Table - best surf conditions forecast for Hornitos over the next 16 days.
Alright folks, it’s Rusty here. Let’s take a look at the stretch ahead for our local waves.
Look, I’m not gonna sugarcoat it. The next week or so is a real mixed bag of a window. We’ve got some solid energy coming through, but you’re gonna have to pick your moments to get the clean ones. The water is sitting right around 62°, which is bang on average for this time of the year, so no surprises there.
We start off on Sunday the 12th with small, weak stuff. A few tiny 3ft to 3ft swells from the SSW with a decent 14 to 16-second period, so there’s a bit of push behind them. The issue is the conditions: Sunday morning is borderline, but Sunday afternoon? That’s where it gets interesting. Glassy wind, clean lines, real surfable. It’s small, but if you’re on a log or a fish, it’ll be a laugh. The energy is moderate (431) so don’t expect any powerhouses.
Monday the 13th is flat and messy. Leave the board in the car.
Now, Tuesday the 14th. This is the standout window for the whole first half. We’ve got the swell bumping up to 4ft to 5ft from the WSW and SW, still with a nice long 14 to 15-second period. But the real kicker is the wind: glassy, absolute perfection. The combined energy jumps to 804, which is a solid moderate punch. This is clean, proper surf for the intermediate crowd. Hornitos will be working its magic with that solid SW groundswell. Crowds are *sometimes* an issue, but on a Tuesday? You’ll be sweet.
Wednesday the 15th and Thursday the 16th see the quality drop off thanks to cross-onshore breezes messing up the face. Size is still there (3ft to 4ft) but it’s not worth paddling out unless you’re desperate. Friday the 17th is a write-off with tiny 2ft to 2ft dribble.
Saturday the 18th has a late afternoon glass-off saving grace. By 4pm, the westerly dies, and a 5ft WSW groundswell (period 11 sec) cleans right up. Energy is still strong (658) for the size. That’s your second-best call if you miss Tuesday.
Sunday the 19th is also looking promising in the afternoon. Another 5ft WSW groundswell, 12-second period, and glassy wind expected. The energy is right up there at 762. Very good conditions. This one is a serious option for a weekend session.
Into the second week, Monday the 20th gets a jump in size – 7ft from the SW by the afternoon, but the wind swings cross-onshore from the SW at 9 mph. That bumps the energy to a very strong 1553, but the chop will be serious. This is getting into expert territory size-wise (over 8ft in the morning) and the wind is messy. Honestly, that afternoon is looking more like a kite-surfing setup than a clean paddle session. Tuesday the 21st stays big (6ft to 7ft) but the wind remains lively and cross-onshore.
From Wednesday the 22nd right through to the 27th, it’s a slow slide into average conditions. Swell drops back under 5ft, the period shortens up, and the wind just won’t cooperate. There are a few moments of clean-ish looking conditions on the 24th and 26th, but nothing will top that Tuesday the 14th or Sunday the 19th. Energy values drop below 600 for most of this period, and the water temp will stay about average.
Bottom line: The best waves in the whole 16 days are Tuesday the 14th (afternoon) and Sunday the 19th (afternoon). Both offer glassy conditions, chest to head-high swell from the optimum SW direction, and moderate to strong energy. Lock those in and ignore the rest.
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.
