The Lowdown
Alright, grab your board, let’s talk about what’s coming up at Ajo.
Honestly, things are looking pretty flat and quiet for the next little while. We’ve got a good stretch of minimal swell to start with. The first few days are barely a ripple; Tuesday and Wednesday the 18th and 19th will see tiny 1ft to 1.0ft wind-affected waves with no real energy to speak of. You’re better off doing something else. There is a gap of two to three days with no real surf to recommend.
Thursday the 20th morning the swell starts to creep up a bit with 4ft from the NW, a period of 11 seconds, and moderate combined wave energy of 273. The wind is cross-shore, making the conditions a bit messy. Not a standout, but the energy is starting to build. By Friday the 21st we’re up to 5ft from the NW with a period of 10 seconds, and the combined energy bumps up a bit to 450. The wind stays cross-shore and light, keeping it rideable but still marginal.
Saturday the 22nd looks like the pick of this first period. The morning brings 4ft NW swell with a 9-second period, combined energy of 206, and a light cross-offshore breeze that will clean the waves up. By the afternoon, it turns glassy with the wind dropping off, making for cleaner faces. It’s not huge, but it’ll be surfable and fun if you don’t mind it small.
Skipping ahead, there is a notable spike on Thursday the 27th of August. We are looking at a solid 8ft NW swell coming in with a period of 10 seconds and massive combined energy of 906. This is a lot of power for Ajo. The wind is cross-shore, and at this size, it’s really only for skilled crew—beginners should sit this one out. Friday the 28th the swell drops to 5ft but with clean conditions in the morning. Saturday the 29th sees 4ft NW swell with glassy conditions in the morning—good for a quiet session.
All in all, the window is quite limited. The Saturday 22nd morning session has the best combo of clean wind and rideable swell without being too big, though the water is much warmer than normal for this time of year, around 75°, which stands out.
If you can wait, the bigger swell on the 27th is the real event for experienced surfers—just watch out for the afternoon wind picking up.
Stay keen,
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.
