The Lowdown
Alright folks, Rusty here. Let’s talk about what’s shaping up for Hornitos.
Right off the bat, I gotta be straight with you – the next couple of weeks are looking pretty grim for any kind of decent surf. We’ve got a solid 16-day window, but honestly, there’s nothing that’s really gonna get the heart pumping. The whole period is plagued by cross-onshore winds that are just messing up the surface, leaving it choppy and bumpy. The water is running at 66°, which is much warmer than normal for this time of year, so at least you won’t need a thick wetsuit if you’re desperate for a paddle.
For the first week, from Saturday the 1st right through to the following Saturday the 8th, it’s a real struggle. The swell hangs around 3 ft to 5 ft from the SW, with a moderate combined energy (405 to 648), but the wind is almost always cross-on, making it a choppy, bumpy mess. The best of a bad bunch looks to be the morning of Wednesday the 5th, when we get a brief moment of offshore wind from the W and WSW, with a 5 ft SW swell and a decent 12-second period. The energy jumps to 622, which is moderate, but it’s still only a marginal call. That’s about as good as it gets in the first week, and it’s not saying much.
Then we get a bit of a spike on Thursday the 6th. The morning sees a 5 ft SW groundswell with a very long 16-second period, and the energy rockets up to 1215 – that’s strong wave energy. The wind is offshore from the WSW, so it could be clean. But here’s the caveat: that long period groundswell can be a bit tricky at a beach break, making it break a bit too straight. It’s still a marginal call, but if you’re an experienced surfer, this is the standout of the whole forecast. For beginners, that 5 ft is starting to get a bit big.
The second week is a real fizzer. From the 9th onwards, the swell drops, and the winds stay stubbornly cross-on or onshore. The energy values drop back to weak to moderate (189 to 560). The only glimmer is on the afternoon of Friday the 14th, when we get glassy conditions with a 2 ft SW groundswell and a 15-second period, and the energy is a weak 297. The "expect good surf conditions" flag is there, but with such a small swell, it’s more of a longboard or cruiser wave than anything with power.
So, to be honest, there’s not a single day where I’d say “drop everything and go.” It’s a long, blank stretch. The only standout is Thursday the 6th morning for the more experienced crew, but even that’s a gamble. The rest is just a waiting game.
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.
