The Lowdown
Righto, let’s have a look at what’s in store for Costa Banderas over the next couple of weeks.
Gotta be honest, the start is a bit quiet. Monday afternoon (31st August) is a write-off with some messy cross-shore wind and poor conditions. Not worth paddling out for.
But things get a whole lot better come Tuesday morning (1st September). We’ve got a glassy start with a light ENE breeze, clean as a whistle, and the water is sitting at 89°, which is much warmer than normal for this time of year. The swell is only around 2 ft out of the SW, but it’s a nice long period 13-second groundswell. The combined energy is moderate (159). It’s not big, but it’s surfable with good shape and no crowd pressure because it’s only _sometimes_ busy.
The real standout though, and the best on offer across the whole window, is Wednesday morning (2nd September). We’ve got a 3 ft SSW swell with a 13-second period and light cross-offshore wind from the ENE – clean, lined-up waves with moderate energy (423). This is the pick of the bunch. Not too big for most, and the reef at Costa Banderas handles that SSW direction nicely. Expect good conditions.
Thursday morning (3rd September) is also worth a mention: glassy winds, 3 ft SW swell at 10 seconds (moderate energy, 461), and clean conditions. Another good morning session.
Friday morning (4th September) has the best wave energy of the period at 761, with a 3 ft SW swell and 16-second period. That’s a very long period groundswell. Glassy conditions from the ENE again. This one is for the more experienced, as that long period can make waves a bit more powerful and shifty on a reef setup. It’ll be clean though.
After that, things drop off a bit. Saturday and Sunday (5th-6th September) still offer clean waves in the 2 ft to 3 ft range, but the energy fades. From Monday afternoon (7th September) onward, it gets pretty ordinary. There are a few mornings with glassy or clean conditions – like Wednesday 9th and Thursday 10th September – but the swell is small (1 ft to 3 ft) and inconsistent. The end of the second week (from 12th September) is basically flat or blown out, with only tiny 1 ft to 2 ft swells and onshore winds. Not worth the effort.
So, the short story: Wednesday morning (2nd September) and Friday morning (4th September) are your best bets for clean, rideable surf. The rest of the window is mostly small and forgettable, with a lot of light wind and small swell.

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.
