The Lowdown
Alright folks, Rusty here with a look at what's coming down the pipe for the next couple of weeks in our neck of the woods.
We've got a bit of a slow start on our hands, with the first few days looking pretty lackluster. The surf really starts to find its rhythm from Monday the 20th onwards. Overall, we're looking at a run of clean, manageable swell with some real standout windows of quality, especially when the wind plays ball.
The water is much warmer than normal for this time of year, clocking in at 88°F, so you can leave the steamer at home when you head out to Costa Banderas.
For the first couple of days, Friday the 17th and Saturday the 18th are pretty poor. Tiny swell around 1ft with light cross-shore winds aren’t doing us any favours. The wave energy is weak (140 to 238). Saturday afternoon does go glassy, but the swell is too small to get excited about.
Sunday the 19th sees a bump in energy (393 to 336) but with the mix of risk of thunder and light cross-shore wind, it's still ordinary. The swell is up to 3ft by the afternoon but the period drops to 10 seconds.
Now, Monday the 20th is where we start to see some life. The morning goes glassy with a clean 3ft swell and a solid 16-second period from the SW. That’s a proper groundswell with moderate energy (406). The offshore wind from the ENE keeps it clean, making this a good option to start the week.
Tuesday the 21st and Wednesday the 22nd keep that clean theme alive with morning cross-off winds. Swell hovers around 2ft to 3ft. The combined energy stays in the moderate range (280 to 343). Wednesday morning’s 3ft swell at 12 seconds is a nice little pick.
The standout of the whole period, though, has to be the morning of Friday the 24th. We’ve got a tiny-looking 2ft swell but don't let that fool you. The period is an incredibly long 24 seconds, which is a very long period groundswell. This pumps the combined energy right up to 535 (moderate), and with a light ENE cross-off breeze, it’s going to be clean. A spot like Costa Banderas will handle that long period beautifully.
We see another peak around the 27th of July into the 29th. Monday the 27th morning goes glassy with a 3ft SW swell, and by the afternoon the energy jumps to a strong 710 with clean offshore winds. That’s going to be some of the best quality we see. The swell builds to 4ft to 4ft by Wednesday the 29th morning with strong energy (649 to 738), still clean.
Thursday the 30th and Friday the 31st stay surfable but the wind starts to get a bit more onshore in the afternoons. Still, the mornings are the go with glassy conditions and clean 2ft to 3ft swells.
Into the first of August, things start to fade a bit with shorter period swell and onshore afternoon winds creeping back in. It’s still worth a look in the mornings if you’re keen for a paddle.
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.
