The Lowdown
Alright folks, Rusty here. Let's break down what the ocean’s got in store over at Alnes Lighthouse for the next couple of weeks. We're looking at a point break, and it's going to be a bit of a mixed bag, but there are a couple of windows that could be real sweet.
First thing, the water is sitting at a chilly 55°F, which is about 2°F colder than normal for this time of year. You'll want a thicker wetsuit for sure, but don't let that put you off.
The start is a tough slog. Monday and most of Tuesday are a complete write-off with poor conditions and messy winds. The first real sign of life comes Wednesday afternoon, August 12th. It’s tiny, only 2ft from the north with a short period, but that light easterly breeze is off the land, keeping it clean. The energy is low (99). It's barely rideable, just a chance to get wet.
Now, Thursday morning, August 13th, is our first proper highlight. A 4ft swell from the west-southwest pushes the energy up to a moderate 301, with a glassy offshore puff from the south. That wind is a game changer. It’ll be clean, lined-up, and perfect for an intermediate surfer.
Friday morning, August 14th, is the real standout of this entire forecast. We’ve got a 3ft swell from the west with a proper 11-second period, giving it real punch and shape. The wind is dead calm, flat glassy, and the energy is sitting at a solid 297. That’s the kind of combo that makes a point break absolutely cook. For a few hours, it’s going to be clean, rippable, and beautiful. Later that afternoon a bigger 6ft swell rolls in, but the period drops to a jumbled 6 seconds, and the wind swings onshore, turning it into a mess.
We hit a rough patch from Saturday the 15th through the start of the next week. The wind kicks up hard, mostly onshore or strong cross-shore, making things choppy and sloppy. There’s a pulse of 7ft swell on Sunday the 16th from the north-west with a 9-second period and strong energy (810), but with that onshore breeze, it’s going to be a tough, choppy mess. That's expert-only territory if you're bold, but not what I'd call fun.
Tuesday morning, August 18th, offers a tiny glassy reprieve: a 3ft wave (125 energy) with zero wind. It’s small and weak, but if you need a clean surface, it’s your only ticket.
The rest of the second week is a bit of a dud. The winds stay strong and unfavorable, and the wave heights stay small and weak, mostly under 3ft. There are a couple of glassy mornings on the 22nd and 23rd of August, with 3ft and 2ft waves from the west, but the energy is really low (236 and 47). You could take a longboard out for a quiet paddle, but the power just isn't there.
To sum it up: if you can only surf one session, make it Friday morning, August 14th. That glassy west swell with a long period is the absolute best on offer. Thursday morning the 13th is a solid runner-up for a clean, fun session. The rest is a waiting game or a longboard cruise.
Keep your eyes open, and never trust a forecast until you're in the water. This is Rusty, signing off.

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.
