The Lowdown
Alright, this is Rusty, and I’m looking at the surf over the next couple of weeks for Matanzas.
First thing you need to know: the early part of the week is a bit of a write-off. The swell is there, but it’s messy and the wind is all wrong. We’ve got a couple of days of rain and onshore winds that just don’t want to cooperate. The wait will be worth it though.
The real action starts to fire up on Saturday, August 1st. Saturday morning, the wind goes glassy, and we’ve got a solid 6ft swell rolling in from the SW with a nice 12-second period. The energy is really pumping with a combined energy of 1149, and it’s absolutely clean. This is the best of the early window for experienced surfers. The water is sitting at 55°, which is dead average for this time of year, so nothing unusual there.
The standout session, the one you circle on your calendar, is Friday, August 7th. That morning, the swell jumps to 12ft from the WSW, with a 14-second period and a combined energy reading of 4468. That’s a serious amount of power. The wind is light and offshore from the ESE, making it clean. This is a big, powerful swell – only for experts. The period is long, so the sets will have plenty of punch, perfect for a reef like Matanzas. The Saturday morning after that drops to 8ft, but the wind picks up to 19 mph from the north, making it a lumpy mess, so Friday is your one shot at the big, clean, heavy stuff.
The following Monday, August 10th, offers a return to glassy conditions in the morning with a 5ft SW swell, but it’s not as powerful as the previous week. Still a nice session to have a clean cruise.
Crowds at Matanzas are a possibility, so get in early on those standout days.
Straight up, the best on offer is the big, clean, 12ft swell on Friday, August 7th. If you’re an expert, that’s your day. The Saturday, August 1st is the best for those who aren’t ready for the 10ft-plus stuff.
Rusty out.

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.
