Alright, listen up. Rusty here, with a look at what’s coming our way. We’ve got a bit of a slow start, but there are some real gems hiding in this forecast if you’re patient.

The first few days, Sunday the 12th and Monday the 13th, are all about small, clean conditions. Sunday morning you’ll find Hornitos with a little 2.6ft of SSW groundswell, but it’s got some serious grunt for its size – a 16-second period means proper long lines. The water’s sitting at 62°, which is pretty much bang on average for the time of year. With glassy, near-calm conditions and light airs, that morning session will be a lonely, fun little affair. The crowd factor is there, but "sometimes" means you might have it to yourself. The combined energy is 367 (moderate), so there’s enough push.

That Sunday afternoon holds a touch more size at 3ft from the SSW, and still glassy. Monday gets a bit messier with a cross-onshore wind, so leave the board on the rack.

Now, for the real standout. If you can wait, circle Saturday the 18th. That afternoon session at Hornitos is where it’s at. We’ve got 5.6ft of WSW swell, coming in with a 11-second period. Sure, that’s not a super long period, but the combined energy is 769 (moderate to strong), and the wind is forecast to be glassy. That’s a recipe for clean, punchy waves. This is the best on offer – a solid, fun size with offshore texture. Keep it in mind for the weekend.

The swell builds further from there. Sunday the 19th morning shows a bigger 7.2ft from the WSW, with a very long 13-second period. The combined energy jumps to 1699 (strong). However, the wind is a light onshore, making the conditions questionable. This is a powerful swell – one for experienced surfers only, as 7.2ft is big, but it might be a bit lumpy. That same afternoon the cross-on wind picks up, so it’s likely choppy.

After that, the second week gets a bit inconsistent and bumpy. Tuesday the 21st afternoon sees a stiff 12 mph cross-on wind with 6.2ft swell – messy. That pattern of cross-on or onshore wind and marginal conditions sticks around for a lot of the following days. The period drops to 8-10 seconds, so the quality fades.

Don’t give up entirely, though. Saturday the 25th afternoon should see a return of glassy conditions with a 4.3ft SW swell, which will make for a fun, small afternoon. And finally, Monday the 27th afternoon wraps the forecast with glassy winds and a clean 3.9ft SW swell. It’s not huge, but it’ll be clean.

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.
