The Lowdown
Alright folks, let's talk about the lineup for the next couple of weeks.
The start of this run is a bit of a dead loss. We're looking at a couple of days of tiny, weak surf with onshore breezes, just not worth paddling out for. The energy is real low, like 20 and 48, so don't even bother.
Thursday the 20th is when the ocean wakes up a little. We're looking at waves around 4 to 5 feet from the northwest, with a 10-second period. The energy picks up to a moderate level. But the wind is still a bit annoying, light cross-onshore, so it's going to be a bit lumpy.
Friday the 21st is bigger, pushing 6 feet from the NW, with the energy getting up there. The problem is the wind builds onshore, making it choppy and messy. It'll be a handful, but there will be waves.
Saturday the 22nd is where we get a little bit of luck. The wind swings offshore, cleaning things right up. We've got waves in the waist-to-shoulder high range, 4 to 5 feet. It's not massive, but it'll be fun and make for some proper turns.
Sunday the 23rd is smaller, dropping back to around 4 feet. The period is short, so it's not going to have much power. It's clean though, which is nice.
Monday the 24th is a big step down. The surf is under 3 feet and the energy is weak. There's a chance of some storms, but the surf is just not happening.
Tuesday the 25th is dead flat. Nothing going on, so take the day off.
Wednesday the 26th is a messy one. Morning is just knee-high, and the afternoon gets blown out by a fresh onshore wind with a pile of windswell that has no shape. That’s just for the kitesurfers to enjoy.
Thursday the 27th sees the swell start to fill back in. The afternoon is the most interesting, with head-high waves from the NW and a long, 11-second period. There's some energy there. It might be a bit crossed up, but the long period could make it work.
Friday the 28th is a nice day. Glassy conditions and clean 4-foot waves from the NW. It's a proper surf day.
Now for the standout, and remember this is a long way out so treat it as a promising lead, not a sure thing. Saturday, August 29th. The forecast is for clean, glassy conditions, with a solid 5-foot swell from the northwest. The energy is moderate, the wind is what you want, and it looks like it could be the best day of the whole forecast. This is the one to circle on the calendar.
As we get into the next week, conditions stay active. Sunday the 30th has clean offshore winds and 4-foot waves. But the bigger story is Monday afternoon, the 31st. We're looking at 7-foot waves from the WNW on a shorter 8-second period. The energy is strong. This is a bigger, more powerful day that could offer some great waves if you're up for it.
After that, things settle down again into the first of September. The surf drops back to the chest-high range and the winds turn more onshore. The quality fades a bit.
Your best bet is Saturday the 29th. It looks like the cleanest, most fun swell of the window. The 31st could be a good session too for the more experienced crew.

Information about the Playa Santa Maria del Mar Surf forecast
The above surf forecast table for Playa Santa Maria del Mar provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Playa Santa Maria del Mar can be found by selecting the local surf guide option on the grey menu.

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 Playa Santa Maria del Mar 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.
