The Lowdown
Alright, grab a coffee and listen up. Rusty here.
First off, I gotta be straight with you – the next week and a half is a bit of a write-off. We've got a long stretch of nothing from now until the morning of the 21st of August. I'm talking flat spells, tiny wind slop, and a whole lot of staring at a glassy but empty ocean. The water is a balmy 84° at Diano Marina, which is much warmer than normal for this time of year, but that's about the only highlight.
The first real pulse of energy shows up on the morning of Friday the 21st. A small SW swell pushes in at 4ft, but it’s a short period 7-second affair. The combined energy is moderate at 131, but don't get too excited. The morning looks clean with a light offshore, but the afternoon gets ruined by a strong 16 mph cross-onshore wind making it choppy. It’s surfable, but very ordinary.
After that, it’s back to the doldrums for a few more days. Things get a little more interesting towards the end of the window. The morning of Tuesday the 25th sees a 3ft SSW swell with clean conditions. Then on the afternoon of the 25th, the swell bumps up to 5ft from the SW, with a combined energy of 133, but the wind swings light onshore, so the quality will be a bit bumpy. The stand-out is the morning of Wednesday the 26th. The same 3ft SW swell is still running, the energy is moderate at 61, and we get clean conditions with a cross-offshore breeze. It’s not a world-class day, but compared to the rest of the window, it’s the best on offer for a few clean, small waves.
Honestly, if you’re itching for a paddle, wait for the morning of the 21st or the 26th. The rest of the time, the board stays in the car.
Rusty.

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