The Lowdown
Alright, folks, Rusty here, and I’ve got a long look ahead for the Hornitos region. Let me break it down for you straight.
We’ve got a 16-day window starting from the end of July, and honestly, it’s a slow and steady grind rather than a classic pumping session. The first few days are a bit of a write-off, with small, weak swell and tricky cross-onshore winds. The water is sitting at a toasty 66°F, which is a solid 5° warmer than normal for this time of year, so you can leave the thick rubber at home.
The first real whispers of anything worth a paddle come around Monday the 3rd of August. The swell stays small, around 3ft to 3ft, but the wind shifts to an offshore or light cross-on from the WSW, which is a big improvement. The energy is still pretty weak, but the swell period stretches to 12 seconds, giving the waves a bit of shape. It’s marginal, but it’s the first sign of life.
The best bet in this whole outlook is shaping up for Thursday the 6th of August. The biggest day of the period is on the 5th, but the 6th is the standout. You’ve got a solid 5ft of SW groundswell, with a very long period of 16 seconds. That’s proper energy, with a combined energy of 1006 – that’s a solid, chunky number. The wind goes offshore from the WSW in the morning, which means clean, lined-up waves. This is a point-break-friendly swell, so Hornitos should handle it well. It’s a bit too big for beginners, but for the intermediates and above, this is the session to target.
After that, the swell hangs around in the 4ft to 5ft range through to the 11th, with moderate energy and periods mostly in the 10-14 second zone. The wind stays light and often offshore, keeping things tidy. The 11th of August sees another push of 5ft with a 12-second period, but the energy is a step down from the 6th.
By the back half of the second week, from the 13th onward, the swell drops right off, back to 2ft to 4ft, and the wind gets a bit grumpy with a gentle cross-onshore breeze. It’s a poor end to the run, with hardly any push.
So, the clear winner: Thursday the 6th of August. That’s the one you wait for. Clean, strong, and full of potential. The rest is a slow burn of small, clean waves for the patient.
Rusty out.

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.
