Table - best surf conditions forecast for Hornitos over the next 16 days.
Alright, Rusty here. Let’s have a look at what’s on the cards.
First off, the water temp is sittin’ at 62°, which is about average for this time of year—nothing weird going on there.
To be straight with you, the next 16 days are a mixed bag. The first proper surf worth paddling out for doesn’t show up until Saturday the 12th. Before that, there’s a gap with nothing really worth mentioning.
Kicking off on Saturday the 12th, Hornitos has small 3ft SSW swell with a long 16 second period. That’s proper groundswell energy, and with glassy conditions in the morning, it’ll be clean. The combined energy is 364 – moderate. It’s not big, but it’s clean and consistent. For an intermediate, that’s a nice little session.
Sunday the 13th keeps the same vibe – another 3ft SSW swell, glassy in the morning, period dropping to 14 seconds. Similar energy (337). Still clean, still small. Good for a longboard or a fun board.
Now, Tuesday the 15th afternoon is where we get a standout. That 5ft WSW swell with a 14 second period and glassy wind? That’s gonna be the pick of the first week. Combined energy is 717 – solid moderate. Clean conditions and a bit more push. Hornitos will be turning on.
Then things get a bit ropey through the middle of the week with onshore winds and messy conditions. There’s a bit of a lull.
But hold on – Saturday the 19th afternoon sees 5ft WSW swell, 11 second period, glassy again. Energy at 529, moderate. That’s another clean window but still small enough for most.
Sunday the 20th morning gets chunky – 7ft WSW swell, 13 seconds, but it’s cross-on with a light breeze. Energy jumps to 1492 – strong. That’s expert territory for size, and the wind isn’t perfect, but the power is there.
The real beast shows up on Tuesday the 22nd morning. 12ft WSW swell, 16 second period, combined energy a massive 5957 – very strong. Problem is, that’s way too big for Hornitos. Only for the absolute pros, and even then the cross-on wind (9 mph) makes it a mess. Afternoon sees 16 mph cross-on – that’s kite-surfing conditions, not paddle surfing.
After that, it drops back down through the end of the month with smaller, less consistent waves and mostly cross-on winds. Nothing to get excited about.
So, the standout overall is Tuesday the 15th afternoon – 5ft WSW, glassy, clean, good energy. If you can only pick one session, that’s it. The second shout is Saturday the 12th morning for a clean, small but long-period groundswell.
Keep an eye on the big Sunday the 20th morning if you’re a charger, but that’s for experts only.
Cheers,
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.
