The Lowdown
Alright folks, Rusty here. Let's have a look at what's coming our way.
Right off the bat, I gotta be straight with you – the first few days are a bit of a write-off. We're looking at a slow start, with nothing worth paddling out for on Saturday the 8th. The swell is small and weak, with combined energy readings around 281, and the wind is cross-onshore, making it a choppy mess. Sunday the 9th isn't much better, with a bit more size but still messy conditions.
The real story starts to unfold on Monday afternoon, the 10th of August. We've got a solid 5ft swell rolling in from the southwest, with a very long period of 15 seconds. That's proper groundswell energy, and the combined energy is a healthy 1251. The wind swings around to a light cross-offshore breeze, and the forecast is calling for very good surf conditions. This is the standout session of the whole outlook, no question. Hornitos will be the spot to be. The water temperature feels about average for this time of year, so no drama there.
Tuesday the 11th holds some clean, smaller waves in the afternoon, with that cross-offshore wind again, but it’s a step down in size. After that, we hit a real lull from Wednesday the 12th all the way through to Sunday the 17th. The swell drops right off, and the wind is mostly onshore or cross-onshore, leaving us with poor-to-marginal tiny surf. That's a long stretch of flatness.
We see a little pulse return on Monday the 17th, with 4ft to 4ft swell, but the wind is straight onshore. It's a tease. The real gem is waiting for us on Wednesday the 19th of August. The morning brings a clean 4ft southwest swell with a 14-second period, and the wind is a perfect, glassy offshore from the northwest. It's going to be clean, lined-up, and uncrowded. The afternoon stays glassy too, with a smaller 4ft wave. That Wednesday morning is the second real standout if you can wait that long.
The final week tapers off again, with small, weak swells and mostly onshore winds. Nothing to get excited about.
So, to wrap it up: the best bet is Monday afternoon, the 10th of August, for the biggest, cleanest energy. If you miss that, Wednesday morning, the 19th of August, is your next best chance for some glassy, fun waves. Don't bother with the long gaps in between.
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.
