The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the table for the next couple of weeks.
We've got a slow start. The forecast shows mostly poor conditions, with a lot of small, weak, and choppy slop. For the first week or so, you're really not missing much. The biggest issue is the wind – it's mostly a moderate cross-shore or cross-off breeze that's keeping things messy, and the swell is tiny, mostly under 3 ft. The energy is weak, reading in the 50s and 60s for that time, so it feels pretty lifeless.
The standout window doesn't really show itself until late, and it comes with a big caveat. Around Tuesday the 25th of August, we are looking at a real jump in size. The swell at Aviones pushes up to 8 ft from the ENE, but the wind is a cross-onshore 15 mph, making it choppy. On Wednesday the 26th of August, the swell drops slightly to a still significant 6 ft from the E, and the wind eases to a light 6 mph cross-onshore. The energy on that morning is pumping hard at 973, but the surf is still only in the "marginal" bracket. With that onshore wind and a beach/reef setup, this is actually looking more interesting for the kiteboarders than for a standard paddle session. For the experts only, you might get a few, but it will be a battle.
You'll then see a sharp drop-off again, with waves falling back under 3 ft and the cross-shore winds returning, keeping things ordinary right through to the end of the forecast on September 2nd. There's a brief moment on the 31st of August with light winds and clean-ish conditions, but the swell is barely 2 ft. Honestly, the only real potential through this whole outlook is that big push on the 25th and 26th, and even that's a compromise.
So in short: a long run of flat to poor surf, one big but choppy swell event for the experts only around the 25th and 26th, and then back to flat. It's tough, but these things turn around. Keep the wax on the board and wait for the next one.
Rusty.

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