The Lowdown

Alright, groms and regulars, Rusty here with the lowdown on the next couple of weeks. We’ve got swell on the horizon, but you gotta pick your moments. The real gold is at the end of the first week and then again in the second week.

To start, Saturday the 12th at Alnes Lighthouse. The water is 55°, dead average for the season. We get a clean 6ft west swell in the morning with a light cross-off breeze. Wave energy sits at a solid 739. A nice way to ease into it.

Saturday afternoon gets a little chunkier, with 8ft from the west, but the wind picks up to 16 mph from the south-southeast. It’s still rideable, but the morning is cleaner.

Sunday the 13th is a skunk. The swell hits 10ft from the west-northwest, but the wind is a messy cross-shore at 22 mph. Lumpy, choppy, not worth the hassle.

Now, Monday the 14th, that’s the sweet spot of the first week. Morning brings a clean 6ft north-northwest swell with a light cross-off breeze. But the afternoon is the money. Glassy conditions with a whisper of an east-southeast breeze. The swell drops to 6ft, but with that glassy surface, it’s pure, clean fun. Tuesday the 15th keeps the fun going with a smaller 4-5ft southwest swell and light offshore winds.

Wednesday the 16th and Thursday the 17th are dead. Short period swell, onshore winds, weak wave energy. Don’t even think about it.

Get ready for Friday the 18th. Big day. We get a 10ft west groundswell with a very long 14-second period. The wind is a clean cross-off from the south-southwest. This is powerful, heavy water. The wave energy is a massive 3272. Only for experts. The morning session is the one.

The weekend of the 19th and 20th is blown out again. Rain and strong cross-shore winds.

But then, Tuesday the 22nd afternoon delivers another standout. A moderate offshore wind from the south-southeast at 16 mph. The swell is a serious 12ft from the west with a 13-second period. Clean, powerful, expert territory. Wave energy is off the charts at 3495.

The wind gets wild again until Thursday the 24th afternoon. That’s another excellent call with a 13ft west-northwest swell and a gentle offshore breeze from the southeast.

And the winner for the entire forecast is Friday the 25th morning. Massive 13ft swell from the northwest, a very long 12-second period, and a light cross-off breeze. The wave energy is a staggering 4131. It’s clean, it’s huge, and it’s only for the brave. Friday afternoon is also beautiful, with a 10ft swell and almost no wind.

The last weekend, the 26th and 27th, settles back down to clean, smaller waves. Sunday the 27th afternoon looks glassy again with a 6ft west swell.

Best calls of the window: Monday the 14th afternoon for a glassy, all-levels gem, and Friday the 25th morning for the biggest, cleanest swell of the run. Get out there.

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.
