The Lowdown
G’day, Rusty here, and I’ve got to be straight with you – the next couple of weeks are looking pretty grim for a paddle around Diano Marina. It’s one of those stretches where the sea just isn’t cooperating. The whole 16-day window is a real bummer, with no days that are genuinely worth getting excited about.
The forecast kicks off Monday the 17th of August and it’s a flat start. There’s a tiny 2 ft swell from the SW with a short period of 5 seconds, and the combined energy is a weak 13. The wind is a light cross-off from the north, but the waves are just too small and weak to surf. This theme of tiny, weak swell and poor conditions carries on through the week. Even when we get a bit more size, like Thursday morning the 20th with 4 ft swell from the SW, the energy is still only 85, and the wave comment calls it "surfable but very ordinary". It’s just not worth the effort.
Saturday the 22nd of August has a slightly better morning with 4 ft from the SSW and the energy climbing to 142, but it’s still described as "surfable waves but very ordinary conditions". The wind is light and cross-off, which is a plus, but the swell period is still a short 7 seconds, so the waves are gonna be weak and crumbly.
The best part of the whole forecast, and I mean the only one that even gets a whisper of a nod, is Sunday the 30th of August. The morning shows 6 ft of swell from the WSW with a period of 8 seconds and a combined energy of 548. That’s a big jump in energy, and with light cross-off wind from the NNE, the surf would be clean. But it’s still a long way off, and for a spot that’s described as "inconsistent", this is a promising but uncertain prospect. It’s a one-morning wonder, too – the afternoon drops right off.
The water temperature is a stunning 84°F, which is a massive 8° warmer than average for this time of year. That’s seriously unusual, so you’ll be swimming in a bath.
Honestly, for the whole 16 days, you’re looking at a long blank run. There’s one morning that might deliver something, but overall, it’s a waiting game. The forecasts can always change, but right now, I’d save the energy and wait for a better window.

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.
