The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s coming up at Hornitos over the next couple of weeks.

The good news is there’s surf pretty much the whole way through, but it’s a real mixed bag of conditions. We’re starting off with a bit of a slow, choppy run, but there are a couple of windows that’ll be worth paddling out for.

First up, Monday the 20th of July. The morning is a bit average with a light cross-onshore breeze on a 4ft swell from the WSW, but the real gem is the afternoon. The wind drops to glassy, the swell cleans up to 4ft, and the water is a touch warmer than normal at 64°. The combined energy is moderate (367). That Monday afternoon window is your best bet for a clean, fun session.

Tuesday the 21st and Wednesday the 22nd are pretty poor. The wind stays cross-onshore, and the waves are a bit wobbly and choppy. Best to give those a miss.

Thursday the 24th of July through to Saturday the 25th are still only marginal. The wind is light cross-onshore, swell sits around 4ft to 4ft, and the energy is moderate (464 to 557). Nothing to get excited about, but you could get a few grovelly ones if you’re keen.

Now, Sunday the 26th of July is another standout. The morning is glassy, with a 2ft swell from the WSW, but the period is a solid 15 seconds – that’s proper groundswell. The energy is moderate (387). It’s small, but it’ll be clean and lined up. Perfect for a longboard or a funboard.

The first week of August kicks off with a pulse of energy. Monday the 27th of July afternoon sees the swell building to 5ft with a 16-second period, and the combined energy is strong (1045). That’s a big, powerful groundswell, but it’s coming straight onshore with a light wind. Not ideal for a peaky beach break, but if you’re a strong paddler and know the spot, it’ll be punchy. Tuesday the 28th of July morning looks similar, with 5ft and 14-second period, energy strong (1096). Still onshore though.

Wednesday the 29th of July and Thursday the 30th of July stay in that 5ft to 5ft range, but the wind is still onshore or cross-onshore, making it messy. The energy stays strong (896 to 944). It’s a bit of a mushburger for paddle surfing, but honestly, with that much wind and swell, this setup might be more interesting for the kite crew.

The end of the run, from Friday the 31st of July to Tuesday the 4th of August, sees the swell drop back to 2ft to 4ft, but the wind remains cross-onshore or even strong cross-onshore (16 mph on the 4th). The energy drops to weak (159 to 262). It’s not looking good for a surf.

Overall, the real standouts are the glassy Monday afternoon on the 20th of July, and the clean, long-period Sunday morning on the 26th of July. The bigger swell windows in late July and early August have the power but the onshore wind spoils the party. Keep an eye on the forecasts, but for now, those two mornings are your best chance for a proper session.

Rusty.

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.
