The Lowdown

G’day, I’m Rusty. Alright, let’s have a look at what’s coming up for Hornitos. It’s a fairly exposed spot that likes the swell from the SW, and the good news is there’s some swell on the way, but man, the timing with the wind is going to be the real story here. The water’s about average for this time of year, so no need for a thicker wetsuit just yet.

The first real chance to get in the water is looking at Thursday morning, September 10th. It’s only 3 ft of SW swell, but the period is a solid 14 seconds – that’s proper groundswell energy, with a combined energy of 284 (moderate energy). The real kicker? It’s glassy. Not a breath of wind, just glassy conditions. That’s going to be clean as a whistle, but keep in mind with that long period, it might wall up a bit on a beach setup – Hornitos handles it though. That’s your standout window, no question. Thursday arvo the wind swings onshore and it’s gone.

Friday morning the 11th is cross-shore with a light breeze, and the swell drops a little in period, so it’s not looking great. Saturday morning the 12th is back to glassy, but only 2 ft and 12 seconds, combined energy of 212 – surfable but nothing to write home about. Better than the afternoons, that’s for sure.

Sunday and Monday mornings are pretty average, with the wind not playing ball. There’s a glimpse of hope on Tuesday morning the 15th – 3 ft of swell from the WSW, 14-second period, combined energy of 414 (moderate), and glassy wind again. That’s a decent little session if you can sneak it before the afternoon onshore messes it up.

Wednesday the 16th morning is glassy again but only 3 ft and 13 seconds, energy at 240. More of the same. Then there’s a stretch of middling mornings and blown-out afternoons right through to the 21st. Nothing really firing.

Monday the 21st morning is glassy but the swell period drops to 9 seconds – that’s short-period wind swell, combined energy only 148, so it’s small and weak. Tuesday the 22nd morning is glassy again, 3 ft, 11 seconds, energy 221 – better, but still ordinary.

Now, if you can wait, Friday the 25th of September morning looks like the real deal. 3 ft of SW swell but with a 19-second period – that’s a beautiful, long groundswell, and the combined energy is 662 (strong wave energy). Glassy conditions on top of that. That is the standout of the whole run, over two weeks out. Mark it in your calendar, but you know how it goes with long-range forecasts – promising, but keep an eye on it.

Overall, the best on offer is Thursday morning the 10th for that glassy, clean 3 ft SW groundswell, and the long-range standout is Friday morning the 25th. Everything else is just filling in the gaps.

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.
