The Lowdown
Alright, let’s get into it.
Honestly, looking at the next couple of weeks, it’s a bit of a rough stretch for us here at Alnes Lighthouse. We’ve got a window opening up, but the ocean is going to make us work for it.
The water is sitting at 55°F, which is about 3°F colder than the long-term average for this time of year. You’re gonna want the thick rubber, no question about it.
The first few days, through the 18th, are basically a write-off. We’ve got wind all over the place, mostly cross-shore and cross-onshore, and the swell is just messy with a lack of direction. The energy is there in the water early on—it’s moderate, with a combined energy reading of 447 on Friday morning—but the conditions just aren’t cooperating. It’s all chop and lump, no good for a clean ride. Friday afternoon jumps up to 5ft, but the wind is up at 15 mph and it’s just poor.
There is a small gap around the 19th and 20th, but it’s not much to get excited about. Wednesday the 19th goes glassy with that 3ft to 4ft of north swell, but it’s short-period (8 seconds) and just feels ordinary. It’s surfable, but not something you’d get out of bed for.
The standout in this whole stretch, and I mean the only real standout, is Friday morning, August 21st. The wind drops out completely, leaving us with a glassy surface. The swell pushes up to 4ft, still from the north with an 8-second period, but the clean conditions will make a world of difference. The combined energy is moderate at 267, so there’s a bit of push behind it. This is the time to be in the water. It’s a point break, so that short-period north swell should line up a bit better than it would at a beach break, anyhow. Could be a bit inconsistent, but the clean face will be worth it.
After that, the wind swings onshore again, and the swell starts to fade out. From the 22nd all the way through to the 29th, there’s nothing but small waves and poor conditions. We’re talking mostly under 3ft, with the swell dying off completely by the last week. There’s some glassy pockets on the 27th, but the swell is just too weak to matter, with a combined energy barely getting into double digits.
So, here’s the deal: if you wanna get wet, mark your calendar for Friday morning, the 21st. It’s not a perfect swell, but the calm wind and the point break will make it the best thing we’ve seen all week.

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.
