The Lowdown
Alright, let’s talk about Costa Banderas.
It’s a reef break, gets a fair bit of swell, and likes it from the WNW. The water is warm, about 89°F, and that’s over 4°F warmer than usual, so you’ll be comfortable.
The first few days, from Saturday 22nd through the end of the week, are nothing special. Swell is tiny, mostly 1ft to 2ft, and the winds are mostly cross-on or just okay. Energy is low, so it’s pretty weak. You might get a clean session on Sunday 23rd or Monday 24th morning with light offshore breezes, but the waves are small.
Friday 28th afternoon shows a little life, with swell around 2ft from the SW, a 17-second period, and energy jumping up. Winds are light and clean from the WNW. Saturday 29th also looks decent, with 3ft to 3ft swell, clean conditions, and solid energy. That’s the first real window.
There’s a bit of a lull from Sunday 30th afternoon through Tuesday 1st September, with messy winds and choppy surf. Monday 31st afternoon has 4ft swell but it’s cross-on and ugly.
The standout is Friday 4th September morning. That’s more than a week away, so don’t lock it in yet, but it looks good. We’re talking 4ft SW swell with a 17-second period, glassy conditions, and energy through the roof. That’s a proper groundswell for the reef. Saturday 5th morning is also promising, with 3ft SSW swell and clean winds.
First week is small and average, but the end of it into the second week has some real potential. That Friday 4th morning is the one to keep your eye on.

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.
