The Lowdown
Alright, Rusty here again. Let’s break it down in feet and Fahrenheit.
The big picture is a consistent, long-period SW groundswell, but it’s mostly small. The best window is right at the start. The first couple of days are the pick, then there’s a dry spell until things perk up again around Monday, September 21st. There’s a real gap of poor conditions from Friday the 11th through Monday the 14th – not worth your time.
The absolute standout is Thursday, September 10th at Costa Banderas (Costa-Banderas). We’ve got a clean 3ft SW swell with a 16-second period – that’s proper groundswell, with moderate energy (365 in the morning, 328 in the afternoon). The wind is light and cross-off, so you’re looking at clean, lined-up waves. The water temp is about normal for this time of year, nothing strange. This is a consistent reef break, but it can get a crowd sometimes, so plan accordingly. The swell direction is a perfect match for the optimum WNW direction. That Thursday morning and afternoon are your best bets.
After that, it drops off. Friday the 11th and Saturday the 12th see the swell shrink and cross-shore winds mess things up. Sunday the 13th is a total loss.
We get a bit of a rebound on Tuesday, September 15th in the afternoon. The swell comes back to 2ft from the SW, period still solid at 16 seconds, with moderate energy (283) and clean cross-off winds. Not as good as Thursday, but definitely surfable and clean.
Wednesday the 16th has a clean morning, but the afternoon goes offshore – great for shape, though the swell is a little smaller.
Things start looking promising again toward Monday, September 21st. The swell builds back to 3ft, period around 17 seconds, and the morning looks glassy with light cross-off winds and solid energy (361). That’s a promising long-range call, but don’t book your flights yet – forecasts can change.
From the 22nd onward, it’s more small, clean, and ordinary. You can get wet, but it’s nothing special.
Bottom line: Thursday the 10th is your day. Tuesday the 15th is a decent backup. Keep an eye on Monday the 21st.
Rusty, out.

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.
