The Lowdown
Alright folks, it’s Rusty here, and I gotta be straight with you – this outlook is a tough one.
We’re looking at Chaweng Malibu, and to be honest, there’s just nothing going on for the paddle crew. The entire 16-day window is a flat, blown-out mess. We’re talking about a run of days with no real swell to speak of, and when there is a tiny blip of energy, the wind is just ruining it. The combined wave energy is laughably weak, with the highest reading coming in at a paltry 10 (ten) – that’s barely a ripple. You’ll be bobbing around on a mill pond more than anything else.
The water is a warm 87° – a touch warmer than normal for late July, which is nice for a swim, but it doesn’t help the surf.
We start off on Tuesday the 28th with a thunderstorm risk and a 16 mph cross-shore wind. Then Wednesday the 29th sees a bit of a 0.3 ft swell from the NW, but the period is a pathetic 4 seconds. It’s basically wind chop. The wind is onshore or cross-onshore almost every single day, from the WSW, WNW, or SW, and it’s often a fresh breeze of 16-22 mph, or even a strong breeze hitting 25-28 mph towards the end of the run. That’s kite surfing weather, not surfing weather.
The swell heights never get above 2 ft, and the periods are mostly in the 2-6 second range – pure, weak wind swell. The waves are just not there. This is one of those blank runs that’s unfortunately pretty normal for the area when the conditions won’t line up. The only highlight is a few clear mornings, like on the 5th, 6th, and 7th of August, but even then the swell is so weak and the wind is still onshore, it’s not worth paddling out for.
We’ve got a long 16 days ahead of flatness. Forecasts can change, but right now, don’t bother waxing the board. Save your energy.

A general guide to surfing at Chaweng Malibu 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 Chaweng 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.
