The Lowdown
Alright, let’s talk Ajo. Water’s sitting at 71°F, which is a notch warmer than normal for the season—not a big deal, but comfy.
We’re starting slow. Wednesday’s rough—rain, cross-onshore winds, and 5ft of messy surf. Forget it. Thursday morning though, that’s where it turns. Clean 5ft, cross-offshore breeze, and the energy is building (558). That’s a solid start.
Friday morning stays clean at 4ft, but small. But Friday afternoon—that’s the one. Swell jumps to 8ft from the NNW with a 14-second period, and the energy is cranked (1973). Wind’s a bit cross-onshore, but this is serious swell. Might be too much for some, but the experienced crew will be keen.
Saturday morning holds at 7ft, 13-second period, and the wind is more favorable. Still big, but cleaner. If you’re confident, that’s your weekend pick. Sunday drops to 5ft, but the afternoon gets onshore and choppy. Mornings are better, but still a bit lumpy.
Then it fades. Monday and Tuesday are marginal—4ft to 5ft, cross-shore winds, not much push. Energy drops (393 to 683). Surfable, but nothing special.
The real gem is Wednesday, September 29th, in the morning. Glassy, dead calm, and 5ft of clean NW groundswell at 12 seconds (689). That’s the cleanest surf in this whole forecast. If you can only surf one day, that’s the one.
After that, it’s small and weak. Thursday the 1st has waves but it’s choppy and onshore. Not great.
So, bottom line: Thursday and Friday mornings are your clean, smaller windows; Saturday is the bigger but messier option; and that glassy Wednesday morning is the standout.
Also, keep an eye on those longer period swells (15-16 seconds) later on—they’re better for points and reefs than this exposed beach, so don’t just chase the size.
Pick your days, and enjoy the clean ones.

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.
