The Lowdown
Alright, Rusty here, let's break down what's coming up in the next couple of weeks.
We're starting off a bit slow. From Thursday, July 23rd through Sunday, July 27th, the surf is pretty flat and messy. We've got some swell in the water, but the wind is mostly cross-onshore, keeping things choppy and poor. The best we see is a quick window on Saturday afternoon, July 25th, when the wind goes glassy, and the swell is 4 feet from the WSW with an 11-second period. It's clean, but it's not going to blow your mind. The water is a touch warmer than normal at 64°F.
Now, the real standout is Tuesday, July 28th. Tuesday morning, we're looking at a 5-foot swell from the SW with a 14-second period, and the combined energy is strong at 1174. That's a lot of power. The wind is glassy, and the forecast is for very good surf. This is the session to circle on your calendar. Hornitos is fairly exposed to the SW swell, so it'll be working. That long period (14 seconds) means it's a proper groundswell, which can be a bit straight at some beach breaks, but the quality should be there.
After that, we're in for a long stretch of marginal to poor conditions from July 29th through August 4th. There's some swell, but the wind is mostly cross-on, and the energy is moderate. It's a bit of a lull.
Then, on Wednesday, August 5th, we get another spike. The swell jumps to 7 feet from the SW with a 14-second period, and the combined energy is very strong at 1560. This is a powerful, solid swell, but it's a long way out. The forecast is marginal, but with that energy, if the wind behaves, it could be a cracker. At 7 feet, it's a bit much for beginners and best left for the experienced crew. The days after, August 6th and 7th, still have some 5-foot swell hanging around, but the wind is a little cross-on, so it's not the main event.
So, the two best bets: Tuesday morning, July 28th for the glassy conditions and solid groundswell, and Wednesday, August 5th, for the biggest, most powerful swell of the period, though that one's a long-range promise.
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.
