The Lowdown
Alright, Rusty here again, same spot, different numbers. Ixtapa Island, a reef break that’s a bit temperamental – doesn’t pump every day, but when it’s on, it’s on.
Water’s a warm 88° – that’s a touch toastier than normal for this time of year.
Don’t even think about paddling out on Sunday the 16th this afternoon – cross-on wind, choppy mess. Save your energy.
Monday morning the 17th is a different story. Wind’s light from the NNW, cleaning up that 4ft SW swell. The wave period is a long 14 seconds, real groundswell energy (667 energy). It’s the kind of morning when a reef like this shows its soul.
The absolute pick of the whole run is Tuesday morning the 18th. Glassy as a mirror, 4ft SSW swell at 14 seconds, 615 energy. That is a dream session – clean, fun, just you and the ocean.
Wednesday morning the 19th is also glassy with 4ft SW swell, a touch less energy (554) but still lovely.
Things shrink down through the rest of the week. Thursday morning the 20th is clean at 3ft, and Friday morning the 21st is glassy but tiny at 3ft from the S with a short 10-second period – not much push.
Next true standout: Sunday morning the 23rd. Glass again, 2ft from the SW but with a very long 18-second period, pumping out 836 energy. Small but perfect for the reef.
Monday the 24th morning offers offshore breeze and similar long-period groundswell – another clean little session.
Second week gets quiet, then kicks back to life. Friday morning the 28th is a big one: glassy, 4ft SW swell, 16 seconds, 880 energy. That’s the best-looking swell on the whole forecast. Saturday morning the 29th has even more juice – 5ft from the SW, 16 seconds, 1105 energy – but cross-shore wind might mess the surface. That’s a serious amount of water for experts.
Sunday morning the 30th is glass again with 4ft SSW swell, 15 seconds, 770 energy, and Monday the 31st finishes with glass and 4ft SSW, 14 seconds, 667 energy.
This reef is inconsistent, so you gotta be patient. Crowds can be a thing, especially on those glassy mornings – get there early. The best days are Tuesday 18th, Sunday 23rd, Friday 28th, and Sunday 30th.
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. If you surf the same spot (Ixtapa Island) 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 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.
