The Lowdown
Alright crew, Rusty here with the skinny on this stretch of coast.
We are looking at a dead calm start. The first wave worth paddling for is a full week away. The water is real warm—about 83°F, way toastier than usual for this time of year, but you won’t be surfing it just yet.
The wait ends on Friday morning, August 28th. Diano Marina is the only game in town. A solid 8ft SW swell rolls in with a short 7-second period, packing a strong 623 energy rating. Wind is a steady 19 mph cross-offshore from the WSW, keeping the surface clean. That’s a decent-sized wave, a little too much for beginners, and that short period means it will be lumpy and less organized. It’s a challenge for the experienced. The afternoon gets blown out by a 28 mph cross-shore.
The real highlight is Saturday morning, August 29th. The SW swell drops to a much friendlier 4ft, still short-period at 8 seconds, with a moderate 221 energy reading. The wind goes light offshore from the NNW at just 6 mph, creating nearly glassy conditions. Diano Marina is exposed to the south, so it catches that south-west groundswell. For intermediates, this is the one. Crowds are a definite possibility, so set your alarm.
After that, it’s back to dribble until Friday morning, September 4th, when a 4ft SW swell with a 6-second period and 108 combined energy shows up. Wind is light cross-off from the north. It’s surfable, but ordinary at best.
Bottom line: If you want a wave, Saturday, August 29th is your only real bet. Clean, small, and with an offshore wind, Diano Marina will be the place to be. The rest of the forecast is a flat, washed-out mess.
Rusty out.

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.
