The Lowdown

Hey, Rusty here, and I’m looking at the same stretch for the next couple weeks. Honestly, it’s a slow period, no getting around it. Long stretches of flat or junk, with just a couple windows where you might get a clean wave.

The 12th and 13th are a write-off—small swell, crappy cross/onshore wind. Don’t bother.

Monday the 14th morning turns it around a bit at Hornitos. We get groundswell from the SW at about 2ft, but the period is long—18 seconds. The combined energy is moderate (444). The wind is glassy, dead calm. It’ll be clean. At that period, the waves will have shape and push, but on a beach break they’ll break a little straight. Still, with warm water—about 67°F, which is way warmer than usual for mid-September—it’s a pleasant paddle. Beginners could handle this size no problem.

Tuesday the 15th morning is probably the pick of the whole run. Glassy conditions again, with 3ft SW swell at a very long 14 seconds. Energy is moderate (360). Clean, lined-up waves, though again, the period is long enough that a point break would be better. For here, it’s the most fun you’ll get in this forecast.

After that, it’s a rinse and repeat of glassy mornings with small 2–3ft swell, but the comments keep saying “ordinary” or “surfable but very ordinary.” The afternoons get ruined by onshore wind. The energy drops into the low 100s (136–218), which is weak.

From Wednesday the 23rd to the end, the swell gets tiny—down to 2ft or so—and the energy drops into double digits (57–184). Only a few glassy mornings, but nothing to get stoked about.

Your best bet? Monday the 14th and Tuesday the 15th mornings. Get out there early for the cleanest, longest-period SW groundswell. It’s not firing, but it’s the best surf in this whole outlook.

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.
