The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s on offer.

Honestly, for the next 16 days, we’re staring down the barrel of a pretty bleak run at Mar Bravo. The wind is the main culprit here – it’s howling from the east and northeast, staying cross-on or onshore for the entire period. This setup is just going to keep the surf messy and lumpy, with no real window of clean conditions. The swell is small and weak, with a short period, and the water is a touch warmer than normal at 82°F.

We kick off Thursday, August 6th, with 4ft of weak, short-period ENE swell, but the 16 mph cross-on wind from the east chops it up into poor surf. Combined energy is a weak 85. It’s a no-go.

Friday, August 7th, the swell nudges up to 4ft, but the wind is still a problem. The energy picks up a little to 103 in the morning, but it’s still cross-on and choppy.

Saturday, August 8th, sees the swell reach 4ft with a combined energy of 127, but easterly winds at 19 mph make it a fresh, lumpy mess. Not worth paddling out.

Sunday, August 9th, is much the same – 4ft swell, 105 energy, and lumpy cross-on winds.

Monday, August 10th, the swell drops back to 3ft, and the energy dips to 82. The pattern of easterly winds and poor surf continues.

From Tuesday, August 11th, through to Thursday, August 13th, the swell bottoms out. We’re looking at 3ft to 3ft swells with combined energy as low as 21, all spoiled by cross-on winds. Not a single one of these days is worth talking up.

The second week doesn’t get any better. From Friday, August 14th, through to Friday, August 21st, the swell stays small, mostly between 3ft and 4ft, with the highest energy hitting 170 on the 20th. But the wind just doesn’t let up. It’s cross-on every morning, onshore every afternoon, and that’s a killer for any chance of quality surf.

There are no standout days here. The combination of persistent onshore wind and weak, short-period swell means the setup is honestly more interesting for kite surfing than paddle surfing. For the entire 16-day window, you’re better off sitting this one out.

Rusty.

Information about the Mar Bravo Surf forecast

The above surf forecast table for Mar Bravo provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Mar Bravo can be found by selecting the local surf guide option on the grey menu. Our Mar Bravo 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 (Mar Bravo) 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 Mar Bravo 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.
