The Lowdown
G’day, Rusty here. Let’s be straight – the next couple of weeks around Costa Banderas are looking small, but there’s a bit of life hiding in the second week if you’re patient.
Right now, we’re coming off a flat patch. The first real chance of a wave shows up on Thursday the 4th of August. It’s tiny – 1 ft of southwest swell with a long 12-second period, but the combined energy is weak at 65. Not gonna get anyone out of bed. Still, early morning is glassy and the water is a balmy 89°, which is much warmer than normal for this time of year – feels like a bath.
Through the rest of the first week and into the second, it’s pretty ordinary. Swell stays between 1 ft and 2 ft, mostly from the SSW/SW, with periods that bounce around but nothing that’ll light up the reef. You get clean windows here and there – like Friday the 7th morning with light ENE airs and a little 1 ft, 18-second SSW groundswell (combined energy 197) – but it’s lacking any real push. Most afternoons get a cross-off breeze from the NW or WNW, which keeps the surface tidy, but the waves are just too small to get excited about.
There’s a real gap in quality here, but then we hit a standout window starting Friday the 14th of August. Friday morning brings 2 ft of SW swell at a very long 18 seconds, combined energy at 365 – moderate but building. Winds are light off the NE, cross-off, and the water is clean. Friday afternoon is the pick, with 3 ft SW at 17 seconds, energy jumping to 474, and a solid cross-off from the WNW. That’s the best on offer – small but clean, with shape from the long-period SW groundswell suiting this reef break beautifully. It’s worth a paddle if you’re keen for some fun, lined-up waves. Crowds can be an issue here sometimes, so get in early.
Saturday the 15th maintains it: 3 ft SW, 16 seconds in the morning with glassy NE airs and a combined energy of 367. By afternoon it’s still clean but the tide might be messing with it a bit. After that, the swell fades again through Sunday and Monday back to 2 ft-2 ft, with only average conditions.
For beginners, anything over 5 ft is a push – we don’t get there, so it’s all doable for a learner if you’re happy with knee-high foam. Experts will be bored unless you’re after a longboard glide on those long-period SW lines.
So, overall: the first week and a half are mostly forgettable – lots of ordinary surf and no real push. The standout is Friday the 14th and Saturday the 15th of August, with clean, cross-off winds and building 3 ft to 3 ft SW groundswell at very long periods. That’s your window. It won’t be pumping, but it’ll be fun.
Rusty.

Information about the Costa Banderas Surf forecast
The above surf forecast table for Costa Banderas provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Costa Banderas can be found by selecting the local surf guide option on the grey menu. Our Costa Banderas 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 (Costa Banderas) 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 Costa Banderas 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.
Costa Banderas is 27 km (17 miles) from Puerto Vallarta. If you plan a holiday in Nayarit, look for hotels and other accommodation in Puerto Vallarta. Puerto Vallarta has rooms for a wide range of budgets as well as car hire and transport links.
