The Lowdown

Alright, Rusty here. Let’s have a look at what’s on the cards for the Hornitos stretch over the next couple of weeks. Honestly, looking at the whole run, we are in for a pretty quiet, marginal period. The swell is mostly small, and while there are a few windows where the conditions come together, it’s not going to be firing by any stretch. The best advice is to pick your moments carefully.

We’re starting off Friday the 11th and into Saturday the 12th, and it’s pretty lackluster. Friday is a write-off with choppy, cross-onshore winds and poor surf. Saturday the 12th, however, shows a real glimmer. The morning is glassy – dead calm with a light SSW breeze, and that’s a major positive for clean waves. The swell is a tiny 3ft from the SW with a period of 12 seconds, which is a decent groundswell. The wave energy is moderate at 237. It’s surfable, but it’s very ordinary – just small, clean lines. The water is a balmy 66°, which is much warmer than usual for this time of year – 6° above the norm, so that's a treat.

Sunday the 13th morning is glassy again with a 4ft SW swell (9-second period), but it's a bit weaker. Still, if you want a paddle, the mornings are the only time to be out. The afternoons all week get ruined by onshore wind.

The standout, and I mean the only real standout in the whole outlook, is the morning of Tuesday the 15th of September. It’s calm, glassy conditions with a 3ft SW swell (14-second period). The combined wave energy is moderate (360). That long period will give you some nice shape, but at a beach break like Hornitos, that long-period groundswell can sometimes be a bit too straight – it’s better on a point or reef, but with the glassy conditions, it’ll be the cleanest you’ll see.

After that, it’s a long stretch of very small, ordinary surf. There are several days with nothing worth writing home about, just small waves with glassy mornings but poor afternoons. A gap of nearly a week of nothing exciting leads us to Tuesday the 22nd of September. That morning is glassy again with a 4ft SW swell and moderate energy (323). It’s the best of the second week, but still very much a small-wave option. The period is 11 seconds, so decent shape.

The rest of the run into the 26th is tiny, with swells dropping to 1ft and 2ft. It’s a quiet end to the outlook. For the experienced surfer, the 15th morning is your best bet, and for anyone wanting a clean small-wave session, the glassy mornings around the 22nd are worth a look. Crowds are sometimes an issue here, so on those small, clean days, expect a few others with the same idea.

Rusty, signing off.

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.
