The Lowdown

Alright folks, Rusty here. Let's have a look at what's cookin' for Hornitos. It's a quiet start, so don't rush down there just yet.

We're looking at a pretty flat spell to kick things off. From Saturday the 22nd right through until Thursday the 27th of August, it's a write-off. The swell is tiny, mostly around 1.3ft to 2.6ft, with weak energy readings down in the double digits (97, 60, 32). The winds are mostly onshore or cross-onshore, so it's going to be messy and small. Not worth wetting a suit for.

Things start to perk up a touch on the 28th of August. A solid pulse of SW groundswell pushes in, but it's a double-edged sword. Friday morning the 28th brings a solid 7.2ft of SW swell at a very long 15 seconds, with moderate energy (2175). This is big, powerful stuff. For an intermediate spot like Hornitos, that's getting into the "experts only" zone. The wind is onshore in the morning, so it's going to be a battle. The afternoon cleans up a little, but it's still a cross-onshore breeze. The surf quality is marginal at best, more of a big, churning mess than a clean, rideable wave.

The weekend of the 29th and 30th sees the swell drop back a bit, but it's still a chunky 4.9ft to 5.6ft, mostly from the WSW. The wind stays cross-onshore, so it's going to be choppy and bumpy. The energy is still there, but it's not going to be pretty. By the 31st, the swell is all over the place, with a short period and a moderate breeze making it a bit of a washing machine.

Now, the highlight of the whole run, and it's a long way out, so take it with a grain of salt. Around Wednesday the 2nd of September, we see a potential gem. The morning has a 3.9ft SW swell, but the real story is Wednesday afternoon. The wind goes glassy with a WSW onshore that's so light it's almost nothing. That's a huge plus. The swell is only 2.6ft, but it's coming from the WSW with a very long 20-second period. That's a proper groundswell. The energy is moderate (833). This setup is best for a point or reef, but at Hornitos, a beach break, that long period might make it a bit too straight. But with glassy conditions and a clean face, it could be a fun, small-wave session for the skilled surfer.

Thursday the 3rd of September keeps that long-period energy going with a 4.3ft to 5.2ft SW groundswell at 18 seconds and strong energy (1351 to 1518). The wind is light onshore or cross-onshore, but the quality is still marginal. The water is still quite warm for this time of year, running about 2.6° warmer than average, so you can leave the winter rubber at home.

The window closes again after that, with the swell fading and the wind picking up to a moderate cross-onshore breeze for the second week. It's a classic case of a few promising days in a long, flat window. The standout is that Wednesday the 2nd of September afternoon with the glassy conditions, even if it's tiny. Friday the 28th of August has the size, but the conditions are rough. If you're a confident surfer who can handle big, mushy onshore surf, maybe Friday the 28th is your jam, but for clean lines, wait for the 2nd of September.

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.
