The Lowdown

Alright folks, Rusty here. Let’s have a look at what the next couple of weeks are serving up.

We’ve got a solid run of small but clean swell on the horizon, mainly from the southwest, with a few standout sessions where the stars align. The first good surf hits Monday morning, September 7th. After that, there are a few gaps where the afternoons turn to junk, but the mornings keep delivering right through. Keep your eyes peeled for the early windows.

The main event is Hornitos. This spot is consistent, intermediate-level, and fairly exposed to the SW swell. The water is sitting at 66°, which is a massive 5° warmer than usual – that’s much warmer than normal for this time of year, so you can leave the thick wetsuit at home.

Monday morning, September 7th, is a beauty. Glassy conditions with a clean 2ft SW swell, a long 16-second period (that’s proper groundswell, lads), and combined wave energy is at 338 – a solid moderate energy. This is a true standout. Expect clean, lined-up sets. Crowds are possible here, so get in early.

Tuesday morning, September 8th is another cracker: glassy again, 3ft SW swell with a 14-second period, and energy at 294. Another morning to have the place to yourself if you’re quick.

We see a few morning windows on Thursday the 10th (glassy, 3ft SW), Saturday the 12th (glassy, 4ft SW but a shorter 9-second period), and then a really interesting one on Monday the 14th: a small 2ft SW swell but with a long 18-second period, clean conditions, energy at 376. That’s a sneaky good day for a point or reef setup.

After that, the pattern holds: Tuesday 15th, Wednesday 16th, and Thursday 17th all have glassy mornings with 3ft to 3ft SW swell. The energy starts to drop off a bit after the 17th, and by the 18th and 19th, the swell fades to 1ft – 2ft, with weak energy (65 to 131). Those days are better for a paddle or a snorkel.

The run picks back up on Monday, September 21st: glassy, 3ft SW, 14-second period, energy at 295. That’s another good morning to pencil in.

The standout pick of the whole 16-day run? Monday morning, September 7th, with Hornitos offering clean, glassy 2ft SW groundswell. The very long period means the waves will have real shape and power for their size. Get it while it’s glassy.

Stay safe, and I’ll see you in the water.

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.
