The Lowdown
Alright, Rusty here, let’s look at what’s coming up for Armacao.
To be straight with you, the next week and a half is mostly a write-off. We’ve got a long stretch of poor surf and cross-onshore breezes keeping things choppy and messy. Tuesday the 14th and Wednesday the 15th are tiny, basically nothing. Thursday the 16th through to the following Wednesday the 23rd is a real flat spell, with hardly any swell to speak of and a lot of wind. It’s a frustrating run.
The first real glimpse of something better shows up on Sunday the 19th. The morning stays glassy after some light rain, but the swell is only 3 feet from the NNW and the energy is weak (37). It’s the afternoon that gets interesting – the wind stays glassy, and the swell jumps to 6 feet from the NE with a period of 8 seconds. The combined energy is moderate (428). That’s a solid, clean wave for intermediate surfers. The NE direction is right on the money for this spot. The water temp is about average for the time of year, nothing to worry about.
Then we get another gap. Monday the 20th through to Thursday the 23rd is flat again. Friday the 24th and Saturday the 25th try to bring a little swell back, but the wind is all cross-onshore, and the waves are small and messy. Not worth your time.
The best bet in the whole outlook is Sunday morning the 29th of July. That’s a long way out, but it’s the standout. We’ve got a 4-foot NE swell with a 7-second period, and the wind is offshore from the WSW. The combined energy is moderate (156). The wind will be clean, giving you surfable, lined-up waves. For Armacao, that’s about as good as it gets in this forecast. Crowds are sometimes an issue, so if you can get out early, you’ll have a better chance at a quiet session.
So, to sum it up: the next week is a dud, but hold out for Sunday the 29th. That’s your day.
Rusty.

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