The Lowdown
G'day, I'm Rusty. Let's have a look at what's on the cards for Hornitos over the next couple of weeks.
We're starting off a bit slow, but don't write it off just yet. There's a real build-up of energy through the period, and a couple of windows that look like they'll be worth paddling out for. The water's sitting at 63°, which is a touch warmer than normal for this time of year, so you might not need the thickest steamer.
First up, we've got a few days of small, average surf. Sunday the 19th has some 4ft swell from the WSW with a 12-second period, but the wind is cross-on from the NW at 3 mph, so it's a bit messy. The combined energy is moderate (507). The next few days don't look much better, with the swell dropping and the wind staying on or cross-onshore. Monday afternoon the 20th is worth a mention though – the wind goes glassy, which is a major positive, and the swell is 4ft from the WSW. It's clean, but the energy is still moderate (367). It's a small, glassy session, but the forecast says "expect good surf conditions", so it might be your best early bet.
The real standout, and I mean the one to circle on the calendar, is Monday the 27th of July. Monday afternoon, the wind goes glassy, the swell is 3ft from the WSW, but the period jumps to a very long 16 seconds. That's a proper groundswell. The combined energy is strong (850). This will be clean, lined-up, and the long period will mean better-shaped waves, especially at a point break or reef. Given it's a consistent spot, this is the one.
The other big nod goes to Wednesday the 29th of July. The afternoon session looks glassy again, with a solid 5ft of swell from the SW and a 14-second period. The combined energy is strong (901). That's a powerful, clean swell. It's a little over 5ft, so it's getting into intermediate territory, but for the experienced surfer, this is a cracker.
There's a bit of a gap in the middle, with Tuesday the 22nd and Wednesday the 22nd being poor with choppy conditions. Stick to the 27th and 29th.
Then, into the first week of August, we have another promising window. Monday the 3rd of August afternoon sees glassy conditions again, with a 5ft swell from the SW, a 12-second period, and strong combined energy (848). The forecast says "expect very good surf conditions", so that's another one for the diary, but it's further out, so keep an eye on it.
Remember, long-period swells can break a bit straight at beach breaks, so Hornitos should handle it well. Crowds are sometimes a factor here, so you might have some company.
Alright, that's the run-down. Keep an eye on the 27th and 29th of July, and the 3rd of August. Stay stoked.
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.
