The Lowdown

Hey, it's Rusty. Let's break down what's happening at Hornitos.

Hornitos is a spot that gets a mix of swell, and the water's running about 18°, which is a couple of degrees warmer than usual for this time – pretty notable.

Thursday the 27th is a total loss. Swell is tiny, like 1 to 2 feet, with a long period on the afternoon, but it's just poor conditions. Don't bother.

Now, Friday the 28th is the one to circle. Morning shows a 7ft swell from the south-west, with a 15-second period. The combined swell energy is 1810, so that's a healthy push. The wind is light from the west, offshore – glassy. That morning is your best shot for clean, powerful waves. The afternoon drops to 7ft and turns cross-on, so get out early. This is the highlight of the whole 16-day window.

Saturday the 29th sits around 5 to 6ft, period drops to 13 seconds, and the wind is cross-on in the afternoon. Still surfable, but not a patch on Friday morning.

From Sunday the 30th all the way into early September, it's a long, flat, and marginal run. Swell sticks between 3 and 5 feet, periods are short to medium (10 to 14 seconds), and the wind is often cross-on. The energy numbers are mostly in the hundreds – weak to moderate. There's a big gap of days with nothing worth getting excited about.

We get a couple of maybe-days around the 7th and 8th of September. The morning of the 7th: 4ft south-west swell, light offshore wind from the west, 11-second period. Could be clean. Then the 8th morning: 4ft, 15-second period from the south-west, light offshore. Combined energy is 884, so moderate. That morning might offer a decent session if the forecast holds.

After that, it fades again. The 11th of September is small, around 3 feet, with weak energy.

The one standout is absolutely Friday the 28th of August, first light. That's your best chance for some clean, solid groundswell with that offshore breeze. After that, it's a quiet stretch.

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.
