The Lowdown

Alright, Rusty here. Let’s have a look at what’s on offer for Hornitos over the next couple of weeks. I’ll be straight with you, it’s a mixed bag, and we’re waiting a fair few days before anything really peaks.

The water at Hornitos is sitting at a very warm 65°F, which is 5°F above normal for this time of year – that’s notably warmer than usual, so you might get away with a spring suit or even a shorty.

Looking at the first few days, Sunday the 9th kicks off with a 4ft south-west swell but the wind is cross-on and it’s looking a bit sad and choppy with combined energy at 756 (moderate). Not worth rushing out for. Monday the 10th sees a bit more push, with the swell building to 5ft in the morning and up to 5ft in the afternoon (combined energy hitting 1011 and 1251 – strong) but the cross-on wind is putting a chop on it both sessions. It’s a struggle.

Now, here’s where it gets interesting. Tuesday the 11th morning is still cross and messy, but the afternoon... that’s the standout in this whole window. The wind drops to zero, going completely glassy, with a clean 4ft south-west swell at 13 seconds (medium period). Combined energy is at 543 (moderate). That’s proper clean conditions for a wave. Hornitos is fairly exposed to the swell and the optimum direction is south-west, which matches up nicely. Be aware that crowds here are sometimes an issue, so you might have some company, but for a Tuesday arvo it could be worth the paddle.

After that, Wednesday the 12th and Thursday the 13th drop right off to a tiny 2ft – 3ft and mostly choppy. Not much to talk about. Friday the 14th is similar with knee-high slop.

We get a little pulse again on Sunday the 16th and Monday the 17th, with the swell building to 5ft in the afternoon on Sunday, and up to 6ft by Monday afternoon. Combined energy hits 907 and 961 (strong). But the wind is onshore or cross-on, so it’s going to be a bumpy ride. That 6ft is getting up there for beginners, more for the intermediate crowd.

The second week is honestly quiet. From Tuesday the 18th onward, it’s mostly 2ft to 3ft, with light cross-on winds and marginal or poor conditions. Nothing to set the world on fire. The combined energy drops to the low hundreds by the end of the week. The long gap of small, poor surf stretches from Wednesday the 12th right through to maybe Saturday the 16th, and then again from Tuesday the 18th to the end of the window.

Bottom line: Tuesday afternoon the 11th is your best bet by a long shot. Get out there when it’s glassy. Anything after that is a gamble on smaller, wind-affected waves until we see if the forecasts change.

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.
