The Lowdown

Alright folks, Rusty here. Let’s talk about what’s on offer at Hornitos. We’ve got a run of small, clean windows in the mornings, but you’ll have to be sharp to pick them. The water is sitting at a very warm 66°F, which is much warmer than usual for this time of year, so you can leave the thick wetsuit at home.

The forecast starts with a bit of a flat spell. Tuesday the 8th and Wednesday the 9th are a write-off—onshore breezes and poor conditions. Thursday morning the 10th is the first real glimmer. It’s glassy with a calm wind and a clean 3ft SW swell (14-second period, moderate energy of 326). That’s a nice little window for a grovelly board. The wind goes onshore in the afternoon, so get your session in early.

Friday and Saturday mornings are average at best—small, cross-shore, and only surfable. The real standout comes on Monday morning the 14th. Winds are glassy, the swell is 2ft but it’s a long-period groundswell of 18 seconds, packing a solid moderate energy of 413. That long period means the waves will have shape and push, but at a beach break like Hornitos, it might break a bit straight. Still, for a clean, quiet morning, this is the best of the first week.

Tuesday morning the 15th is another good call—glassy with 3ft of SW swell (14 seconds, 363 energy)—a solid, clean session. The following days are a mix of glassy mornings with small, ordinary waves, but nothing to write home about.

Jumping ahead, the second week looks more promising. Saturday morning the 19th is glassy with 3ft of SW swell, but the energy is dropping. The best bet of the whole outlook is Tuesday morning the 22nd. It’s glassy, 3ft of SW swell with a 12-second period, and a combined energy of 267. It’s a moderate, clean, consistent morning that should offer the best waves of the run. The crowds at Hornitos are *sometimes* an issue, so on a good morning like this, expect a few others out.

The long-range Thursday the 23rd is also glassy with 3ft of SW swell, but energy is weakening. It’s surfable, but not a standout.

Overall, keep your eyes on the mornings. The afternoon wind is almost always a problem, so dawn patrol is your friend. The Monday 14th and Tuesday 22nd are your best bets for clean, fun waves.

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.
