The Lowdown
Alright folks, Rusty here. Let’s break down the surf for Ferrugem. It’s a bit of a slow start, but we’ve got a few real gems tucked in the middle.
Right now, things are pretty average. You’ve got a swell from the S, around 6 feet, but it’s getting chopped up by a cross-onshore wind at 12 mph, and the period is a short, crumbly 8 seconds. The combined wave energy is 798 (moderate), but it’s all messy. Not worth the paddle. Sunday afternoon is worse, with a bigger 8-foot S swell and an 11-second period, but the same cross-onshore wind at 12 mph makes it too raw and ugly. The combined energy jumps to 1908 (strong), but it’s just a washing machine. Leave it.
Monday, the 10th, is still a pass. The morning has a 7-foot S swell, 12-second period, and a cross-shore wind at 9 mph. The energy is 2255 (strong), but the conditions are just average. By the afternoon, the wind shifts back to cross-onshore at 12 mph, and it’s poor again.
Now, here’s where it gets good. Tuesday morning, the 11th, is a standout. The wind drops to glassy – absolutely dead calm, just a slight air at 3 mph. The swell is a solid 6 feet from the SSE with a nice 12-second period, giving you a combined energy of 1033 (moderate). That’s clean, glassy surf, and for experienced surfers it’s going to be excellent. The wind stays light and offshore through the afternoon, with a cross-off breeze at 3 mph, and the swell holds at 6 feet. It’s going to be a good day.
Wednesday, the 12th, keeps the fun going. The morning is clean with a 6-foot SSE swell, 12-second period, and a light cross-off wind from the N at 9 mph. The energy is 923 (moderate). The afternoon is similar, just a bit smaller at 5 feet, but still very good. Thursday, the 13th, is another real highlight. The morning is glassy again, with a 6-foot SSE swell, a long 14-second period, and a combined energy of 1366 (strong). The longer period means better shaped waves, and it’s going to be clean. The afternoon is offshore with a light breeze, holding the same size. That’s top-tier stuff.
After that, things get a bit iffy. Friday the 14th sees the wind go straight onshore from the SSE, and the swell is around 5 to 6 feet with a 13-second period. The energy is strong (1195 and 1234), but the onshore wind will make it messy. Saturday the 15th has a new 8-foot E swell, but with a short 8-second period – that’s a lot of closeout potential. The wind is cross during the morning and cross-off in the afternoon, so it might be rideable, but not great.
From Sunday the 16th onwards, the swell drops off and the winds are mostly moderate. The 17th (Monday) has a glassy afternoon with a small 5-foot ENE swell, 8-second period, but the energy is low (407). It’s a small, clean wave but nothing to get excited about. The 19th (Wednesday) morning looks decent with a 6-foot ENE swell, 9-second period, and a light cross-off wind, giving a combined energy of 519 (weak). It’s clean, but small.
The final week is pretty quiet. Winds are mixed, and the swell is mostly small (4 to 5 feet) with short periods. The 21st (Friday) morning has a glassy patch with a 5-foot ENE swell, but it’s weak. The 23rd (Sunday) and 24th (Monday) have some small, clean waves, but nothing that’s going to get the heart pumping. The best advice is to lock in those Tuesday, Wednesday, and Thursday sessions from the 11th to the 13th.
Rusty out.

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.
