The Lowdown

Right then, let’s have a look at what’s cooking for Ferrugem. This sandbar setup is exposed to the swell and Northwest winds are the ticket for clean conditions. The water temp is about average for this time of year, so nothing wild there.

Honestly, the next few days are a bit of a struggle. Friday the 4th and Saturday the 5th are pretty much a write-off with cross-onshore winds chopping up small, weak swell. Combined energy is only 181 and 265, so there’s just not enough push to work with.

We start to see a pulse of energy on Sunday the 6th, with swell building to 6ft from the S on the morning, climbing to 8ft from the S in the afternoon, but the wind is a cross-shore fresh breeze. The combined energy jumps to 1048, so there’s power there, but it’s lumpy and messy. Monday the 7th is a bit better with 6ft from the SSE and lighter cross-shore winds, bringing the energy down to 556. It’s still just marginal though.

Now, Tuesday the 8th is where it starts to turn. Morning brings a clean 5ft swell from the SSE with light cross-offshore winds. Combined energy is 532 and it’s looking tidy. That’s a decent window for an intermediate session.

The standout, without a doubt, is Wednesday the 9th morning. We’ve got a 7ft swell from the NE, clean with gentle cross-offshore winds, and the combined energy is a solid 1069. That’s proper wave energy. This is excellent for experienced surfers—it’s a bit much for beginners at that size. The period is a short 8 seconds, so it’ll be a bit punchy and sectiony, but the power is real.

Thursday the 10th keeps the run going. Morning has a clean 6ft from the E with cross-offshore breeze, energy at 529. Then Thursday afternoon goes glassy with a 5ft E swell and calm winds. That’s a beautiful looking session for a sunset paddle.

Friday the 11th morning is glassy again with 5ft from the ENE, energy at 479. Nice and clean. After that, things get a bit messy again through the weekend with onshore winds and dropping swell.

Looking into the second week, Monday the 14th has some potential with clean 6ft and 8ft E swells in the morning and afternoon, but the wind is cross-offshore and moderate. The energy on the afternoon hits 1937, which is very strong, but that 8ft is only for the crew who know what they’re doing. Tuesday the 15th is a bit smaller at 7ft from the E but with light cross-onshore bumps.

The real long-range promise is Wednesday the 16th morning, with a 6ft S swell and light cross-onshore, energy at 1260. That could be fun if the wind plays ball. After that, the swell fades away into small, weak stuff by the end of the window.

Overall, the best bet is Wednesday morning the 9th for the biggest, cleanest power, and Thursday afternoon the 10th for a glassy, user-friendly session. Get on it.

Information about the Ferrugem Surf forecast

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