The Lowdown

Alright folks, Rusty here. Let’s talk about the surf ahead for Hornitos. It’s a bit of a mixed bag, so let's get into it.

The first bit of real hope shows up on Sunday the 9th. It’s not huge, but there’s a clean 4ft SW swell rolling in with a 14-second period. The water’s a toasty 65°, which is much warmer than normal for this time of year – you won’t need a thick suit, that’s for sure. That energy is reading at 756, which is moderate, but it’s there. It’s a start.

Monday the 10th sees the swell bump up a touch to 5ft, also from the SW, and the period stays around 13-15 seconds. The energy is climbing, 1011 to 1251, but the wind is crossing onshore and making things a bit lumpy. Not the cleanest, but it’s pushing some water.

Now, the standout in this whole stretch has got to be Tuesday the 11th. The swell settles to a still-solid 4ft from the SW, with a 13-second period. But the real story is the wind. We’re looking at a glassy morning with a 3 mph SSE breeze, and the afternoon goes cross-off and clean. This is your window for the best conditions. The energy is moderate at 569, but the clean surface will make it feel way better than the number suggests. This is the one to circle.

After that, things get a little quiet. Wednesday the 12th drops off to 2ft and the conditions turn poor. We then slide into a few days of small, cross-onshore slop. There’s a pulse of long-period energy on Thursday the 13th, with a 17-18 second period, but the size is only 2-3ft, which isn't enough to do much with. The rest of that week is pretty forgettable, with small waves and onshore breezes.

We get a bit of a bump on Monday the 17th. It’s the biggest of the forecast, pushing 5-6ft, but it’s coming with a shorter 11-second period and cross-onshore winds, so it will be a bit of a messy, wind-affected one. Might have some push, but it won’t be clean.

The final week looks like a slow grind. From Tuesday the 18th onwards, we’re mostly looking at sub-3ft surf with a lot of onshore wind and poor conditions. The energy drops out, and by the 23rd and 24th, we’re down to knee-high dribble with weak energy (down to 93-193). There’s a long-period SSW swell on the 24th, but with only 1-2ft of size, it’s not going to break. It’s a flat spell.

So, to wrap it up: don’t sleep on Tuesday the 11th. That’s the clear standout for clean, fun waves. The other days are mostly about small, average conditions. Get out there when the wind is right.

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.
