The Lowdown
G’day, Rusty here. Let’s break it down. The next two weeks have a bit of everything, so you’ll want to pick your windows carefully.
We start with a clean little run on Monday morning at Alnes Lighthouse. Light cross-off breeze, 1.5m from the NNW with an 11-second period. Water temp is about average at 13°, nothing wild. It’s a fun, easy start. The glassy afternoon drops to 1.3m, still good for a quick paddle if the banks are your friend.
Tuesday keeps the clean lines going – 1.1m from the west with a light offshore, both morning and afternoon. Periods are in the 9-10 second range, so not groundswell, but it’s playful. Wednesday gets ugly early – strong onshore winds and lumpy, so that’s a rest day.
Thursday brings the glass back with 1.5m from the NNW but a shorter 8-second period. It’s surfable but not the standout. Then comes Friday the 18th – that’s your first real highlight. Morning has 1.9m from the west with a 16-second period (energy at 1895), light cross-off breeze, and clean conditions. That’s a cracker for experienced surfers. The afternoon bumps to 2.1m with a 14-second period, but the cross-shore wind puts a little wobble on it. Still, Friday morning is the one to chase.
The weekend turns scratchy. Saturday has offshore wind but it’s strong, then the afternoon gets lumpy. Sunday sees the swell up to 3.0m at 10 seconds with a near gale cross-shore on the afternoon – that’s kite territory, not a paddle.
Monday the 21st kicks things up a notch – 4.5m of west swell with a 13-second period (6635 energy), but it’s full-on messy with strong cross-onshore winds. Choppy and raw. The rest of that week stays poor – Tuesday, Wednesday, Thursday all have onshore or chop issues, with waves dropping to 0.8m – 1.7m. Nothing worth getting wet for.
Now, the big one to watch is Friday the 25th. It’s a long way out, so take this with a grain of salt, but it’s promising. Morning sees 2.4m from WNW at 17 seconds (3840 energy), with a fresh cross-off breeze and clean surface. Afternoon blows up to 3.5m at 16 seconds (5725 energy), still clean but pushing expert limits. If it lines up, this could be the best day of the whole stretch – but don’t lock it in yet.
The following Saturday (the 26th) still has solid 2.1m from the west in the morning, but the wind is cross and it gets messy. Sunday drops off.
A word on this break – it’s fairly exposed, so when the swell goes over 2.5m, you need to know what you’re doing. Crowds can show up only sometimes, but the big swells will bring the crew out.
So, bottom line: your best bet is Friday the 18th morning for a clean, solid session. Then, for the experienced crew, keep an eye on Friday the 25th – that could be the one, but it’s a gamble at this distance.
Stay sharp.
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. 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.
