The Lowdown
Alright folks, Rusty here with the look ahead for Costa Banderas.
We’ve got a bit of a slow burn to start. The first real glimmer of proper surf comes in on Thursday, September 5th. The build-up before that is pretty marginal, so don't get too excited about the opening days. This reef is fairly exposed to the swell, so it needs a decent push.
The standout window is without a doubt Saturday, September 5th. We’re looking at clean, chest-high waves around 3ft pushing in from the SW, and the wind is going to be light offshore from the ENE at just 3 mph. The water is sitting at a balmy 89° which is much warmer than normal for this time of year, so a shorty might not even be needed. The combined energy of all swells is moderate (706), so there's some proper push behind it. It’s a consistent spot so it should be fun, but because it’s a reef break and consistent, expect it to get busy. The breeze is super light, so the surface will be clean, offering up some nice lined-up walls.
The weekend hangs around with similar 3ft swell on the Saturday afternoon, but the wind swings more cross-off from the NW, so the morning is definitely the call. Into Sunday and Monday the swell pulses up slightly to 4ft, but the wind gets messy with cross and cross-on conditions and the energy drops off, making for a choppier, less appealing session.
After that, the swell drops back and we get a long run of knee-to-waist high (1 to 2ft) surf for pretty much the whole second week. There are some glassy mornings, like on Monday, September 14th and Tuesday, September 15th with that super long-period SW groundswell (18 seconds) sliding through. That long period will create some fat, walled-up lines, which is sweet for a reef, but with the tiny size, it's more of a longboard cruiser session than a rippable wave. The energy is weak to moderate (162-199) so it’s low on punch.
Looking further ahead, Thursday, September 17th, is a wildcard. The morning shows a glassy 1ft swell coming from the SW with a *very* long period of 22 seconds. The energy is moderate (311) and combined with that period and glassy conditions, it’s got promise for some long, clean lines if the swell fills in. The following day, Friday, September 18th, also looks promising with clean 2ft surf and similar energy (315-377). Those are ones to keep an eye on, but they are a long way out, so don't bank on it just yet.
The bottom line: Saturday morning, September 5th is the clear winner. 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.
