The Lowdown
G'day, Rusty here. Let's have a look at what's coming up at Ferrugem.
The next couple of days are pretty grim, so we've got a bit of a wait on our hands. The surf kicks off properly on Monday the 7th, but it's nothing to write home about. Monday morning's offering is a bit of a mixed bag with a 5ft S swell at 10 seconds, but the wind is a light cross-shore, so it's clean but small and weak. The energy is pretty average at 514, so you'll be fighting for scraps. After that, the week builds nicely. The standout is looking like Wednesday the 9th, especially the morning session. We've got a 5ft ENE swell, but the period is short at 8 seconds, so it won't be a groundswell. The wind is a slight offshore from the N at 3 mph, so the conditions will be clean and glassy. The combined swell energy is a solid 584, and the break is very consistent, so there'll be plenty of waves to go around. It's an intermediate spot, so it's not one for the groms, but it's not crazy either. The water temp is 65°F, which is about average for this time of year.
Tuesday the 8th has a similar story, with a 4ft SSE swell and a light offshore from the N, but the energy is a bit lower at 329. It's still clean, but smaller. Thursday the 10th is a write-off with a 3ft SSE swell, but a very long 15 second period - that'll be straight and hard to manage at a sandbar. Friday the 11th has a 3ft E swell, clean with a light offshore, but it's small. Saturday the 12th morning is clean again with a 5ft SSE swell, but by the afternoon it gets messy with a 8ft SE swell and cross-onshore wind - that one's for experts only, if anyone at all.
The following week gets a bit more interesting. Monday the 14th sees a 8ft SE swell in the afternoon with a clean offshore from the N and a huge 1528 energy reading - that's proper strong. The period is 10 seconds, so it's a decent groundswell, but at that size it's expert territory. Wednesday the 16th is poor with onshore winds, so don't bother. Friday the 18th is tiny, with a 2ft E swell but completely glassy conditions - you'd need a log for that.
The real long-range standout is Saturday the 19th morning. A 6ft SSE swell with a very long 15 second period, clean offshore from the NNE at 12 mph, and a massive 1547 combined energy. That's a proper groundswell and it's going to be cranking. The long period means it'll be better at a point or reef, but Ferrugem is a sandbar, so it might break a bit straight. Still, it's the best on offer for the whole 16 days, but it's a long way out so don't book your flights just yet. After that, Sunday the 20th drops off quickly and Monday the 21st is small and weak again.
So, to sum up: Wednesday the 9th morning is the pick of the first week, and Saturday the 19th morning is the big one to watch in the second week. Keep an eye on the forecast.

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.
