The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s comin’ down the line for Hornitos. It’s a bit of a slow burn to start, but there’s some real promise tucked away in this forecast if you’ve got the patience.

The first week is pretty quiet. We’ve got small swell rolling in from July 21st, but it’s all cross-on and the conditions are just ordinary. The water’s sitting at 64° – a touch warmer than normal for this time of year, which is a nice little bonus if you’re in the water anyway. The combined swell energy is weak for most of that first stretch, hangin’ around 329 (weak energy), so not much to get excited about.

Things start to shift on July 24th. Friday afternoon sees a bit of a glass-off with WNW wind going dead calm. The swell is a modest 4ft from the SW, but with that glassy surface, it’s your first real chance to grab a clean wave. The energy is still moderate at 352 (moderate wave energy), but the quality of the ride will be way better than the height suggests.

The real standout, though, is Saturday July 25th. The afternoon session is glassy again, with a clean 4ft SW swell pushing in. The period stretches out to 11 seconds, giving the waves some proper shape and push. The combined energy climbs to 511 (moderate wave energy), and with that NW wind going dead flat, you’ll be surfing silky lines. This is the pick of the early run – get out there if you can.

After that, we get a bit of a lull through the 26th and 27th, with the swell dropping back and the wind turning cross-on again. The energy stays moderate but the quality drops. It’s a waiting game.

Now, the big news comes on July 28th. Tuesday afternoon delivers a glassy 5ft SW groundswell, with a 14-second period – that’s proper long-period energy. The combined energy hits 962 (moderate wave energy, nearly strong). This is a point-break style swell, so expect long, clean lines and easier paddling between sets. It’s a beauty.

That rolls into Wednesday July 29th morning, still glassy with 5ft WSW swell and 13 seconds of period. The energy is now 1018 (strong wave energy). This is as good as it gets for the whole window. Just be aware that by Wednesday afternoon, the wind swings back to cross-on and the size bumps up to 6ft, which starts to get a bit bony for the groms.

After that, the swell fades through the end of July and into August, with mostly cross-on winds and ordinary conditions. There’s a glimmer on August 4th – Tuesday morning goes glassy again with a solid 5ft SW swell, period 12 seconds, and energy at 731 (moderate wave energy). It’s a long way out, so keep an eye on it, but it’s got the makings of another good session.

August 5th brings the biggest swell of the run – 7ft from the WSW, but it’s cross-on all day. The energy is through the roof at 1363 (strong to very strong wave energy), but with the wind on it, the setup looks more interesting for kite surfing than paddle surfing. Only for the experts if you’re paddling.

So, the standouts are clear: Saturday July 25th afternoon for a clean, fun session, and Tuesday July 28th afternoon for the real deal – long-period groundswell and glass. If you can only pick one, make it the 28th.

This is Rusty, signing off.

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.
