The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the table.
To be straight with you, the next week or so is looking pretty quiet. There’s a real dry spell from now until around the 24th of September where the surf is just too weak and messy to get excited about. We’ve got small, short-period windswell and cross-shore winds messing things up. You’re looking at a solid 11-day gap with nothing worth paddling out for.
The first real glimmer of hope shows up on the 24th of September, and things build from there. The standout window is the 25th of September. That’s where we get a proper pulse of longer-period groundswell from the NNE, with wave heights around 5 ft and a period of 14 seconds. That’s serious energy coming through – combined swell energy is up at 807 (strong wave energy). That kind of period means well-shaped, powerful lines, but it’ll be breaking a bit straight on the beach, so the reef at Aviones will handle it much better. The wind will be cross-off from the East at 15 mph, which cleans the faces up nicely. Water temp is sitting at 85°F, about 1°F above normal for this time of year, so it’s just a touch warmer than average – nothing crazy, but pleasant.
Aviones (reef break) is the spot to be. It’s exposed to the north and this swell is coming from just the right direction. It’s very consistent here, so you won’t be waiting around forever between sets. The crowd factor is something to keep in mind though – it’s often got a few heads out, so expect company. The difficulty is beginner-friendly at this size, but anything over 5 ft starts pushing it for less experienced surfers. Thursday the 24th kicks things off with a 4 ft swell, but the wind is cross-shore and it’s marginal. Friday the 25th is the real highlight – that’s the day. The period is over 15 seconds, which is very long, and combined with the clean offshore wind, you’re looking at smooth, powerful reef waves. Saturday the 26th still has some leftover energy, around 4 ft and 12-second period, but the wind backs off and it’s less punchy. After that, it slowly fades back down through the end of the month.
So bottom line: if you’ve got patience, the end of September is worth waiting for. Friday the 25th is your best bet – solid groundswell, clean conditions, and Aviones doing what it does best. Don’t bother before the 24th.
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.
