The Lowdown
Alright, mate. Rusty here, and I'm looking at the same stretch of water, just in feet and miles per hour.
This is a tough run. The first 10 days or so are a washout. From now until about the 24th of August, the wind is a dirty easterly, and it's got the surface all chopped up. The swell is mostly short-period, wind-driven slop, so don't expect much.
The only spot we've got is Aviones (Spain). Water temp is 84°F, which is about average for this time of year.
The first real glimmer of hope is late on Monday, the 25th of August. The afternoon shows a glassy, dead-calm sea with a clean 8ft swell from the east, holding a moderate amount of energy (1361). That's a serious wave, but it's getting into the realm where only the experienced blokes should be out. The period is short at 8 seconds, so it's not the most ground-swell perfection, but that glassy wind will make it the most rideable thing in the whole 16-day window.
Before that, on the morning of the 25th, there's a 6ft east-northeast swell with a light cross-onshore breeze and a risk of thunderstorms. It's a bit iffy, but could be a sneaky one if the wind stays light. The combined energy is moderate (427).
After that, it's back to puny, weak waves and clean but cross-off winds. It's a dry spell, but it's normal for the area. The forecast can always flip. For the standout, it's that Tuesday afternoon on the 25th. The glassy conditions at Aviones with an 8ft east swell will be the best of a pretty average lot. Bring your big-wave board.
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.
