The Lowdown
Alright, let’s get real about the surf over the next couple of weeks. I’ve been staring at the charts and honestly, it’s a struggle for most of the period. We’ve got a long, quiet gap before anything half-decent shows up on the horizon.
Things start off pretty weak. Thursday the 20th delivers a messy 3ft SSW swell, but that’s accompanied by thunderstorms and a strong cross-breeze. It’s not worth your time. That theme sticks around for days.
We’ve got a stretch from the 20th through pretty much the entire next week where the energy is low, the wind is often cross or onshore, and the general vibe is “poor.” There’s a brief moment on the morning of Friday the 21st with a glassy surface on a 4ft SW swell, but the energy is weak (combined energy of all swells directed here: 75) and the period is a short 5 seconds. That’s barely a bump, and the session would be for the patient.
You’re looking at a long, drawn-out gap with no real recommendations until we get to Friday the 28th of August. That morning, the swell finally starts to push up to 5ft from the SW, with a period of 6 seconds and moderate energy (186). The wind is offshore from the WSW, so it’ll be clean. It’s still nothing to fly a flag about, but it’s the first time we see some potential. That afternoon, though, the wind cranks up to 28 mph from the SW, making a mess of the 6ft swell. That’s expert territory on the size, but with that wind, it’s not user-friendly.
The one window that stands out as the best of a pretty quiet run is the morning of Saturday the 29th of August. We’ve got a clean 4ft SW swell, light and glassy conditions with an offshore breeze from the NW (combined energy: 113). The period is still short at 6 seconds, so the waves will be a bit lumpy and fat, but the lack of wind means you’ll be surfing your own lines. Diano Marina will be the spot to check, for those who don’t mind a bit of work for a couple of rideable waves. The water temperature is a balmy 83°, which is much warmer than normal for the time of year, so you can leave the thick wetsuit at home.
After that, it drops right back off again. We see a tiny nudge on Friday the 4th of September with a 4ft SW swell, clean morning wind, but the energy is low (94) and the period is 6 seconds. It’s a last little gasp before the lull sets in again. For now, keep the board in the car and hope the forecasts get better.

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.
Diano Marina is 4 km (2 miles) from Imperia. If you plan a holiday in West Coast of Italy, look for hotels and other accommodation in Imperia. Imperia has rooms for a wide range of budgets as well as car hire and transport links.
