The Lowdown
Alright folks, Rusty here. Let’s break down what’s on the table for the next couple of weeks.
Straight up, the first few days are not doing us any favours. The opening has tiny swell and the wind is all wrong, so we’re waiting for something to happen. It’s all about one spot: Hornitos.
Wednesday the 26th and Thursday the 27th are a bust. Waves under 2ft, and the wind is either onshore or cross-onshore. Water temp is about normal for this time of year, nothing crazy.
The first real chance comes Friday the 28th. That morning, a 7ft SW groundswell shows up with a very long period of 15 seconds. That’s serious energy (1810), but there’s a catch. That long period groundswell can make beach breaks close out, and Hornitos is fairly exposed to it. Still, with flat, glassy conditions and a light offshore wind from the WSW, it’ll be clean if there’s a channel. This is too big for beginners, but intermediates can handle it.
Saturday the 29th drops to 6ft in the morning, and the period drops to 13 seconds. Wind stays cross-onshore, so it’s a bit lumpy. Energy is still solid at 968. It’s still a decent option for experienced surfers.
From Sunday the 30th onward, the swell fades. You get a 4ft morning on Sunday, but the wind goes cross-onshore by afternoon and quality drops. Monday the 31st is back to poor conditions, with 9 mph cross-onshore winds chopping up the 5ft swell.
By Tuesday the 1st of September, we’re down to 4ft and the wind is offshore that morning, so worth a paddle, but the energy is weak (504).
Wednesday the 2nd of September has a weird one. The afternoon shows a 1ft swell but with a very long period of 19 seconds. That’s barely a ripple.
Thursday the 3rd of September is flat, but Friday the 4th has a 4ft morning with a 14 second period and clean offshore wind. That’s a sleeper.
The real standout in the second week is Saturday the 5th of September. The morning brings a 5ft SW swell with 13 second period, light offshore wind, and clean conditions. Small but clean.
Sunday the 6th of September and beyond taper off into smaller, cross-onshore slop. By the 10th of September, it’s flat with poor conditions.
To wrap it up: Friday the 28th of August morning is your best shot for size and clean conditions. Saturday the 5th of September morning is the next call for cleaner shape on a smaller wave. Everything else is a toss-up.
Stay safe out there.
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.
