The Lowdown

Alright, let me put this in terms you can feel. It’s a slow start, no two ways about it. First decent window comes late, but when it hits, it’s worth the wait.

Sunday the 13th is a write-off – 3ft SW swell with onshore wind and poor conditions. Monday the 14th morning is tiny – 2ft SW, long 18-second period, light cross-shore breeze, but the call is marginal. Not worth suiting up.

Tuesday the 15th morning is the first real chance. Swell is 3ft from the SW, period down to 14 seconds, and it’s glassy – offshore wind from the NW. Clean but small. Combined energy is moderate at 358. Water temp is 65°, much warmer than usual for this time of year, so it’ll feel nice.

Wednesday the 16th morning is glassy again, but swell drops to 3ft, period 13 seconds, energy 241 – just ordinary. Thursday the 17th morning is even smaller at 2ft and energy down to 109. Not worth the drive.

Friday the 18th through Sunday the 20th stays weak. Morning glass-offs but tiny swell and low energy. Tuesday the 22nd morning bumps back to 3ft SW, 10-second period, glassy, but only 126 energy – still ordinary.

Then we hit the good stuff. Friday the 25th morning: 2ft WSW groundswell, 14-second period, glassy, calm wind, energy jumps to 361. Wave comment says expect good surf. That’s your first real standout, but still small.

Saturday the 26th morning is the big one. Swell hits 6ft from the WSW, period 13 seconds, glassy – dead calm – and combined energy is a strong 1024. That’s serious. It’s over 5ft, so beginners should sit this one out, but for intermediates and above, it’s prime. That longer-period groundswell will wrap nicely at Hornitos, a point break setup. Crowds are listed as ‘sometimes’, so expect some company, but it’s worth it.

Sunday the 27th morning holds with 4ft WSW, 12-second period, glassy, energy at 520 – another good session but a step down.

After that, Monday the 28th morning drops to 3ft and ordinary conditions.

So bottom line: the first week is mostly a bust. Target Friday the 25th morning through Sunday the 27th morning. Saturday the 26th morning is the clear winner – biggest swell, glassy, strong energy, and clean conditions. That’s your day.

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.
