The Lowdown
Alright folks, Rusty here. Let’s have a good look at what’s coming up for the next couple of weeks at Ferrugem. It’s a bit of a mixed bag, so we gotta pick our moments.
The first week or so is pretty average. We’ve got small, weak swell and the wind is mostly cross-off from the north, which keeps the surface clean but doesn't do much for the wave quality. The real action starts to build towards the end of the second week and into the start of the following one.
Looking at the whole period, the standout window is definitely the morning of Saturday the 18th. That’s when we see the biggest pulse of the forecast, with a 7ft NE swell pushing through. The combined energy is a solid 1097 (moderate wave energy), so there’s some grunt in the water. The wind is cross-off from the NNE at 12 mph, so the surface will be clean. This is a good, solid intermediate swell, but at 7ft it’s getting a bit full-on for beginners. The period is short at 8 seconds, so it’ll be a bit of a lumpy, sectiony wave, but the size alone makes it the best on offer.
Another one to circle is the morning of Thursday the 23rd. The swell drops back to 5ft from the ENE, but the wind is a lighter cross-off from the NNE at 9 mph, and the forecast says "expect very good surf conditions". The combined energy is 645 (moderate wave energy), so it’s got some push without being a handful. This one would be a cleaner, more fun wave for the average surfer than the bigger Saturday.
The rest of the time is a struggle. There are a few days like Sunday the 19th afternoon where we get a glassy 5ft ENE swell, but the energy is low (322) and the surf is weak. There’s a long gap of poor conditions from the 20th through to the 22nd, then a few decent mornings, before another patch of weak, messy surf from the 25th to the 29th.
The water temp is about average for the time of year, nothing out of the ordinary.
So, for the best waves, set your alarm for the morning of Saturday the 18th for the biggest swell, or the morning of Thursday the 23rd for the cleaner, more manageable session. The 30th of July morning is worth a mention too – a 8ft NE swell with light wind, but it's a long way out and the wind is slightly onshore, so it’s a promising maybe.
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.
