The Lowdown
Alright folks, Rusty here. Let’s have a look at what Hornitos is cooking up over the next couple of weeks.
First thing you gotta know: the water at Hornitos is sitting at 65.3°F, which is a solid 4.7°F warmer than usual for this time of year – that's a big deal. It's like the ocean forgot it’s July. For the next week, the surf is pretty marginal, so don’t expect too much. We get a slow build this coming Tuesday the 28th with chest-high 4.9ft swell from the SW (moderate wave energy at 1078), but the wind is light and cross-onshore, so it’s not going to be clean. The morning of Wednesday the 29th has a touch of onshore wind, but the combo is just not there. The real story is the long period groundswell that creeps in around those days – periods hitting 15 to 16 seconds – which could give some nice lines at the point, but the beach might be too straight and onshore won't help.
Honestly, there is a big gap of nothing happening from now until the end of July. It’s mostly poor or marginal, with the best score only hitting a 2 out of 10. That changes at the start of August. Saturday the 1st of August is your first real standout. The morning kicks off glassy – dead calm, just a slight air – with a clean 3ft swell from the WSW, period of 12 seconds, and energy at 393. It’s not big, but it’ll be clean and fun for an intermediate, and the crowd is only "sometimes" a problem. That's your play for a relaxed, fun session.
Then Sunday the 2nd of August is a repeat: glassy again in the morning, 3.9ft of SW swell (415 energy). If you can sneak out early, you’ll score clean waves.
Looking further out, the ocean starts to pump a bit more. On Tuesday the 4th of August, we see an increase to 6.9ft from the SW, very long period of 15 seconds, and big energy of 1946. That's solid, solid grunt. But the wind is onshore or cross-onshore, and at 6.9ft it’s heading into expert territory. With that long period, the point should handle it better than the beach. It’s a promising but less certain long-range call. Sunday the 9th of August also shows strong 6.9ft SW swell with 15-second periods and energy over 2000, but again, wind is onshore. For experienced surfers, this could be a serious session, but it's far out, so keep an eye on it.
In the second week, keep an eye out for those bigger groundswells – they'll have the grunt, but clean conditions are rare. It looks like mornings are your only hope for a glass-off.
Stay stoked, and don't sleep on that warm 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.
