The Lowdown
Alright, let’s talk Avila Beach in feet and Fahrenheit. It’s Rusty, and I’ll tell you straight – the next couple weeks have some waiting time before we see any real juice.
The first session that’s worth paddling out for lands on Monday, September 14th. Morning has head high swell, about 6ft coming from the WNW with an 8-second period. Winds are light cross-offshore, keeping it clean. The combined energy is a moderate 835 – decent push. Crowds are possible, so keep an eye out. Water temp is about 65°, a touch warmer than normal for this time of year.
Tuesday the 15th through Friday the 19th is a real dry spell. Swell drops to ankle to knee high with long periods, and the winds are mostly cross or light cross-on. Not worth a second look.
Saturday the 19th afternoon brings a bump – 7ft from the WNW but only a 7-second period. That’s short-period windswell, bumpy and not great shape. Wind is clean cross-off. Combined energy is 814 – moderate. For experts only at that size.
Sunday the 20th morning is the best of the first week. You’ve got 6ft from the NW, 8-second period, clean cross-off winds. Combined energy jumps to 1098 – solid, strong. Only for experienced surfers because the size is up there.
Then a lull from the 21st to the 22nd. Messy and small.
Now, the real standout – Wednesday, September 23rd. Morning has clean waist high swell, around 3ft from the SW, and a very long period of 15 seconds. That’s proper groundswell. Combined energy is 736 – moderate. Both morning and afternoon are glassy – the afternoon goes dead calm with offshore wind from the NNE at 0 mph. The water will be like a mirror. This is the pick of the whole forecast.
After that, Thursday the 24th is blown out with onshore wind. Friday the 25th morning has another glassy window, just small at 2ft with a 14-second period – good for a longboard.
Saturday the 26th morning offers 4ft from the WNW, 10 seconds, clean cross-off winds – nice for intermediate surfers. Then Sunday the 27th afternoon sends a pulse of 7ft from the WNW, but only a 6-second period – short and dumpy, for experts only.
So, the first week is slow with a few OK windows. The second week has that gem on Wednesday the 23rd – glassy, long-period, clean. Circle that date. The rest is a waiting game.
Stay stoked,
Rusty

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