Alright folks, Rusty here. Let's talk about what's coming down the pipe for Matanzas. We've got a solid run ahead with a mix of some real gems and a fair bit of everyday surf.
The standout session of the whole forecast? That's gotta be Wednesday, July 8th in the early morning. We're looking at a solid 6ft south-west groundswell, and the wind is going glassy, dead calm. That is a recipe for perfection at this reef break, with long-period energy (15 seconds) delivering some serious shape. The swell energy is strong too, clocking in at 1549. If you can get out for a dawn session, this is the one to chase. Just a heads-up, the water is sitting at 53°F, which is about 3°F colder than usual for this time of year, so you'll want a thicker wetsuit. Also, Matanzas can get a few bodies in the water "sometimes," but with conditions that clean, expect some company.
Right now, Monday July 6th morning is also a solid pick. The swell is up at 6ft from the south-west (period 15 seconds) with a clean cross-offshore breeze and very strong energy (1212). It's going to be excellent, but at that height it's leaning toward the experienced crew only. Things get a bit messy in the afternoon as the wind swings onshore and picks up.
From Tuesday through the rest of the week, conditions turn a bit average with cross-shore winds and choppier surfaces. Keep your eyes peeled for Saturday morning, July 11th, there's a little 4ft south-west swell, but it’s battling a cross-breeze so it’s just marginal.
Looking further out, the second week throws down a challenge. On Thursday, July 16th, we get a massive pulse of energy—10ft swell from the south-west with a very long period of 18 seconds, and energy readings over 6000. That is a lot of water moving. But it comes with a cross-onshore wind, making it messy. This kind of long-period swell and big size is strictly for experts only at a reef. The morning of Friday, July 17th still has 8ft swell, but with a strong cross-breeze, it'll be lumpy.
Finally, for the last few days, things settle down. Sunday morning, July 19th, looks like a nice little glass-off with 4ft of clean, weak energy (417) – a good session for a longboard or a fun board. The run fades after that into smaller, punchier west swells with more cross-breeze.
Stay safe out there, and don't sleep on that glassy Wednesday morning.
Rusty.

Information about the Matanzas Surf forecast
The above surf forecast table for Matanzas provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Matanzas can be found by selecting the local surf guide option on the grey menu. Our Matanzas 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 (Matanzas) 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 Matanzas 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.
