The Lowdown
Alright, Rusty here. Let’s have a look at what’s on the cards for Diano Marina.
To be straight with you, this forecast is a tough one. We’re looking at a long, dry spell with nothing worthwhile for a paddle. The first real chance of any wave energy doesn’t show up until Wednesday the 16th of September, and even then it’s barely a pulse. The water is sitting at a very unusual 81°, which is far warmer than normal for this time of year, but that’s about the only excitement.
From now until Wednesday morning, it’s flat. A few tiny ripples appear on the 11th and 12th, but with swell heights of just 0.3ft to 1ft and short periods around 4 to 6 seconds, the combined energy is negligible (1 to 5). The wind is light and variable, but there’s simply no swell to work with.
The first sign of life comes on Wednesday the 16th. The morning shows a glassy 1ft SW swell, but it’s weak (combined energy of 6). The afternoon picks up a little to 2ft from the SW with a period of 4 seconds, but the onshore wind from the SSE makes it messy. Still, it’s a start.
Thursday the 17th sees a slight bump. The morning has a 2ft S swell with a period of 5 seconds and a clean, cross-offshore NNE breeze at 9 mph. The combined energy hits 32 – weak, but it’s the best we’ll see. The afternoon turns choppy with a cross-onshore wind.
After that, it fades back to tiny, inconsistent leftovers through to the end of the 16-day window. The weekend of the 20th has a few 1ft to 2ft swells, but the winds are mostly onshore or cross-onshore. The surf quality remains poor throughout the entire forecast. There’s nothing that even comes close to a standout session here.
Honestly, this stretch looks better for a swim or a paddleboard than a surfboard. The waves are too small and weak for any real fun, and the setup at Diano Marina, being an exposed beach break, just isn’t getting any love from the ocean. It’s a blank run, which is normal enough for this area in these conditions. Forecasts can change, but for now, keep the boards 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.
