The Lowdown
Alright, let’s break this down in feet and miles per hour for the crew who think that way.
The standout is Malibu, and the window is tight. Monday morning, August 24th is the session. We’ve got a clean 3ft groundswell from the SSE with a very long 18-second period. That’s got some serious punch to it (1390 combined energy). But the real beauty is the wind—dead calm, glassy, just a light SSW breeze at 3 mph. That means silky smooth waves. The water is about 82°F, which is a degree warmer than average, so it’s feeling like a warm bath. Keep in mind, this break is inconsistent, so don’t expect set after set, but the quality will be there. It’s an intermediate wave, and these conditions are as good as it gets.
The rest of the forecast is rough. Later Monday afternoon the wind jumps to 12 mph and goes cross-shore, turning the 7ft swell into a lumpy mess. Tuesday is a total loss with strong cross-shore winds. There’s a quick moment on Thursday morning, August 27th, with a light cross-offshore wind and clean surface, but the swell is a weak, short-period 4ft from the SW at only 6 seconds. The energy is tiny (346). You could try it, but it’s not going to be memorable.
Then we hit a long, ugly patch. From Friday the 28th through the end of August and into early September, it’s mostly onshore or cross-shore wind, with waves dropping below 2ft. Most days are poor. The 31st of August morning is glassy again, but with only 2ft on offer, it’s barely a ripple.
Into the first week of September, there’s a spike around September 5th with 6ft from the E, but the wind is onshore from the east at 9-12 mph, creating messy, choppy conditions. The period is a short 10 seconds, so it’s not breaking well. The 8th of September shows a bigger 7ft swell, but with 18 mph cross-shore winds, it’s going to be a washing machine. That day is more for the kite surfers than anyone on a paddle board.
Bottom line: Monday morning, August 24th at Malibu is your only real highlight in this whole 16-day stretch. After that, it’s a long, grim run of poor conditions.

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