The Lowdown

Righto, let’s have a look at what’s on the cards for the next couple of weeks. My focus is going to be on Triangulo. This spot is a sheltered reef break, tricky ‘cause it’s inconsistent, so we take what we can get.

First off, the water temp here is sitting right around the average for this time of year, so nothing freaky going on with the temp.

Alright, the next 16 days are a bit of a mixed bag. The first few days are a write-off, honestly. We’ve got some small, junky cross-onshore wind and rippled-out surf from Tuesday through to Thursday. Not worth paddling for unless you’re just keen for a splash.

Friday, September 4th, is where it finally gets interesting. The morning is shaping up as the one to aim for. We’ve got a clean 3 ft swell rolling in from the SW, with a light offshore breeze. The swell period is a meaty 16 seconds, giving it proper groundswell grunt – you’ll feel the energy in the water with a combined swell energy of 1354. This is a long-period swell, so at a reef like Triangulo, it’s going to set up nicely, with nice long walls and plenty of power. The wind is light and offshore, which means silky clean faces. For a beginner spot, 3 ft is getting a bit punchy, but if you’re comfortable, it’s the best we’ve got in this window. After that, it drifts back to marginal through the weekend.

After that little burst, the second week turns into a bit of a drought. From Monday the 7th right through to Wednesday the 16th, the swell drops right off and the wind is messy – mostly cross-shore junk. There’s a couple of mornings with clean conditions on the 9th, but with the swell in the 2-3 ft range and moderate wind, it’s still not doing enough. Crowds here are often, so even if the waves are small, expect company.

So, the honest word is: keep your eyes on Friday the 4th, early morning. That’s the standout. The rest of the run is quiet.

Rusty.

Information about the Triangulo Surf forecast

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