The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s cooking for our local stretch.

The next few days are a bit of a write-off, I gotta be honest. There’s a real gap in quality surf until we get to next week. Wind and swell just aren’t playing ball. We’ve got some solid energy showing up on Saturday the 12th, and then again mid-next week, but patience is the name of the game.

Barrinha is the only break in the game for us. The water temp is sitting at 63°, which is a bit colder than we’d usually expect for this time of year—nothing crazy, but you’ll want a decent spring suit.

The first real glimmer of hope is Saturday morning, September 12th. Swell jumps up to 8ft from the SW with a moderate cross-offshore breeze of 15 mph, keeping things clean. The combined swell energy is strong at 1286. That afternoon picks up even more grunt, hitting 2204 on the energy scale, same 8ft SW swell. This is a powerful, clean lump. But at 8ft, this is one for experienced surfers only—beginners should sit this one out. The period is only 10 seconds, so it’s a bit of a windswell, not the cleanest groundswell, but the shape should be rideable.

After that, Sunday and Monday are a mess with onshore winds and rain. The next standout is Tuesday morning, September 15th. Glassy clean water, 3 mph SSW cross-offshore breeze, and 4ft of S swell at 11 seconds. The energy is moderate at 434. It’s not huge, but the conditions will be sweet—a good, clean session for intermediate folks.

Then we get a proper pulse. Wednesday afternoon, September 16th is the big one. We’ve got an 12ft S swell, 13-second period—that’s a long period groundswell, full of power. The energy reading is massive at 6411. The wind is a clean cross-offshore from the S at 15 mph. Now, a heads up: the forecast says the swell might be too big for this break. At 12ft, this is expert-only territory. It’s going to be a big, powerful, clean day, but only if you’re really on your game. This is the standout of the whole outlook.

Thursday morning, September 17th is a gem too. 7ft S swell at 12 seconds, but the wind is glassy—NNE at 3 mph. Absolutely dead calm, clean as a whistle. Energy is strong at 1122. This is the best pick for most surfers. It’s got size, power, and perfect conditions. A morning session here is going to be magic.

The rest of the period into the third week sees some smaller pulses, but the wind and swell are mixed. There’s a brief clean moment on Tuesday, September 22nd with 3ft S swell at a very long 14 seconds, clean and light winds, but it’s small—more of a longboard or funboard kind of morning.

So to round it up: the early days are a bust. Saturday the 12th is for the experienced crew only, but Thursday morning the 17th is your top pick for a clean, powerful, glassy session. And if you’re a lifer looking for a beast, Wednesday afternoon the 16th has the biggest, cleanest swell, but it’s for experts only.

Rusty out.

Information about the Barrinha Surf forecast

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