Diano Marina Surf Forecast and Surf Report

Alright, let’s break down Diano Marina for the next sixteen days. Honestly, it’s a flat spell with barely a ripple for the first two weeks. You’re looking at a whole lot of nothing or tiny, weak, choppy junk.

The wave energy is mostly pathetic – single and low double-digit numbers like 13 and 21 (weak energy). Most days have onshore or cross-shore winds messing things up. There’s one clean morning on Tuesday, August 4th, with a light cross-offshore breeze, but the wave height is only 2ft from the east-northeast with a period of 3 seconds – not rideable.

We do see a little more energy creep in during the second week. Thursday morning, August 14th, is clean with a light cross-offshore from the north, and a small 2ft southwest swell with a 5-second period, but energy is still only 19 (weak). Friday morning, August 15th, is clean again with a 2ft southwest swell and a 6-second period, energy at 53 – still weak.

The only session that’s even worth considering is Monday morning, August 17th. This is the one time the rating breaks through to a 1 out of 10 – “surfable waves but very ordinary conditions”. We’ve got a 3ft south-west swell with a 7-second period, and the combined energy is 96 (still weak, but the best of the bunch). The wind is super light from the northwest, nearly glassy – that’s a big plus for clean waves. The water temperature is pretty average for this time of year.

Other than that, Saturday morning the 15th has a clean, cross-offshore wind and a 2ft SW swell with a 6-second period (energy 53), but it’s still small.

So the only highlight is the morning of the 17th of August – a small, clean wave that’s fine for a longboard or a foiler, but don’t expect any punch. The rest of the window is a bust. It happens sometimes around here. Keep an eye on the forecast, though.
