The Lowdown

Alright folks, Rusty here. Let's break down what's on the cards for the next stretch. We're looking at a mixed bag of conditions here at Ferrugem, with a solid, long-period groundswell arriving in the second week that's got me real excited. The water temp is sitting right on average for this time of year at 66°, so nothing unusual there.

The opening days are workable but nothing to write home about. Wednesday the 12th and Thursday the 13th see medium-period SSE swell in the 6 ft to 6 ft range, with moderate wave energy (926 to 1331) and mostly cross-off or light cross-onshore winds, keeping the surf clean enough. The scores are nothing special, but it's a decent start for a paddle.

Friday the 14th and Saturday the 15th are similar, with the swell dropping off a touch on Saturday to 4 ft, but we get clean conditions with NNE cross-off winds. Still, it's not the highlight.

Now, Sunday the 16th and Monday the 17th get a bit messy with the swell turning more east and then northeast, but the winds stay cross-off for the most part, keeping the face clean. The swell energy picks up a bit on Monday (1169 to 1423), but the period is short, so don't expect much push.

Then we hit a flat spell. Tuesday the 18th and Wednesday the 19th are poor, with the swell dropping to 3 ft and 4 ft, and the wind picking up strong from the SSW and NNE, making for lumpy, unappealing surf. Thursday the 20th is a no-go with onshore winds.

Now, here's where it gets interesting. After a quiet Friday the 21st, we get a solid pulse of long-period SSW groundswell starting Saturday the 22nd. The swell is 6 ft to 7 ft, with a period of 12 seconds, and the combined energy jumps up to a strong 1786 to 1806. The winds are light onshore, so it's a bit bumpy, but there's real power in the water.

But the absolute standout is Monday the 24th of August. We've got a 7 ft SSE swell with a very long period of 16 seconds, pushing the combined energy into very strong territory at 2269. The wind is glassy from the NNE in the afternoon, meaning clean, lined-up sets. This is the real deal. This much swell and that long period will be best handled by experienced surfers, as it's going to be powerful and could be a bit much for beginners. It's the kind of day that makes the wait worthwhile.

The rest of the week offers some cleaner, smaller windows with glassy conditions on Wednesday the 26th and Thursday the 27th, but the swell is more modest. Tuesday the 25th is a write-off with onshore wind.

So, to sum it up: the first week is a bit of a grind, but the real gold is waiting for Monday the 24th. Mark that date.

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.
