The Lowdown

Alright, crew, Rusty here again. Let's break down the Roca Alta forecast in feet and miles per hour.

Honestly, it's a pretty tough run for the next two weeks. The swell is coming from the ENE, and this spot really wants it from the NE to get the best shape. The wave energy is moderate, hitting around 130 to 151 (combined energy) on the first day, so it's not a total flat spell, but the conditions are a real mess. The wind is mostly cross-onshore, chopping it up, and the period is a short 8 seconds, so it's weak, wind-driven junk.

The first week is a real slog. Tuesday the 8th has a small 3ft to 4ft ENE swell, but with a cross-on breeze most of the day, it's messy. The swell builds slightly through Thursday the 10th, hitting 6ft, but the wind stays cross-onshore, making it a real battle. Friday the 11th through Sunday the 13th are similar – small, crossed-up waves in the 4ft to 5ft range with onshore influences. There's a bit more energy, hitting 678 (combined energy) on Thursday morning, but the quality is just not there. It's the kind of stretch where you're better off sitting it out.

There is one bright spot, though. On Tuesday the 15th, the early morning is looking like a winner. We get a glassy 5ft ENE swell with light winds out of the NNW. This is your best bet in the near term. The wave energy is solid at 389 (combined energy), and with that glassy surface, the waves will be clean and lined up, even if the direction isn't ideal. It's a proper window for a session. Just remember, this is a reef break for advanced surfers, and it can get crowded sometimes, so don't sleep in.

After that, it's back to the same old story until we hit the end of the forecast. The weekend of the 19th and 20th of September has some promise, with glassy conditions on Saturday morning and afternoon, and again on Sunday morning. The swell is small, only 3ft to 4ft, and the period is short, but the wind will be off the water. For a long-range call, it's a promising window for a clean, fun-sized wave, but it's a week and a half out, so keep an eye on it.

The final days of the timeline see the swell drop off into the 3ft range and below, with the energy dropping to just 48 (combined energy) by the 23rd. It's basically a flat spell, so don't hold your breath.

So, the standout is Tuesday the 15th morning for the best combination of size and clean conditions. The Saturday and Sunday of the 19th and 20th are a more distant, smaller alternative. For the rest of it, it's a waiting game and the conditions are poor.

Rusty.

Information about the Roca Alta Surf forecast

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