The Lowdown
Alright, folks, let’s get into it. I’ve been looking at the forecast for Diano Marina, and I’m not gonna lie to you—it’s pretty bleak for the next couple of weeks. We got a long stretch of nothing coming up, so don't get your hopes up.
From Sunday the 9th all the way to Monday the 17th, it’s flat. We're talking swell heights at 1ft or less, and the combined energy is in the gutters, mostly single digits and zeros. The water’s real warm though, coming in at about 84°F, which is a solid 8°F warmer than usual for this time of year. That’s a big anomaly, feels like a hot tub, but it doesn’t help the waves. Morning winds are light offshore, but there's just no swell to work with.
The first sign of life shows up on the morning of Monday the 17th. The swell climbs to 2ft from the southwest with a period of 5 seconds, and the energy gets to 18. It’s still junky, but it’s something. The afternoon adds a little more size to 2ft, but the period drops and the energy stays weak. The wind goes onshore, so it’ll be messy.
Then, the one real window opens on the morning of Tuesday the 18th. The swell bumps up to 4ft from the SSW with a period of 6 seconds, and the combined energy jumps into the moderate range at 174. This is the highlight of the whole 16 days. Winds are light and cross-offshore, so it should be clean. But remember, Diano Marina is an exposed beach, and with that short period, it’s going to be lumpy and probably closing out. It’s not a classic, but it’s all we got. The afternoon fades to 3ft, so get it while you can.
After that, it’s right back to nothing. The rest of the week and the weekend are flat and weak. There are some long-period pulses, like a 10-second swell on the 19th, but it’s only 0.7ft. Not even worth the walk.
So, bottom line: this is a long, flat spell. If you’re desperate, Tuesday the 18th is your only real shot, and even then, it’s just ordinary. For beginners, 4ft on a beach break might be a bit much, so maybe skip that one. For everyone else, it’s a strong maybe. Otherwise, keep the board in the car and enjoy the warm water.

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.
