The Lowdown
Alright, Rusty here with a look at what we've got coming down the line at Alnes Lighthouse (Norway) . It’s a point break that’s fairly exposed, picking up swell best from the northwest. Things are pretty quiet to start, so we’re looking at a bit of a slow burn before anything worthwhile shows up.
The water’s sitting around 55° – a bit colder than normal for this time of year, so you’ll want that rubber buttoned up tight.
We’ve got a rough start on Friday the 21st with some rain and a lumpy 6ft to 6ft swell out of the NNW. The wind’s on it and messy, so honestly, it’s not worth paddling out. That theme carries through the weekend. Saturday morning sees the swell drop to 4ft from the north with a cross-onshore breeze – choppy and poor. The period’s a short 7 seconds, so no grunt behind it. That trend of small, weak, and windy continues right through until Tuesday the 25th.
Things look a little calmer early on Wednesday the 28th. We get a proper offshore wind from the southeast, cleaning up a 3ft wave from the north. The energy is moderate (247), and it’s got a 9-second period. It’s surfable, but it’s only ordinary, not a standout.
The real highlight, and the one to circle on the calendar, lands on Saturday the 5th of September. The afternoon session is looking very promising. We’ve got a solid 8ft swell from the north hitting the point. The combined energy is strong (833), and the wind flips to a light cross-offshore from the east-northeast. That should clean it right up into proper, lined-up waves. Period is 8 seconds, so it’s a decent push, though at that size it’s one for the experienced crew – beginners will want to sit this one out.
Sunday the 6th morning might also be worth a look if you can get out before the wind changes, with a 8ft north swell and a light cross-onshore breeze, but the Saturday afternoon is the clear winner.
Otherwise, the first week is a write-off, and the tail end of the forecast is too small to bother with. Keep your eyes on that Saturday the 5th.
Rusty.

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

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 Alnes Lighthouse 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.
