The Lowdown

Alright, Rusty here, breaking it down for you in feet and miles per hour.

It’s a slow start at Hornitos, but there’s a sweet payoff if you’re willing to wait. The water is a balmy 65°F, which is 5°F warmer than normal – feels like you’re surfing in the tropics.

Monday, September 14th kicks off with small, knee-high 2ft swell from the SW. The morning has a light cross-shore breeze, so it’s a bit messy. Not great. Tuesday the 15th is better: the morning is dead glassy, no wind at all, with the swell holding at 3ft from the SW. The period is a long 14 seconds, giving it some real push. It’s clean but small. The wind goes onshore that afternoon and ruins it.

The pattern repeats through Wednesday and Thursday – small SW swell, glassy mornings, onshore afternoons. By the weekend of the 19th, we’re down to tiny 2-2ft waves. There’s a real quiet stretch here.

Now, for the good stuff. From Thursday, September 24th, things start to build. That morning has 3ft WSW swell in glassy conditions. By Friday, September 25th morning, it’s game on. Hornitos gets a clean 5ft swell from the WSW, glassy, with a 13-second period. The wave energy is strong. This is a proper intermediate swell, not too big but with plenty of grunt.

If Friday doesn’t work, Saturday, September 26th morning is another cracker: glassy again with a solid 4ft of WSW swell. The energy is still high. The afternoons get a bit choppy, but those morning windows are pure gold.

Sunday the 27th morning still has clean 4ft surf, but it’s fading. After that, it drops off hard, leaving tiny 1ft leftovers by the 29th. That 20-second period on the 29th will be super long and slow, more of a glide than a wave at a beach break.

So here’s the takeaway: don’t bother with this week. Wait for the mornings of September 25th, 26th, and 27th. Those are your days.

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.
