The Lowdown
Alright, Rusty here. Let’s talk about the next couple of weeks at Hornitos.
We’ve got a slow burn to start. Friday morning shows a 4ft SW groundswell with glassy offshore winds out of the WNW at 3 mph – that’s clean. The water is 65°, a solid 4° warmer than normal, so it’s a treat. The combined swell energy is moderate at 633, but they’re calling it marginal with questionable tide. Friday afternoon goes sour with 9 mph cross-onshore winds, so get out early.
Saturday and Sunday are a mess. Light cross-onshore winds and short-period swell from 4ft to 4ft are just choppy. Sunday morning shows a 4ft, 14-second period groundswell with energy at 684, but the wind barely holds offshore and it’s still marginal. Monday bumps up to 5ft with strong energy at 1011, but the wind is onshore and messy. That 5ft Monday afternoon with a 15-second period and cross-shore wind is big enough for intermediates, but it’s choppy.
Now, Tuesday the 11th of August is your spot. Tuesday morning brings a clean, cross-offshore breeze from the SSE at 3 mph, with a 5ft SW swell and a 13-second period. The energy is moderate at 642, but the wind is right. That’s your best shot for clean waves. After that, the week drops off with building cross-onshore winds and shrinking swell.
The second week is a slog. The swell hangs between 2ft and 4ft, but it’s almost always onshore or cross-onshore. The 18-second period on Thursday the 13th is a long-period groundswell, but at only 3ft, it won’t do much at a beach break like Hornitos – you’d want a point or reef for that. Saturday the 22nd of August gives a rare moment of glass, with 3ft SW swell and an 11-second period, but the energy is a weak 245. It’s surfable, but just barely.
If you’re keen, hit Tuesday morning. Otherwise, the second week is a waiting game. Forecasts can flip, but for now, it’s a lot of marginal.

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.
