundswell running for a while, but the wind is the real spoiler for most of it. There are a few windows where it all lines up, and we’ll get to those. But be prepared for plenty of lumpy, cross-onshore slop in between.
The action starts on Monday, August 3rd. The morning at Hornitos is the standout early call. The swell is a clean 3ft from the SW with a 12-second period. The wind is glassy, and the water temp is about average for this time of year. It’s not huge, but it’s clean, and the moderate wave energy (372) is enough to get you into a few. This is the one to paddle out for.
From Monday afternoon through to Wednesday the 5th, the swell actually builds a bit, pushing up to 5ft, and the energy gets more moderate. But the wind swings cross-onshore and it gets a bit lumpy. It’s surfable, but you’ll be fighting the wind for it. This stretch is more about getting wet than getting good ones.
Thursday the 6th brings a jump in period to 16 seconds. That’s a proper groundswell. The swell is 4-5ft and the energy is strong at 1006. The catch is that wind is still not your friend. It’s a bit of a tease, and with that long period, it might be breaking a little straight at a beach setup like this. You’ll want to be on your shortboard if you’re out there.
The weekend rolls in and it’s a bit of a write-off. Friday the 7th and Saturday the 8th see the swell drop back to 4ft, but it’s still cross-onshore, getting choppier in the afternoons. It’s the kind of surf that has you checking the cam more than your board. You might get a few inside ones, but it's nothing to get excited about.
Sunday the 9th and Monday the 10th show a little more promise. The swell bumps back up to 5ft on Sunday morning, and the energy is strong (835). But again, the light cross-onshore breeze is there to mess with the surface. By Monday afternoon, the swell drops to 3ft but the period jumps to 16 seconds, which will be interesting. Still, the wind keeps it from being great.
Then we hit a bit of a dry spell. From Tuesday the 11th through the middle of the following week, things just get smaller and the wind keeps messing with it. The period stays long, but the size just isn't there. It's a waiting game. The water is still about average, but the energy is weak. If you're a beginner, this is a good time to do something else.
Now, looking into the second week, there’s a glimmer on the horizon. Monday, August 17th, we see a jump in size to 5-6ft with a 14-second period and the energy is very strong at 1508. This is a real swell. The wind is onshore, so it won't be pretty. This one is likely too big and bumpy for anyone but the experts. It’s a promising sign for the days after, but it’s a long way out, so don't book your flights just yet. It’s one to watch.
So, for the 16-day window, the clear standout is the glassy dawn patrol session on Monday morning, August 3rd. It won’t be big, but it will be clean. The other potential is the swell on the 17th, but that’s a promise for the future with some caveats. For the rest, it’s a lot of chop and frustration.
Rusty out.

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.
