The Lowdown

Alright, let’s talk about Hornitos over the next couple weeks. It starts out pretty flat and weak, so don’t get your hopes up for the first week.

There’s a real lull from Tuesday through the 21st. Swell is only 0.5m to 0.8m, and the energy is low – under 200. The mornings have some glassy moments, but the waves are just too small to be worth your time. You’ll see clean surfaces, but it’s not surf, really. More like a lake with a pulse. Afternoons get onshore and choppy, so that’s a wash.

The gap here is nearly a week of underwhelming conditions. You’d be better off doing something else.

Then, around the 22nd, it starts to pick up a little – 0.9m in the morning with glassy conditions. Still small, but a step in the right direction. The energy is moderate, around 150-160.

The standout is at the end of the window – September 25th and 26th. On the 25th, we’ve got 1.1m from the WSW with glassy conditions and energy jumping to 351. The 26th is even better: 1.3m in the morning, still glassy, energy up to 585. That’s the pick of the bunch – clean, building swell, and decent push.

Now, the last couple days, September 29th and 30th, the swell gets bigger – 1.5m to 1.6m – and the energy is strong, over 500-900. But the wind turns cross-onshore and chops it up. It’s got power, but it’s messy. That’s more for the crew who don’t mind a battle. For most, it’s not worth the hassle. This is expert territory.

Water temp on the 15th is about 65°F, which is a bit warmer than usual – like 5°F warmer. That’s a nice surprise.

So, bottom line: wait for the 25th and 26th. Clean, glassy, building WSW swell, and the energy is coming up. That’s your window. Everything before is too weak, and everything after is too messy.

Stay sharp, and you’ll find a couple of good ones.

Rusty out.

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.
