The Lowdown
Alright folks, Rusty here. Let's have a look at what’s on the menu for Ajo over the next couple of weeks.
We’ve got a bit of a slow start to be honest, with a long stretch of days where you’re better off doing something else. The water here is sitting at 71°, which is a touch warmer than normal for this time of year, so it’s not a bad day to just have a float, but the surf is straight-up poor for a good while.
The first real blip on the radar comes on Thursday the 17th for the morning session. We’re looking at some clean surf with a 5ft swell from the NW, an 11-second period, and light cross-offshore winds. The combined wave energy is 558, which is solid. It’s not huge, so it’s still fun for the average surfer, but the conditions are right.
Things get interesting for the Friday the 18th afternoon. This is a standout, but you have to be an experienced surfer. The swell jumps to 7ft from the NNW with a very long 16-second period, creating a massive combined energy of 2379. The wind goes glassy, dead calm. It's going to be clean and powerful. But honestly, for a beach break like Ajo, that long period might make it close out a bit and it’s too big for anyone but the experts. Still, if you know what you’re doing, this is the pick of the first week.
The Saturday the 19th morning carries on that big swell, still 7ft from the NNW (13-second period, 1677 energy), and we get clean conditions with a light offshore breeze. Same caveat though: it’s still a big, powerful wave, and only for the crew who can handle it.
After that, it drops off and gets messy or marginal through the next week. A quick mention for Monday the 30th morning – that’s a long way out so don’t get your hopes up just yet, but the chart is showing another clean session with a 6ft NW swell, 11-second period, and glassy conditions (703 energy). Could be a redemption day at the end of the month if it holds.
So, to sum it up: Friday afternoon the 18th and Saturday morning the 19th are the best on offer, but they are for experts only due to size. For the everyday surfer, Thursday morning the 17th is your safest bet for a clean, manageable wave.
Rusty.

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.
