The Lowdown
Alright, surfers, Rusty here. Let's talk about the stretch ahead for Ixtapa Island. The water's running a touch warmer than normal for this time of year, sitting at about 88°, so you can leave the thick wetsuit at home.
This is a reef break that's a bit inconsistent, but when it lines up, it's a beauty. The best windows are all about the mornings when the wind goes glassy or light offshore. The first standout is this Tuesday morning, August 18th. We've got a clean 4ft SSW groundswell with a good 14-second period, and the wind is glassy from the NNW. The wave energy is moderate (615), and conditions are set to be super clean. This is your best bet for the early part of the forecast.
We'll see a pattern of clean mornings and choppy afternoons through the week. Wednesday morning, the 19th, is another good one with 3ft SSW swell and glassy conditions. By Friday the 21st, the swell dips a bit, but Saturday the 22nd morning brings a pulse of 4ft from the SSE, period a bit shorter at 10 seconds, but with glassy NNE winds. The energy is moderate (634).
The next real standout comes on Sunday the 23rd morning. Another glassy morning with 3ft SSW swell, but the energy is building (855). Then, on Monday the 24th, we get a fun little clean morning with a 2ft SW groundswell, but the period is a very long 17 seconds, coming from a cross-offshore E wind. That long period will be great for this reef, offering some nice shaped waves.
Looking further out, the 28th of August (Friday) morning looks promising. A 4ft SW swell with a 16-second period, glassy ESE winds, and a strong energy reading of 880. That's a solid shout. The 30th of August (Sunday) afternoon is a real wildcard. The wind goes completely calm, glassy, with a 5ft SSW swell. The energy is up there (957), but that size is pushing into the "too big for beginners" territory. For the experienced guys, that could be a magical session.
The swell builds a bit more on the 29th and 30th, with 5ft to 5ft SSW swell, but the winds are a bit messy. The 31st of August (Monday) morning cleans up again with 4ft and a light cross-offshore breeze. The energy is still strong (955). It's a good run of surf, but you have to be on it for the morning windows. The afternoons are mostly a write-off with onshore winds.
Keep an eye on the 2nd of September (Wednesday) morning too. It's a clean 3ft SW swell with a very long 16-second period and glassy north winds. That's a classic Ixtapa Island morning.
In short, the next two weeks offer plenty of chances, but the key is to be out there early. The mornings are where the magic happens. The standout days are this Tuesday and the 28th/30th, but there's something to ride almost every morning if you're keen.
Rusty, signing off.

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.
Ixtapa Island is 9 km (6 miles) from Zihuatanejo. If you plan a holiday in Guerrero, look for hotels and other accommodation in Zihuatanejo. Zihuatanejo has rooms for a wide range of budgets as well as car hire and transport links.
