The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cooking for Costa Banderas over the next couple of weeks.
First up, the overall picture is pretty mellow. We’ve got a long, drawn-out run of small, average waves. Nothing to get overly excited about, but there are a few windows where conditions clean up enough for a sneaky session. Don’t expect any pumping swell; this is more about making the most of what’s on offer.
The best bet of the whole outlook arrives on Friday, 14th August, in the morning. The swell is tiny at 2ft from the SSW, but that long period of 18 seconds will give it some shape. The real winner here is the ENE breeze at 3 mph, making for clean conditions and manageable energy levels (383 combined energy). It’s not a day for heroics, but for a cruisy longboard or funboard session, that window is the standout.
Thursday morning, 14th August, is also worth a look first thing with a glassy, clean surface and 2ft SSW swell (383 energy). The afternoons get a bit chopped up from the afternoon seabreeze, so the morning windows are the ones to target.
Look out for the morning of Saturday, 16th August. We’ll see some glassy conditions with 2ft from the SW and a period of 14 seconds. It’s small but clean.
After that, from around the 20th of August into the third week, the wave heights drop right off to 1ft and the energy fades (down to 89-150 range). It gets messy with onshore and cross-onshore winds. There’s a good stretch of poor surf from Friday, 21st August, through to the end of the forecast period. A morning glass-off on Monday, 24th August, might give you a knee-high wave, but you’ll be scratching for it.
Overall, don't plan your week around this. The waves are small, the consistency is okay but the size isn't. If you’ve got a longboard and patience, the Friday morning on the 14th is your best window. The rest of the time, it’s mostly a flat spell with a tiny bump or two.
Stay safe out there.
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.
