The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s shaping up for Hornitos over the next couple of weeks.

We’ve got a bit of a slow start, but the first real chance to get wet arrives on Friday, July 17th. The afternoon sees a clean 4ft southwest swell rolling in with an 11-second period, and the wind is glassy out of the west-southwest at just 3 mph. The water is sitting at 63°, which is a touch warmer than normal for this time of year. The combined energy is solid at 409 (moderate energy), and honestly, conditions are set to be pretty good. This is a standout early window, so if you can sneak out Friday arvo, do it.

Saturday the 18th offers a bit of a mixed bag. The morning is a bit questionable with tide concerns, but the afternoon clears up nicely with the same 4ft, 10-second swell from the WSW and glassy 3 mph offshore winds. It’s surfable, but not as crisp as Friday.

Sunday the 19th is a write-off. The swell bumps up to 5ft with a longer 12-second period, but the wind turns cross-onshore out of the north-northwest at 6 mph, and the conditions are reported as poor. Not worth paddling out.

The start of the next week (July 20th–22nd) is nothing special. We’ve got knee-to-waist high waves, but the wind is mostly cross-onshore or onshore, and the combined energy dips into the 320–428 range. The surf is marginal, and the quality just isn’t there.

Things start to look more interesting on Wednesday, July 22nd, with the afternoon swell picking up to 5ft from the southwest, with an 11-second period. The combined energy jumps to 718 (moderate to strong), but the wind is still cross-onshore at 6 mph, so it’s a bit bumpy. Still, that’s a solid amount of water moving.

Now, keep your eyes on the prize for Wednesday, July 29th. This is the real standout of the whole outlook. The morning brings a clean 5ft southwest swell with a 13-second period, glassy winds out of the north at 3 mph, and the combined energy is a hefty 915 (strong wave energy). The afternoon is just as good with the same swell and glassy conditions from the southwest. This is proper, clean, long-period groundswell. For a spot like Hornitos, which is fairly exposed to the southwest, this is going to line up nicely. The only thing to note is that with a 13-second period, the sets will have some punch and gaps between them, but it’s going to be worth the wait. The crowd is noted as sometimes being around, so you might have some company for these waves.

After that, the last few days of July and into August look like a slow fade. The swell drops back to 3ft–4ft, and while there are a few glassy moments on the 30th and 31st, the energy is weak. By August 1st, the wind picks up and the conditions turn poor, so that’s the end of the run.

So, to wrap it up: Friday the 17th is your early call for a glassy, clean session. But the absolute best of the bunch is Wednesday, July 29th, with that 5ft southwest groundswell and glassy conditions. That’s the one to circle on the calendar. Beyond that, the second week is slim pickings, with only a few brief moments of clean surf.

Stay stoked, and I’ll see you out there.

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.
