The Lowdown
Alright, Rusty here. Let's talk about what's coming up for Matanzas.
First off, the water temp is sitting at about 54°, which is a bit colder than what we're used to for this time of year. Might want an extra layer, but it's not gonna keep you out of the water.
Honestly, the next week or so is a bit of a letdown. We've got a few days of marginal conditions and a lot of lumpy, choppy wind. It's not until Thursday the 23rd that things really pop off. That morning, the forecast is for a solid 12 ft SW groundswell at 13 seconds, with the combined energy hitting a massive 3784. That's a proper pulse of energy. And the wind? Glassy. Absolutely glassy. This is going to be a day for the experienced crew only – that's well over 8 ft, so leave the foamies at home. The optimum direction from the southwest lines up with the swell direction, making it a quality window.
That following Friday morning, the 24th, is still looking very strong. We've got a 7 ft SW swell (combined energy 1005) and a clean offshore breeze from the SSE. Another excellent session for those who know what they're doing.
For the rest of the forecast, there are glimpses of rideable surf, like Sunday the 26th afternoon with a 4 ft W groundswell and a cross-offshore breeze, but nothing that really steals the show compared to that Thursday stand-out. The period into the end of July looks pretty messy with onshore winds and storm risks, keeping the surf poor to marginal. It's a classic case of waiting for that one good window.
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.
