The Lowdown
Alright, let’s break it down. The next couple of weeks are a mixed bag. We’ve got some moderate swell on the way, but the wind is gonna be a real pain for a lot of it. The first real chance of a wave comes on Sunday morning, August 9th, but it’s a tough one to call.
We’re looking at Alnes Lighthouse (Norway) as the main spot. This is a point break, which is a good thing because when we get that longer period groundswell, it handles it better than a beach break. The water temp is sitting at 56°, which is about 2° colder than normal for this time of year, so you’ll want a good thick wetsuit.
Sunday morning kicks things off with a 6 ft swell from the WSW, but it’s a short period, 9 seconds. The wind is a cross-off from the SSW at 15 mph, which is decent for keeping the surface clean, but the real kicker is the heavy rain. The combined energy is moderate at 620, so there’s some push there, but the conditions are just marginal. This one is more for the keen locals who don’t mind a bit of a drenching.
By Sunday afternoon, the wind swings onshore and picks up to 22 mph from the SW, absolutely ruining the surface. The swell is still there at 6 ft, but the cross-chop is going to be a mess. Not worth paddling out.
Monday, the 10th, is a write-off. Strong onshore winds and a messy cross-chop. The swell is around 7 ft, but you’ll be battling a 25 mph wind. Forget it.
The real standout window looks like Wednesday morning, August 12th. The swell drops to a clean 3 ft from the NW, with a period of 7 seconds. The wind goes light, cross-off from the SSW at only 3 mph. The energy is weak at 126, but the conditions are clean. This is a small, fun session for the longboard or a fish. The afternoon is even better, with glassy conditions and a 3 ft swell from the WNW. It’s small, but it’s the most user-friendly wave in the whole 16-day forecast.
Thursday the 13th looks promising too. Morning brings a 4 ft swell from the WSW (8 seconds) with light cross-off winds from the SW at 6 mph. The energy is moderate at 331, and the conditions are clean. This is probably the best compromise of size and quality. The afternoon jumps up to 8 ft, but that’s getting a bit big for the average punter, and the wind is a bit lighter. Still, for the intermediate surfer, this could be a solid session.
After that, the wind turns ugly again. From Friday the 14th through to the middle of the following week, it’s a steady diet of cross-shore and onshore winds, making everything choppy and lumpy. There’s a pulse of 8 ft swell on Thursday August 20th, but with 19-22 mph onshore winds, that’s a kite-surfing dream, not a paddle-surfing one. The energy is very strong (1703), but the direction and wind will ruin it for a surfer.
The last few days of the forecast, from the 21st onward, drop back down to 3 ft to 4 ft, with the wind still mostly cross-on. It’s small, ordinary, and not worth getting excited about.
So, to wrap it up: the best bets are the Wednesday morning (August 12th) for the cleanest, smallest conditions, and Thursday morning (August 13th) for a bit more size with still clean conditions. After that, it’s a waiting game for the wind to play nice. The forecasts can change, so don’t write the whole fortnight off, but be ready to be picky.

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. If you surf the same spot (Alnes Lighthouse) 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 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.
