The Lowdown
Alright folks, it’s Rusty here. Let's take a look at what's on the cards for the Alnes Lighthouse stretch. To be honest, the immediate outlook is a bit of a head-scratcher. We’re looking at a solid 16-day window, but the first real glimmer of decent surf doesn't show up until late in the piece. The first week and a half is pretty much a write-off, with a lot of wind-affected, choppy, and marginal conditions. The energy is there, but the quality just isn't.
The first period that’s worth a mention lands on Friday the 14th of August. That afternoon, we get a bit of a reprieve from the wind. The swell drops right down to 3ft from the WSW, with a period of 10 seconds, and the wind goes glassy. The combined energy sits at 232 (moderate), so it’s small but it’ll be clean. That’s a small window of opportunity for a longboard or a funboard, but the wave comment says "surfable waves but very ordinary conditions," so keep your expectations low.
The next noteworthy moment is a whole week later, on Friday the 21st of August. The morning session sees a glassy morning with a 4ft swell from the north, period of 7 seconds, and 178 (moderate) energy. It’s not going to be a world-beater, but glassy conditions can make anything fun. Then that afternoon, the wind goes completely dead calm, with a tiny 2ft westerly swell and a 10-second period showing 126 (moderate) energy. That’s another opportunity for the clean but small wave crew.
Now, the standout of the entire forecast comes much later, on Wednesday the 27th of August. Thursday morning is the one. The forecast shows a glassy morning with a 5ft swell from the north, with a period of 8 seconds. The combined energy is 250 (moderate). The wave comment honestly says "surfable waves but very ordinary conditions," but compared to the noisy, windblown junk we’ve been seeing, this is the best of the bunch. That 5ft with glassy conditions is going to be the cleanest, most user-friendly wave of the whole 16 days. The water temperature is likely about average for the time of year, nothing too wild.
Forget the rest of the window. The near gale-force winds on the 28th of August are a hard pass. Your best bet is to circle the morning of the 27th of August and be ready for a clean, fun session at Alnes Lighthouse.
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.
