The Lowdown

Let’s get into it, folks. The first week of this run is going to be a real grind. There's surf, but it's mostly small and it's got that messy, choppy feel to it. The water is a warm 64°, which is a solid 4° above the average for this time of year, so you won't need the thickest rubber.

We're focusing on Hornitos (Peru) for this whole period. The first few days, from August 15th through the 18th, are a write-off. We've got some moderate energy coming through in the 400s and 500s, but the wind is mostly cross-onshore and the wave quality is just poor. It's the kind of surf that makes you question why you bothered.

There's a definite flat spell in the middle, around the 21st to the 24th of August. Swell heights drop to barely 2 to 3 feet, the energy sinks to the low hundreds, and there's just nothing doing. Time to get the fishing gear out or fix the dings.

The good stuff starts to build again near the end of the month. August 28th sees a big jump in size, with a new WSW swell pushing waves well past the 6-foot mark. The energy reading is off the charts at over 2000, so there's some serious power in the water. The wind is light but cross-onshore, which will put a bit of a crumble on the face. This one is strictly for the experienced crew.

But the real standout, the one you should be circling in red, is August 29th. Saturday morning looks good, but it's Saturday afternoon that has my heart racing. The swell is still a solid 5 to 6 feet from the SW with that long, 13-second period, and the wind is forecast to go totally glassy. Clean, powerful, and lined up – that's what we're after. The energy is still strong at 885, but the clean conditions are what will make it special.

After that little peak, it starts to back off into the 30th, with waves settling down to around 4 feet, but the wind swings onshore more, which will chop things up again.

That call for the 28th and 29th is a long-range whisper, so take it with a grain of salt. But if it comes together, the 29th is going to be the day. I'll see you in the water.

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.
