The Lowdown

Alright folks, Rusty here. Let’s get into it.

We’ve got a 16-day stretch ahead, and I’ll be honest with you, it’s a tough one. The long-range models are showing a constant supply of small, weak swell, and the conditions are just never quite right. There’s a persistent trickle of long-period groundswell, but the energy is low and the winds are a constant problem. The best wave of the whole period is a marginal one, and even then, it’s a far cry from a classic day.

The whole run is a flat spell, really. Days and days of poor surf conditions or marginal forecasts, with nothing to get excited about. The only place showing any pulse at all is Hornitos, a consistent intermediate spot that’s fairly exposed to the SW. The water is sitting at 65°, which is a whopping 5° warmer than normal for this time of year, so you’ll be in a spring suit or even a shorty.

The first hint of something rideable shows up on Thursday, September 3rd, but it’s a tease. We’re looking at a 2ft SW swell at a very long 18 seconds, but with a light cross-onshore breeze and a "poor surf conditions" tag. The combined energy is moderate (410), but the wind is just enough to mess it up. Friday the 4th is a little better, with the swell tickling 4ft from the WSW at 14 seconds, and the wind goes light onshore. The energy bumps up to a moderate 718, but it’s still a marginal call. The light breeze is about as good as it gets for this break.

The consistency is there, with small, long-period pulses rolling in for days, but the wind is almost always onshore or cross-onshore. The few times the breeze goes light offshore, the swell is tiny. For example, the morning of Sunday, September 6th has a 2ft, 18-second swell with a light offshore wind, but it’s a mere 428 energy and tagged as marginal. It’s a glassy wave, but it’s knee-high.

The best call of the whole 16 days is a toss-up between the morning of Friday, September 4th and the morning of Saturday, September 12th. Friday the 4th has a 4ft swell from the WSW with a 14-second period, light offshore wind, and the highest energy of the entire run (649). That’s the biggest, cleanest wave you’ll see. The morning of Saturday the 12th has a 4ft, 9-second swell with a light offshore breeze, but the period is shorter, meaning the wave will be weaker and more crumbly. The energy is lower (294) too. So, Friday the 4th is the one to aim for, but don’t expect a classic. It’s the least bad option.

After that, it’s a slow bleed. The swell drops, the winds shift, and the combined energy falls into the 100-300 range. The last week of the forecast is a flat, white-capped mess. The afternoons of the 9th and 10th are particularly grim with a gentle cross-onshore breeze making it choppy. By the 17th and 18th, the energy is down to 100 or less, and the swell period is dropping to 7-8 seconds, which is just wind chop. The whole thing flat-lines.

So, to sum it up: if you’re desperate, point your car at Hornitos on the morning of Friday, September 4th. Bring a small board, maybe a fish, and don’t expect much. The rest of the 16 days is a write-off for a proper paddle session. It’s the kind of setup that’s more interesting for the kite crew than us surfers.

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.
