The Lowdown
Right then, let’s have a look at what’s cookin’ for Hornitos over the next couple of weeks.
The first bit of decent surf shows up on Monday the 7th, but it’s real touch-and-go. We get a clean, glassy morning with a 2ft swell from the SW and a very long period of 16 seconds. That kind of period, that’s proper groundswell, so the energy is there with a combined reading of 326. Glassy wind and that long period should make for some nice, clean lines, but this kind of long-period stuff can be a bit tricky at a beach break – it might just want to jack up and close out. Still, that’s the pick of the week for sure.
After that morning, the wind swings onshore in the afternoon and it’s pretty much game over for the rest of the week. Tuesday morning (8th) has another glassy window with a clean 3ft SW swell, but again it’s only the morning session before the sea breeze ruins it. The rest of that week is mostly poor, with onshore wind and messy conditions. Even on Saturday the 12th, the swell bumps up a little to 4ft, but that short period of 8 seconds means it’s gonna be weak and crumbly. It’s surfable, but nothing to get excited about.
There’s a real gap in quality here after the first couple of mornings. The next real standout isn’t until Monday the 14th. That morning we get another glassy session with a 2ft SW swell and a very long period of 18 seconds. The combined energy is a solid 373 for such a small wave, which tells you it’s got punch. Super clean, glassy conditions. It’ll be small but beautifully shaped if you can find the right bank.
The pattern repeats again: a good, glassy morning on Tuesday the 15th (3ft SW, 15 seconds) and then another on Monday the 21st (2ft SW, 16 seconds, combined energy of 357), with the wind going onshore every afternoon. So, if you’re serious, you set your alarm for dawn.
The water temp is about average for this time of year, so no need for a thick wetsuit. Crowds are only a "sometimes" thing at Hornitos, so you’ve got a good chance of getting a few to yourself on those clean morning glass-offs.
To wrap it up: The best windows are the mornings of Monday the 7th, Monday the 14th, Tuesday the 15th, and Monday the 21st. The 14th looks like the best of the bunch for pure, clean lines if you can handle the very long period. The rest of the time, you’re better off waiting for the next morning.

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.
