The Lowdown
Alright, Rusty here. Let’s have a look at what we’ve got coming up.
Honestly, mate, it’s a bit of a flat spell for Alassio. The whole 16-day window is pretty quiet. The water is sitting at a balmy 82°, which is far warmer than normal for this time of year – you won’t need a wetsuit, that’s for sure. But the waves? They’re tiny.
The first recommendation kicks off on Friday the 11th of September, but it’s not much to write home about. We’ve got a tiny 1ft swell from the south with a period of 5 seconds, combined energy of just 13 – that’s weak. The wind is a cross-off from the NNW at 3 mph, so conditions are clean, but the waves are too small and weak to really surf. It stays like this through Saturday and Sunday, with swell dropping to nothing by Sunday.
Monday the 14th through Wednesday the 16th is almost totally flat, with zero swell and glassy or light winds. On Thursday the 17th, there’s a slight bump: a 2ft south swell, period 5 seconds, energy 17. That’s still tiny. The morning has a risk of thunderstorms and an offshore wind from the NW at 6 mph, so it’ll be clean, but the waves are barely a ripple.
From Friday the 18th right through to the end of the window on Saturday the 26th of September, it’s almost all flat. The biggest swell we see in that stretch is 1.0ft on Saturday the 19th afternoon, with a 5-second period from the SE. Winds are cross-off from the NE at 9 mph, so clean, but again, nothing to surf. There’s a faint pulse on the 26th with a 0.3ft south swell showing a long period of 12 seconds, but with energy of only 4, it’s not going to do anything.
Bottom line: there are no standouts. The whole period is a bust for surf. If you’re desperate, the morning of Thursday the 17th offers the most swell at 2ft with clean offshore wind, but that’s it. For the rest of the time, you’re better off enjoying the warm water and the sunshine. The setup here looks more interesting for kite surfing than paddle surfing given the persistent small, weak swells and occasional cross-off breezes.
Stay patient, mates. It won’t stay flat forever.

Information about the Alassio Surf forecast
The above surf forecast table for Alassio provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Alassio can be found by selecting the local surf guide option on the grey menu. Our Alassio 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 (Alassio) 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 Alassio 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.
