The Lowdown

Alright folks, Rusty here. Let’s chew the fat on what’s happening at Hornitos over the next couple of weeks.

It’s a slow start, but there are a few clean dawn patrol windows worth paddling out for. The water temp is a warm 66°, which is a solid 5° warmer than usual for this time of year – that’s very unusual, so you can leave the thick winter rubber at home.

The first real standout is Thursday morning, the 10th. We’ve got a clean 3ft SW swell rolling in with a 14-second period, and the wind is completely glassy – 0 mph from the NNW. That’s about as good as it gets. The water is flat calm, and the combined energy is moderate at 328. It’s an intermediate wave, so it’s a fun size for most. Just be aware that crowds are possible here.

The next morning worth noting is Tuesday morning, the 15th. Another glassy dawn, this time with a 3ft WSW swell, 14-second period, and the combined energy is a solid 415. The wind is dead calm, so it’ll be smooth as glass out there. Again, a nice little window for the intermediate crew.

Looking further out, Thursday morning the 24th is a promising one, but it’s a long way off. The forecast shows a tiny 1ft swell but with a very long 21-second period – that’s proper groundswell energy. With glassy conditions and a combined energy of 291, it’ll be super clean, but the size is small. It’s one to keep an eye on, but don’t bank on it just yet.

There are a few other mornings with glassy conditions and small surf, like Saturday the 12th, Sunday the 13th, Wednesday the 16th, and Saturday the 19th, but the swell is a bit ordinary – around 3ft to 3ft with short to moderate periods. They’re surfable but nothing to get too excited about.

The afternoons mostly get blown out by onshore WSW winds, so stick to the dawn patrol for the best of it.

Overall, the best on offer is Thursday morning the 10th and Tuesday morning the 15th. Clean, glassy, and a little bit of juice. Get on it.

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.
