Diano Marina Surf Forecast and Surf Report

G’day, Rusty here. Look, I’ll be straight with you – this stretch at Diano Marina is a tough one. We’ve got a 16-day window, but the first recommendation doesn’t pop up until the morning of Tuesday, the 4th of August. Before that, Monday the 3rd is a total write-off: no swell to speak of and choppy conditions. So we’re looking at a gap of about a day and a half with nothing to get excited about.

Alright, let’s get into it. The overall pattern is weak, with barely any energy pushing through. Most of the time, the combined swell energy is pitiful, often in the single digits (0 to 11), which is barely enough to move a sea lion, let alone a surfer. The waves are small – ankle to knee high at best – and the period is short, mostly around 3 to 5 seconds, meaning it’s messy wind-swell, not groundswell. The water temperature is sitting around average for this time of year, so no surprises there.

The best of the lot, and I mean the only real standout, is Saturday morning, the 8th of August. We’ve got a clean 2 ft from the SW with a period of 7 seconds, and a NNE breeze at 15 km/h making for cross-offshore conditions. The combined energy is a modest 34, which is weak but it’s the highest we’ll see. The wave quality won’t blow your mind, but it’s the most rideable sliver in the whole forecast. Sunday morning, the 9th, is also worth a look – glassy conditions with a 1 ft SW swell, period 6 seconds, and energy at 16. It’s tiny, but the glass makes it pleasant for a beginner paddle.

Honestly, Diano Marina is an inconsistent spot, and this forecast proves it. There are long gaps – like the 11th through the 14th of August – where there’s literally zero swell and just clean, empty water. The 15th and 16th throw up a couple of 0.3 ft to 1 ft crumbs, but nothing to write home about. The 18th of August morning has a 1 ft SSE swell with a clean cross-offshore wind, but it’s still weak (13 energy). For a beginner, the tiny glassy days are your best bet for a stress-free session, but don’t expect any power.

If you’re after anything more than a gentle bob, this setup might be more interesting for a kite surfer on the breezy afternoons than a paddle surfer. The swell is just too small and too short-period to do much with.
