The Lowdown

G'day, I'm Rusty, and here's the outlook for the next couple of weeks. We're looking at a mixed bag, but there's some real gold to be found if you're patient.

The run starts on Tuesday the 18th of August at Ferrugem, a sandbar setup that's very consistent. The water's sitting at 66°, which is pretty much bang on average for this time of year, so nothing to worry about there. The morning sees a 5ft swell wrapping in from the ENE, with a short 8-second period, so it's a bit of a windswell, not a lot of power behind it. The wind is a gentle cross-off from the north, keeping the surface clean. The combined energy is moderate, at 298. It's a decent, surfable morning, but not a standout. The afternoon holds similar, with a slightly smaller 5ft swell.

Wednesday the 19th is a write-off with a cross-on wind, and the swell drops to 3ft. Thursday the 20th is not much better, with a small 3ft to 3ft swell and a messy wind. Friday the 21st is more of the same—small and weak, with combined energy down to just 92. We're in a lull, folks.

Then things get interesting. Saturday the 22nd of August, the swell kicks up with a 7ft southerly swell, period 9 seconds. The combined energy jumps to a strong 1206. But the wind is a moderate cross-shore, making it a bit of a battle. This is a big, powerful wave, so it's getting into the territory for experienced surfers only. The morning is marginal, and the afternoon turns into a choppy mess.

Sunday the 23rd is a step in the right direction. The swell holds at 6ft, still from the south, but the period stretches to 11 seconds, giving it more push and better shape. The morning is clear with a light cross-shore breeze, and the combined energy is a solid 674. It's still a bit on the big side, but the conditions are improving. The afternoon turns onshore, so the morning is the pick.

Now, here's the one you've been waiting for. Monday the 24th of August is the true standout. Ferrugem gets a 8ft swell from the SSE, with a long 14-second period. The combined energy is a massive 2408. This is a serious groundswell, full of energy, and it will be a freight train. The morning is clear, with a light cross-shore wind. This is a big, powerful, clean swell—expert territory only. The afternoon stays strong at 8ft. If you're an experienced surfer, this is your session.

Tuesday the 25th is still solid, with a 6ft SSE swell and a 12-second period, but the wind picks up to a fresh cross-off, keeping it clean. The energy drops to 836. It's still good, but the peak has passed.

The following week offers some smaller, cleaner windows. Wednesday the 26th has a 4ft SSE swell with a 11-second period and a light offshore from the NW in the morning. That's a nice, clean, smaller groundswell, perfect for a log. The 28th of August, a Friday morning, is glassy with a 4ft NE swell, and the 29th is also glassy with a 5ft SSW swell. The 30th and 31st see more rain and onshore winds, but the swell stays around 5ft to 7ft. The window closes on the 1st and 2nd of September with small, poor waves.

So, the pick of the litter is absolutely Monday the 24th of August. That's a big, clean, groundswell at Ferrugem. The 26th and 28th are your smaller, cleaner options for the rest of the crew.

Stay safe, read the conditions, and I'll see you in the water.

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.
