Alright folks, it's Rusty here. Let's have a look at the Hornitos forecast for the next couple of weeks.
It’s a bit of a slow burner to start, but there’s definitely some clean glass coming our way. The first few days are small, but the wind is looking good, which is half the battle. The water temp is about average for this time of year, nothing unusual there.
The standout session is shaping up to be Tuesday morning, the 14th of July. We’re looking at a clean 4ft SW groundswell, with a period of 15 seconds, meaning plenty of energy and long waits between sets. The combined energy is pumping at 739 (moderate wave energy), and with the wind going glassy, it’s going to be a picture-perfect morning at Hornitos. That’s the one to circle. The swell direction is a solid SW, which is the optimum for this fairly exposed spot.
The days leading up to it are a mixed bag. Friday the 10th has got a little 3ft SW swell, but the wind is mostly onshore or light, and the energy is moderate at 451 (weak wave energy). Saturday the 11th is similar, with a 4ft SW swell but not much else going for it. Sunday the 12th has a little 3ft SSW groundswell with a 16-second period, and the afternoon goes glassy, so it could be worth a look if you’re desperate.
After Tuesday the 14th, the swell drops off a bit through Wednesday and Thursday, with 4ft to 3ft SW groundswells, but the wind stays glassy through the afternoons, keeping it clean. The energy drops back to 277 (weak wave energy) by Thursday afternoon.
Then we get a gap. Friday the 17th is tiny, just 2ft SW, and the energy is weak at 131. Not worth getting wet for.
The second week brings a bigger pulse. On Saturday the 18th of July, the swell jumps to 7ft from the WSW, with a 14-second period, and the combined energy goes through the roof at 1729 (strong wave energy). That’s a lot of water. However, the wind is a light cross-onshore, and the reports are calling it marginal. It’s going to be big and punchy, with some chop on it. For a beach break, this setup might be more interesting for the kite surfers than the paddle crew. The swell size is over 8ft, so this is expert territory only. Sunday the 19th is similar, with a 6ft WSW swell, but the wind gets a bit stronger and more cross-onshore, making it choppy. The energy is still strong at 1306, but the quality drops.
The rest of the second week sees the swell ease back to 5ft to 4ft, but the wind stays mostly cross-onshore or onshore, with the energy dropping back to 399 (weak wave energy) by the end. The period drops below 8 seconds on the 22nd and 23rd, meaning junky, short-period windswell. Not much to get excited about in that last week.
So, the call is simple: keep your eyes on Tuesday morning, the 14th of July. That’s the cleanest, most promising session of the whole run.
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.
