The Lowdown
Alright, Rusty here again. Let’s break down the same stretch of coast for the next couple of weeks at Costa Banderas. The water is a warm 89°, which is much warmer than usual for this time of year.
First thing: don’t hold your breath for the first week. It’s a long, slow grind of small, weak surf.
From Tuesday, August 4th through to Thursday, August 13th, the swell is tiny. The combined wave energy is mostly in the two-digit range, between 65 and 257. You’re looking at waves around 1ft to 2ft. The wind is often clean or glassy in the mornings, which is the best you’ll get. The swell direction is mostly SW or SSW, with a long period – up to 18 seconds sometimes – so the waves will have good shape for their size, but with these heights, it’s a real struggle for a knee-high roller. The glassy morning on Tuesday the 4th and the clean cross-off wind on Wednesday morning the 5th are the best of a bad lot, but it’s still barely a ripple.
The surf finally wakes up on Friday, August 14th and Saturday, August 15th. That’s the standout window. On the morning of Friday the 14th, it’s clean with a light NE cross-off wind. The swell is 2ft, with a period of 18 seconds from the SW. The wave energy jumps to 360, which is a real push. That afternoon, the swell hits 3ft, with a period of 18 seconds and energy up to 474. Winds are cross-off from the WNW at 9 mph, keeping it clean. Saturday the 15th morning holds that momentum with a 3ft SW swell, 16-second period, and a light ENE cross-off wind at 3 mph – glassy and clean, with energy at 372. This is the best weekend of the whole forecast. The waves are still small for many, but the quality and consistency are a big step up. It’s a reef, so it should hold that swell well.
After that, it drops back off from Sunday, August 16th onward. The swell fades to 2ft to 2ft, and the energy slides back into the 100s and low 200s. The wind stays clean in the mornings, but the punch is gone.
So, to be honest, it’s a quiet outlook. The only real highlight is that Friday the 14th and Saturday the 15th. The rest of the time, you’ll be scratching for anything rideable. The reef is consistent, but it needs the swell to work. Keep an eye on that long-range window – if it holds, that’s your best shot.
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.
