The Lowdown

Right away, the ocean’s got some serious size on the way, but it’s gonna be a wild ride to get there. For the next few days, we’re staring at a lot of lumpy, cross-onshore slop that’s got no real shape to it. Monday the 14th is the first real glimmer of hope, but it’s small.

The standout of the whole run, without a doubt, is Alnes Lighthouse early on Sunday the 27th. That morning, the ocean cleans right up with a slight air, light cross-off wind from the SSW, and a solid 2.3m of W swell rolling in with a 12-second period. The combined energy is strong at 1649, and the water’s going to be glassy. This is the one to circle on the calendar – it’s promising, but it’s far out, so don’t book your flights just yet.

Before that, the water temp at Alnes is sitting at 13°, which is pretty much spot-on average for this time of year, so no surprises there.

That first clean window on Monday the 14th, we’re looking at 1.5m of NNW swell with a 10-second period. It’s clean, light offshore vibes, and the energy is moderate at 776. Fun for a grovel, not a world-beater. Tuesday the 15th keeps the clean theme going, but it drops to 1.1m with a shorter, weaker W swell – just mush.

Then the ocean goes a bit feral. Wednesday the 16th starts to get messy, and by the 20th, we’re looking at 4.5m of wind-blown chaos with near-gale onshores. That’s not surf, that’s survival. The energy jumps up to 5155, but it’s all chop and blown-out lines. That setup looks way more interesting for kite surfing than paddle surfing.

We’ve got a rough spell from the 16th right through to the 26th, with wind and swell fighting each other. There’s plenty of size, but it’s mostly cross-shore junk. The 24th sees a massive 4.0m of W swell, but it’s accompanied by strong cross-onshores and a messy, lumpy surface – no good.

So, the plan is simple: sit tight, watch the chaos, and aim for that Sunday the 27th morning window. It’s got the size, the period, and the clean conditions. It’s the only true standout in the whole 16-day run.

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.
