The Lowdown
Alright folks, Rusty here. Let’s have a look at the next couple of weeks at Alnes Lighthouse.
It’s a bit of a slow start, honestly. We’ve got a few days of messy, onshore wind and lumpy conditions that just aren’t worth paddling out for. The first real glimmer of hope shows up on the 14th of September. Monday morning looks like a proper little gem – a clean 5ft NW swell with a light offshore SSE breeze. The wind will be glassy, the waves will have shape, and you’ll get that long-period energy (10 seconds) pushing through. The combined energy is moderate, and it’s not going to be too big for the average surfer. This is the standout window: Monday morning and Monday afternoon are both clean with that offshore/cross-off flow. Crowds are possible here, so get in early.
The 16th of September is a big one for the experienced crew. Wednesday afternoon sees a solid 12ft NW swell going glassy with the wind turning to almost nothing. The combined energy is strong, and the conditions are described as excellent for experienced surfers. If you’ve got the skills and the board for a big groundswell, this is your window. The period is 10 seconds, so it’s a solid, powerful wave. This is the second standout.
The rest of the first week is a write-off – strong winds, lumpy cross-chop, and onshore junk. The following week shows a bit of promise on the 20th of September: Sunday morning with a clean 4ft W swell and a light cross-off breeze. The combined energy is moderate, and it’s a nice, clean option for a morning session. Keep an eye on the 22nd of September as well – Tuesday morning could be very good with a 5ft W groundswell, a 12-second period, and clean conditions, but that’s a long way out and might change.
Water temp is about what you’d expect for this time of year, so wetsuit up as usual.
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.
