The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s on offer. It’s gonna be a bit of a quiet stretch, but there are a couple of windows worth paddling out for.

We’re looking at Hornitos, and for the first week and a half, it’s a real struggle. The swell is there, but it’s not happening. The wind is stubbornly cross-on, and the wave quality is just not there. The combined swell energy is moderate, often in the 400-900 range, but it doesn’t matter when the conditions are choppy or the tide is wrong. The best we can say is that on Thursday the 6th of August, there’s a morning with a light offshore breeze, 4ft of SW swell at 12 seconds (moderate period, 897 energy), but it’s still labeled as marginal. Same goes for the afternoon with a 5ft SW swell at 14 seconds (997 energy), but the wind swings cross-on. It’s frustrating because the swell is there, but the wind just won’t cooperate.

The pattern continues through the weekend and into the next week. We get a bit of a bump on Sunday the 9th with a 5ft SW swell at 14 seconds (973 energy) in the afternoon, but again, cross-on wind. The water temp is about average for the time of year, nothing unusual. By Monday the 10th, the afternoon sees a 5ft SW swell at a very long 15 seconds (1046 energy), which is a proper groundswell. That kind of period usually means better-shaped waves, but at a beach break like Hornitos, it can break a bit too straight. Still, the energy is moderate, and the light breeze is just cross-on, so it’s not a total write-off, but it’s not a standout.

The real standout window is looking like Wednesday the 19th of August. There’s a solid 6ft SW swell rolling in with a very long period of 15 seconds, and the combined energy jumps to 1455. That’s strong wave energy. The morning has a light cross-on, but the afternoon turns clean with a light offshore wind from the west. The swell drops to 6ft but still holds that 15-second period (1229 energy). This is the best on offer. For experienced surfers, that 6ft at a long period will have some punch, and with cleaner wind, it’ll be the most fun we’ll see all forecast. Beginners might find it a bit much.

The following day, Thursday the 20th, is still okay with a 5ft SW swell at 14 seconds (787 energy) and a light breeze, but it’s cross-on again. The magic fades out pretty quick after that.

So, to sum it up: the first ten days are a grind of marginal conditions. The one true standout is the 19th of August, especially the afternoon. That’s your window. The rest? Keep an eye on the forecast, but don’t cancel your plans.

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.
