The Lowdown
Alright, Rusty here. Let's chew the fat on what Ajo's got cooking for us.
Right off the bat, the first week is a slow burner, no two ways about it. We're looking at a flat spell to kick things off, so don't rush to wax up. The real story starts building from the middle of next week.
The first real glimmer of hope hits on Thursday, September 17th, in the morning. We've got a clean 5ft swell from the NW, and the wind is dead glassy. That's a beautiful thing. It's going to be clean, but that wave energy is moderate (547) and it's a decent period groundswell at 11 seconds, so you'll get some proper lines. It's not massive, but after the dry spell, this is the standout. Expect some company though, as Ajo can get crowded.
Then, the next morning on Friday, September 18th, is even better if you can believe it. The wind is absolutely dead calm, glassy as a mirror. The swell drops a touch to 4ft, but you've got a long-period 12-second NW groundswell packing a solid punch of energy (559). This is your best bet for the cleanest, most lined-up waves of the whole outlook. Absolute magic for a surfer who knows their way around a point or reef.
Looking further out, Wednesday, September 23rd, morning is another glass-off moment with a 4ft NW swell. It's a good option, consistent, but it's not quite the punch of that Friday session.
Now, for the big dog. On Friday, September 25th, in the morning, the forecast is showing a huge 8ft NW swell with a 14-second period. The combined energy is massive (2519). The wind is light and cross, but the report is straight-up saying it's going to be too big for this break. That's expert-only territory, if it's even makeable. For the average punter, that's a day to watch from the shore.
So, to sum it up: the first few days are a write-off. The standouts are the Thursday 17th and especially the Friday 18th morning sessions with the glassy conditions and clean, long-period groundswell. The 25th is for the brave (or the foolish). Stay patient, boys.

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