The Lowdown

Rusty here, with the imperial version.

Looking at Hornitos over the next 16 days, the start is quiet. We’ve got a few days of small, average waves before the real standout hits right at the end of the run.

On Saturday, August 15th, there’s a small SW swell around 3ft, with a 13-second period and moderate energy (267). Winds are light offshore from the West in the morning, so the surface will be clean, but it’s pretty small. Water temp is 64°, which is about 4° warmer than normal for this time – very unusual and actually quite warm.

Sunday the 16th afternoon brings a tiny 3ft SW groundswell, but with a very long 16-second period and moderate energy (409). The wind goes glassy from the WNW, so the surface will be clean. With that period, you’ll get long waits between sets, but the shape could be fun on the right board.

Monday the 17th through to Friday the 21st is mostly poor. Cross-onshore wind, small swell, and not much to chase. Friday the 21st sees a bit of a break: glassy wind again with a small 3ft SW swell (9-second period) and weak energy (290). It’s surfable, but nothing special.

The weekend of the 22nd and 23rd is poor. Then from Monday the 24th to Wednesday the 26th, swell drops as low as 1ft. It’s a real flat spell in there for about 4-5 days.

The big news is Friday, August 28th. A strong WSW swell hits at 8ft in the morning with a 14-second period and very strong energy (2285). By Friday afternoon, it drops slightly to 7ft, but the wind goes glassy from the West. That’s clean, powerful groundswell. This is strictly for experienced surfers – 7ft-plus with that energy is serious. Beginners should stay well clear.

Saturday the 29th morning holds at 6ft with glassy winds and strong energy (874) – still a great option for good surfers. By the afternoon it drops to 5ft and the wind goes onshore, so the window narrows. Sunday the 30th is back to small 4ft swell with onshore wind.

The standout: Friday, August 28th afternoon – glassy, clean, and a solid 7ft WSW groundswell. Saturday the 29th morning is a very close second for a clean 6ft session.

Crowds at Hornitos can pop up sometimes, so be ready for company on those good days.

Be patient – the first week and a half is slow, but that end-of-month pulse is a proper pay-off.

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.
