The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on offer for Costa Banderas over the next couple of weeks. We’ve got a bit of a slow-burn outlook; nothing too exciting, but there are definitely a few sessions to get excited about.
Right off the bat, the standout window kicks off Sunday afternoon, September 6th, with a light cross breeze and a modest 3ft swell rolling in from the SSW. The water is sitting at 89°, which is a whopping 4° warmer than usual for this time of year. It’s like bathwater out there. The combined swell energy is moderate at 507, but the wave comment is a bit flat with marginal conditions, so it’s not a full standout.
The real gem for this first week lands on Monday morning, September 7th. Costa Banderas (Costa-Banderas) sees a clean 2ft SSW groundswell with a period of 14 seconds, light NE winds making for cross-offshore conditions, and that sweet, clean surface. The energy is moderate at 396, and the waves are expected to be good. The same afternoon builds a little more to 3ft from the W with a moderate 10-second period, still clean with NW cross-off breezes (318 energy). This is your pick for the week; the waves are clean, consistent, and ideal for an intermediate on a reef break.
Tuesday morning, September 8th, offers a smaller 3ft W swell (242 energy) that’s clean but very ordinary. The afternoon picks up again with the same size and another clean session (267 energy). We see smaller pulses through Wednesday and Thursday, with Wednesday afternoon offering a 2ft SSW swell with a very long 17-second period (302 energy), making for glassy, well-shaped waves but with longer lulls between sets. That longer period will favor the reef setup here.
As we move into the second week, the surf settles into a smaller, cleaner groove. Nothing jumps out as huge, but the consistency sticks around. On Monday, September 14th, the swell drops to 1ft from the SW but with a very long 18-second period (159-171 energy), which is a proper groundswell, but it’s small and a bit cross, so it’s a pass.
The best of the second week comes on Saturday morning, September 20th. We’ve got a clean, glassy 2ft SW groundswell with a 19-second period. The energy is strong at 333, and with glassy conditions and ENE winds at just 3 mph, this will be a dream session for anyone who can handle the long period and the reef. It’s clean, it’s warm, and it’s set to be a beauty. Keep an eye on that one as we get closer.
Other than those few highlights, it’s a lot of small days with clean but unexciting swell. There’s a stretch from Tuesday, September 15th morning, through Thursday, September 17th afternoon, where the surf is either poor or very ordinary, with only a couple of decent morning windows. The period from Friday, September 18th morning through Monday, September 21st offers a few more promising but not spectacular pulses. It’s not a classic run, but for this area, it’s a perfectly normal pattern. You’re not going to miss much if you wait for the glassy days.
This is Rusty, signing off.

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.
