The Lowdown
Alright, mates, Rusty here. Let’s break down what the ocean’s throwin’ at us for the next couple of weeks. It’s a bit of a slow start, but there's some proper gold in there if you're patient.
The next few days are pretty grim. Small, weak swell and onshore junk. You're not missing anything Thursday, Friday, or even Saturday morning. It’s the kind of slop that’ll have you questioning your life choices.
The real story starts Saturday. Swell bumps up to 6ft, wind turns light offshore. That’s a big turnaround. Water temp is 56°, right on the average for this time of year, so no surprises there. Saturday afternoon gets bigger, but the wind swings and it gets tricky. The real gem is Sunday – solid 6-8ft swell, offshore wind, and glassy. That’s a surf you won’t want to miss.
Monday sees the swell back off a bit, but it’s still clean with light winds and some glassy spots. It’s not as powerful, but it’s fun. Then things go flat and messy mid-week. The wind howls from the NNE and kills the vibe for a couple days. That's the lull.
The next standout is the following Friday. The swell jumps back up to 5-6ft with a longer period, and it’s glassy again. Another solid morning session. Saturday morning after that is also good, clean and glassy. It’s a pattern of good clean mornings, with afternoons getting lumpy with the sea breeze.
Things get properly serious the week after. From the 21st, it looks like a big pulse of west swell is on the cards. We’re talking 11-13ft. This is not for the faint-hearted. This is proper, hold on to your lunch, expert-only territory. The wind is offshore, so it will be raw and powerful. This is a big-time window for the crew who charge.
After that big push, it drops back but stays solid for a couple days. The 23rd has clean conditions and a solid 8ft of swell – a proper day for experienced surfers. But then the wind just goes nuts. The last few days of the period are blown out by a strong southwesterly. Not worth the effort.
So, in a nutshell, look at the mornings. The standouts for me are this coming Sunday and the following Friday morning. The big swell event around the 21st and 22nd is the one for the big-wave chargers, but it’s risky and only for the experienced.
Alright, that’s the long and short of it. Stay stoked.
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.
