The Lowdown

Alright mate, grab a coffee, because the outlook for Hornitos is a bit of a mixed bag. We’ve got some promising windows, but you’ll need to be patient.
The water is sitting at a balmy 65° , which is about 5° warmer than usual for this time of year – that’s a very unusual warm spell, so you can ditch the steamer for a shorty or just boardshorts.
The first real standout window hits on Tuesday August 11th. We’ve got a solid 4ft SW groundswell pulsing in with a fat 13-second period. The combined swell energy is pumping at a strong 543 . The morning wind looks dicey, but the Tuesday afternoon window shows a light breeze from the SW at 6 mph . It’s cross-on, but with that energy and long period, Hornitos is your best bet for a proper wave. It’s an intermediate spot, and it’s consistent and fairly exposed to the SW, which is spot-on for the swell direction. Just be aware it can get crowded sometimes.
After that, the surf drops right off. We go through a long, flat run from Wednesday the 12th right through until Tuesday the 18th. The waves are tiny, mostly under 3ft , and the conditions are just ordinary – light cross-onshore winds and generally poor, unsurfable slop. It’s not a good look.
Things pick up again on Tuesday afternoon August 18th. A nice bump of 5ft SW swell rolls in with a 13-second period, and the combined energy cranks up to 695 . The wind is light and *on* from the WSW at 6 mph . That’s a clean lineup for a session if the tide plays ball. This is your other real standout for the whole period.
We then get another lull. The rest of the week is a washout until Saturday afternoon August 22nd. The swell is small at 2ft , but the wind goes completely *glassy* and dead calm. It’s not going to be big, but for a longboard or a foiler, it’ll be a glassy, clean, and super fun session. The combined energy is weak at 97 , so don’t expect power.
After that, the whole second week looks small and inconsistent. There’s a brief window on Monday morning August 24th with 2ft SSW swell under glassy conditions, which is worth a look for a clean small-wave paddle. The energy is only 167 though.
Overall, the best bets are Tuesday August 11th afternoon for a proper swell with some grunt, and Tuesday August 18th afternoon for the best-sized waves in the whole forecast. Get on it.

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.
