The Lowdown

Alright folks, Rusty here. Let’s talk about what’s on the menu for Hornitos over the next couple of weeks. It’s a bit of a slow burn, but there’s a real window of quality waiting for us out there, so don’t sleep on it.

Right off the bat, the water is running about 5°F warmer than usual for this time of year, which is a nice little bonus. The first few days are pretty lackluster. We’ve got some small SW swell, but wave heights are barely scraping 3ft, and while the mornings are glassy, the afternoons get chopped up by onshore breezes. Tuesday and Wednesday will be for the patient, not the hungry. The energy is weak, with values around 240 to 358, and it’s just not doing much.

There’s a gap of a few days with very little on offer, where the surf just sort of flatlines into the weekend. We go through a stretch where the swell drops off completely and the energy readings plummet to 67 and 100. It’s a quiet patch, that’s for sure. You’d be better off doing some maintenance on your board than paddling out for those ankle-biters.

Things start to shuffle back to life next week. By Monday the 22nd, we see that SW swell nudging back up to 3ft, but the wind is still on it in the afternoons, so you’ve got to be a dawn patrol warrior to get anything clean. A few mornings in there, like the 25th, have the period stretching out to 11 seconds and the energy starting to build – we’re talking 253 – with that light morning glass.

Now, for the real standout. The window we’re all waiting for is the morning of Saturday the 26th. That’s when it all clicks. We’ve got a 4ft SW swell hitting with an 11 second period, and the energy jumps to 618. The wind is dead calm, making for perfect, glassy conditions. This is what we’ve been waiting for.

And it gets better. The morning of Sunday the 27th is the absolute pick of the fortnight. The swell pushes up to 5ft, the period stretches to a solid 12 seconds, and the energy is cranking at 862. It’s got that long-period push that will wrap nicely into Hornitos, which is fairly exposed to that SW groundswell. With the offshore NW breeze cleaning it up, this is going to be proper. This is the one to circle in the calendar. This is a solid intermediate wave, but at 5ft it’s pushing a bit more size, so keep your wits about you.

The energy is strong, but it’s not insane—just good, powerful surf. We’ll see a drop-off after that, but there’s another little pulse on the 28th and into the first days of October, but the wind gets a bit messy, so those mornings will be your best bet. It’s not going to be as clean as that Sunday, but there will be waves.

So, in short: the next week is slow, but hold out. The morning of the 26th is good, but the morning of the 27th is the day. Make the call, wax up, and get out there when the sun’s up and the ocean looks like a pond.

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.
