The Lowdown
Alright, Rusty here, lookin’ at Costa Banderas. We got a few fun windows, but nothing huge on the horizon.
The best session of the whole run is Saturday morning, August 29th. There’s a clean 3ft swell from the SSW with a super long 16-second period. Combined energy is moderate at (476), and a light 5 km/h NE breeze keeps it glassy. This spot is a reef break that’s fairly exposed, and the direction is a good match. The water is way warmer than usual at 89°F right now.
Next up, Thursday morning, September 3rd, has clean 2ft waves from the SW with a 15-second period and a light 10 km/h ENE wind. Energy sits at (490). Clean.
Friday morning, September 4th, also looks solid: 3ft from the SW (601 energy) with just a 5 km/h ENE breeze. Clean. And Saturday morning, September 5th, gives you 2-3ft from the SSW with a 10 km/h NE wind for clean surf (481 energy).
Thursday morning, September 10th, gets totally glassy with 2ft from the SW on a 15-second period. Calm winds and (347) energy, but the swell is small.
The afternoons are mostly blown out with cross-shore or onshore winds, and there’s a risk of storms on some days. After the first week of September, the swell really drops to 1-2ft with low energy, so you’ll be scratching around. The period from the 7th to the 12th is mostly poor with very little to recommend.
So, aim for Saturday the 29th of August, or Thursday and Friday mornings of the first week of September for the cleanest conditions. The 10th is a gamble for glass.
Stay salty.
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.
