The Lowdown
Alright, let’s call it like I see it for Mar Bravo. The next 16 days, right through to the 21st of August, are a total bust for any decent surf. There’s absolutely nothing worth paddling out for.
Yeah, there’s swell in the water, but it’s all short-period, junk windswell from the ENE and NE, with periods between 5 and 7 seconds. That ain’t gonna make a wave worth riding. And the wind is the real killer – it’s hammering from the east and northeast, cross-on or onshore, at 12 to 19 mph, all day, every day. That’s gonna leave the surface all chopped up and lumpy. The water’s sitting at 82°, a touch warmer than usual, but that’s the only silver lining.
The combined energy will get up there, hitting 177 (moderate) on Saturday morning, and it stays in the triple digits for a stretch, but it doesn’t matter when the wind’s ruining it. With this constant onshore breeze and lumpy sea, this spot is looking way more fun for a kite than a paddle board.
It’s a long, dry spell. There’s no standout session, no hidden corner to go find. Sometimes you just get a blank forecast, and this is one of those times. The swell height stays between 3 ft and 4 ft, so it’s not dangerous, just frustrating. You’re better off waiting for the next weather pattern to change things up.

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.
