The Lowdown
Hey folks, Rusty here.
It’s been a slow start, but there is a spark in the water.
I’m looking at Costa Banderas (Costa-Banderas) for this whole period. Water temps are way above normal for the season, sitting about 2° warmer than average. That’s a big deal for comfort.
Through the end of August, the swell is small but clean. We’re dealing with a long-period groundswell from the SW. Tuesday the 25th afternoon is nothing special: a weak 1 ft with a 16-second period and cross-off wind. Energy is low at (166). Wednesday is still tiny.
However, Thursday the 27th morning kicks off with a glassy surface, a tiny 2 ft wave, but energy climbs to (238). It’s the best of the small stuff.
The real turning point is Friday the 28th afternoon. The swell bumps up to a clean 3 ft from the SW, period holding at 17 seconds. Combined energy hits (449). And best of all? The wind goes glass. This is a killer window for a clean, long-period swell. Saturday the 29th morning is still good, with 3 ft waves and a clean cross-off.
From there we get a few smaller mornings.
Now, the meat of the forecast is Monday September 8th. We see a significant swell arrive. Tuesday the 8th afternoon is the standout: 6 ft of SW swell with a 13-second period and offshore wind from the north. The energy reading jumps to (1518). That’s a serious amount of water moving. This is for experienced surfers only.
Wednesday the 9th morning holds at 6 ft from the WSW, with a 12-second period, and side-offshore wind, keeping it clean but a little more tricky.
Since the swell direction fits the break’s preference fairly well, and this reef is consistent, it should hold decent shape. But that size means it’s strictly for the confident crew. Beginners, sit this one out.
So here’s the call: small fun surf for the next few days, and a heavy, expert-level swell to look forward to in the second week.
Stay stoked.
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.
