The Lowdown
Right, grab a coffee and listen up. Rusty here. I've been staring at the charts for our local patch, and I'm not gonna lie to you, it's a tough watch. We're staring down a proper flat spell.
The first week and a half is basically a write-off for anything you'd call surfing. You're looking at a long gap of several days with absolutely nothing on the table. From the start of the period right through to the morning of Sunday, August 23rd, the wave energy is practically non-existent, with readings in the single digits (1). The swell is almost non-existent, and when a tiny bump shows up, it's usually accompanied by a cross-onshore breeze that just messes it up. A few mornings are glassy, but with zero swell, that's just a nice view.
Finally, on the morning of Sunday, August 23rd, there's a flicker of life. Diano Marina will see a small, clean 3ft swell from the SW with a short period of 6 seconds. The wind goes glassy (light airs), which is a major win. The combined wave energy is a modest 61, so it's weak, but it's the best we've got. The water temp is pretty average for the time of year, nothing to write home about. It’s a small, clean wave for a beginner, but it's inconsistent and only just surfable. Still, after all that nothing, it feels like a gift. The wind stays clean on Monday morning the 24th but the swell drops away quickly.
For the rest of the outlook into late August, it’s a rinse and repeat of tiny bumps and onshore junk. Tuesday the 26th has a morning window with a clean 2ft from the SW (period 7 secs) but the energy is still weak (26). It's a grind.
The standout, if you can call it that, is that Sunday 23rd morning session. It's the closest thing to a winner on the whole 16-day card. Everything else is for the kite crew when the wind picks up.
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.
