The Lowdown
G'ay, Rusty here. Right, let's have a proper look at what's comin' our way for the next couple of weeks. It's a bit of a mixed bag, but there's definitely some fun to be had if you're patient.
We're starting off with a solid run of surf from Friday the 17th through to the end of the first week, but the conditions are going to be a bit of a battle. The swell is there, but the wind is mostly a cross-offshore breeze, which isn't the cleanest. The water temp is about average for the time of year, so nothing out of the ordinary there.
Friday the 17th and Saturday the 18th see a NE swell around 6ft to 7ft, but it's a short-period 8-second windswell with moderate wave energy. The wind is a moderate cross-off, so it'll be a bit lumpy. Keep your expectations in check.
Sunday the 19th is much the same, with a 7ft NE swell in the morning dropping to 5ft in the afternoon. The energy is still moderate. A gentle breeze in the morning will be the best of it.
Now, Monday the 20th is where it perks up a bit. The morning glass-off with a light breeze and a 7ft NE swell is looking like the best of the first week. That's a proper window to get out there. The afternoon gets a bit blowy again.
Tuesday the 21st morning is a real gem – glassy conditions with a light NW wind and a 5ft ENE swell. It's small, but it'll be clean as a whistle. The afternoon turns to rubbish with rain and a cross-on wind.
Wednesday the 22nd and Thursday the 23rd are worth a paddle. Wednesday morning, glassy again with a tiny 3ft ENE swell, but Wednesday afternoon picks up a cleaner 3ft S swell with a light cross-off. Thursday the 23rd has a 4ft SSE swell in the morning with a clean cross-off, and the afternoon glass-off with a 4ft SSE swell is a solid call.
Friday the 24th is a write-off with a cross-on wind and a messy 6ft S swell. Just stay home.
The standout of the whole outlook, without a doubt, is Saturday the 25th. Both morning and afternoon are showing glassy conditions with a building SSE swell, 4ft in the morning and the same size in the afternoon. The period jumps to 10 and then 11 seconds, and the energy is solid. This is a proper groundswell, clean and lined up. This is the one to circle on your calendar.
After that, it gets a bit ordinary again. Sunday the 26th is small and clean in the morning, but the afternoon turns to chop. Monday the 27th and Tuesday the 28th are a washout with strong winds and poor surf.
The end of the run, from Wednesday the 29th of July to Saturday the 1st of August, gets interesting again, but it's for expert surfers only. A massive S groundswell fills in, hitting 10ft on Wednesday afternoon with a 12-second period and massive energy. The wind is light and cross-off, making it an excellent call for the experienced crew. But the following days are trashed by heavy rain and strong cross-onshore winds, so you've gotta pick your window. The swell stays big, over 8ft, so it's a heavy-water situation.
So, the best on offer is Saturday the 25th of July. Glassy, clean, and a nice SSE groundswell. That's your day.
Rusty.

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.
