The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s on the cards for Itaúna over the next couple of weeks. It’s a classic point break, exposed to the east, and it takes a bit of swell to get it humming. The water temp is sitting around 73° right now, which is pretty much average for this time of year, nothing to write home about.

The next few days are pretty grim, to be honest. Tuesday the 1st and Wednesday the 2nd are a write-off – messy, onshore winds and junky waves. You’d be better off staying on the beach. Thursday the 3rd cleans up a bit with a cross-offshore breeze, but the swell is still a bit all over the place and the quality is nothing special. We’ve got a real gap here; it’s not until Friday the 4th that things start looking interesting.

That Friday morning is the first real standout. The wind swings offshore from the NNE at just 3 mph, the swell drops to a manageable 4 ft from the SSE with a long 11-second period, and the combined energy is a solid 411 (moderate). This is a proper point break wave – that longer period groundswell will wrap in nicely and give you some nice lines. It’s an advanced spot and it can get crowded sometimes, so get in early.

Saturday the 5th has a moment early – glassy conditions with zero wind, but the swell is tiny at 2 ft. Not really worth paddling out for. Sunday the 6th and Monday the 7th are mediocre, with onshore wind and messy surf. Tuesday the 8th has some size, up to 8 ft, but the wind is a mess and it’s just poor.

Then we get another real window. Wednesday the 9th morning looks very promising. The wind is light cross-offshore from the ENE, swell is 6 ft from the SE with an 11-second period, and the combined energy is 890 (moderate). This is the kind of day you circle on the calendar. The swell direction is slightly off the optimum east, but with that period and the point break setup, it should still produce some excellent waves. It’s still an advanced wave, so if you’re not comfortable with overhead point surf, sit this one out.

The following weekend, Saturday the 12th and Sunday the 13th, has some potential but the winds are strong and cross-offshore, which can make it a bit bumpy. Sunday the 13th morning has a moment of glassy conditions with a 3 ft SSE swell, but it’s small.

Looking further ahead to the 15th of September, Tuesday morning is a real highlight. Glassy conditions with a light N wind, a 5 ft swell from the SSW at 12 seconds – that’s a long period groundswell. The combined energy is 853 (moderate). For a point break, that long period is a good thing; it’ll hold up and give you long, clean walls. This is another day that stands out as the best on offer, but being more than a week out, treat it as promising but not locked in.

Overall, the best windows are Friday morning the 4th, Wednesday morning the 9th, and Tuesday morning the 15th. Get on them.

Rusty.

Information about the Itaúna Surf forecast

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

Itauna is 5 km (3 miles) from the city of Saquarema. If you plan a holiday in Rio de Janeiro, look for hotels and other accommodation in Saquarema. Saquarema has rooms for a wide range of budgets as well as car hire and transport links.
