The Lowdown
Alright mates, Rusty here. Let's break down the surf for this stretch. It ain't looking like a game-changer, but there are a couple of windows to keep an eye on.
For the first few days, it's pretty quiet. We've got a tiny, long period groundswell but it's weak. The first time you might want to paddle out is the morning of Saturday, August 29th. The combined energy ticks up into moderate territory (440) with 0.9m of SW swell. Wind looks light and cross-offshore, so it should be clean.
But the real standout, the one you should aim for, is the morning of Thursday, September 3rd. We get a glassy, clean 0.5m SW groundswell with a very long 18-second period, and the combined energy is a solid 347. The wind is practically dead calm, just a slight air. This will give you clean, wrapping lines at Costa Banderas (reef). The water temp is 32°, which is a lot warmer than usual for this time of year, so it'll be like a warm bath out there.
That 18-second period is a long interval groundswell. At a reef setup, that's ideal; it won't just close out. The sets will be spaced out but have some real punch. The afternoon of that same day keeps the energy high at 485 with 0.9m and clean, light wind. After that, the following days drop off into average conditions with more cross-shore breeze.
So, keep it simple: the first week is a write-off. Your best chance is the morning of Thursday, September 3rd. Get on it.
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.
