The Lowdown
Alright folks, Rusty here. Let’s get into it for Ixtapa Island. We’ve got a solid run of surf on the way, with a couple of real standout sessions if you time it right. The water is sitting at 89°, which is a touch warmer than normal for this time of year, so you can get away with just boardshorts.
The pattern kicks off right from Saturday morning. The 15th of August starts with a clean 5ft SW groundswell, a period of 16 seconds, and glassy conditions with a light northerly breeze. This is a proper reef break set-up, and that long period will push through with plenty of energy (1201). It’s a bit overhead, so it’s one for the experienced crew, and crowds are sometimes a factor here. This is a top pick for the first weekend.
Sunday the 16th morning is also going to be a beauty. The swell drops just a touch to 4ft SW, but it’s dead calm with glassy conditions and a few storm clouds around. Clean, smooth lines with moderate energy (746). Ideal if the Saturday crowd put you off.
Midweek gets smaller and lighter, but the mornings hold clean waves. Monday and Tuesday mornings offer 4ft SW/SSW swell with light cross-offshore winds and clean faces. Consistency is an issue here—this break is known to be inconsistent—so you gotta make the most of the windows when the sets roll through.
Now, for the real heavyweight of the forecast. Look towards the 21st and 22nd of August. Friday morning the 21st has a 6ft SE swell with clean cross-offshore wind and solid energy (978). It’s a step up in size. Then Saturday the 22nd sees a big pulse of 13ft S swell with a 12-second period and massive energy (4497). This is massive. It's only for experts—beginners stay well clear. The wind is cross-shore and moderate, so it’ll have some chop on it, but for the experienced crew, this is serious power.
The end of the run brings another highlight. Friday morning the 28th of August has a 5ft SW groundswell with a very long 17-second period, clean cross-offshore wind, and huge energy (2027). Long period swells can run a bit straight on the beach, but on this reef, it’ll line up beautifully. Then Saturday the 29th of August morning serves up 5ft SSW swell, glassy conditions, and 16-second periods (1582). That’s a top-notch session for any surfer who knows what they’re doing.
To sum it up, the standout windows are the mornings of the 15th and 29th of August for clean, head-high glass, and the 22nd of August for the big-wave crew. The second week looks promising but keep an eye on the weather as we get closer.
Rusty.

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

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 Ixtapa Island 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.
