The Lowdown
Alright, let’s switch over to feet and miles per hour.
Right off the bat, I’ll be straight with you – for the next couple of days, it’s a bit of a write-off. Saturday and Sunday are looking pretty average, with small, short-period swell and onshore or cross-shore breezes messing things up. You’d be fighting a cross-chop for tiny waves. Not worth paddling out for.
Things start to turn around on Monday morning (September 7th). We’ve got a bit of a bump in energy with a combined swell energy of 539 (moderate) and 6 ft swell out of the SSE. The wind is light and cross-offshore, keeping things clean. It’s not the best we’ll see, but it’s a step up.
The real standout, the one you want to mark on the calendar, is Monday morning (September 14th) at Itajuba Reef. That’s where it all comes together. We’re looking at a solid 7 ft swell from the SE with a period of 11 seconds – that’s proper groundswell with some punch. The combined energy is a hefty 1288 (strong). With a light breeze and clean, cross-offshore wind, that reef is going to be firing. This one is for the experienced crew, though – 7 ft is big, and with that period, it’ll be powerful. The water temp is sitting at 68°, which is a touch warmer than normal for this time of year, so you might not need the thickest wetsuit.
Before that, there’s a few decent windows. Wednesday morning (September 9th) has 4 ft from the E with light cross-off wind and clean conditions (combined energy 233). Thursday morning (September 10th) is glassy with no wind at all, and 3 ft from the E – that’s clean, but the swell is a bit small. Saturday morning (September 12th) sees a clean 3 ft with offshore wind, but it’s only surfable, not epic.
After that big Monday on the 14th, Tuesday morning (September 15th) still has some clean 5 ft swell from the ESE, but the energy drops to 473. It’s worth a look if you missed the Monday peak. By mid-week the second week, the wind picks up and the quality fades, with onshores and cross-shore chop taking over from Wednesday the 16th onward.
To be honest, the Monday (September 14th) is the clear winner. It’s the biggest, cleanest, and most powerful swell in the whole window. If you can only surf one day, make it that one.

Information about the Itajuba Reef Surf forecast
The above surf forecast table for Itajuba Reef provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Itajuba Reef can be found by selecting the local surf guide option on the grey menu. Our Itajuba Reef 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 (Itajuba Reef) 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 Itajuba Reef 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.
