The Lowdown
Alright, let's break it down for Diano Marina. I'll be honest – it's a grim stretch for the most part. You're looking at nearly a week and a half of next-to-nothing, then one brief moment of something decent, then back to flatness.
Starting off Tuesday 25th August, it's flat and glassy with a tiny 1ft southerly swell, but the surf is poor. That theme sticks all the way through Friday 28th August. There's a little energy here and there, but wave heights are all under 3ft, periods are short around 4 to 6 seconds, and the wind is mostly cross or cross-on. Nothing for a surfer. The water is a warm 82°F, which is much warmer than normal – 7°F above average, so that's very unusual.
Then there's a gap of flat days from Thursday 3rd September through to Friday 5th September morning – just zeros.
The one real standout hits on Saturday 29th August morning. Out of nowhere, we get a 6ft swell from the SSW, with a 6-second period, and the combined energy hits 311 (moderate wave energy). The wind is offshore from the NW at 3 mph, so it's clean. This is your best bet – solid head-high surf at Diano Marina with light offshore winds. It's going to be a good session, but this spot is inconsistent and the crowd can show up sometimes. This size is fine for most, not too big.
After that Saturday morning window, it drops back to small, weak, and messy for the rest of the forecast. Saturday afternoon goes onshore and tiny, and then it's back to the same poor-quality stuff through until Tuesday 8th September. There's a little bump on Monday 7th September morning – 2ft SSW with a 5-second period and clean cross-off wind – but the energy is only 20 (weak). Not worth getting excited about.
So, bottom line: you've got one morning to go – Saturday 29th August – and then it's a long wait. For this area, a blank run is more normal when the swell windows are this narrow. Don't lose hope, forecasts can change.

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.
