The Lowdown
Alright, Rusty here, and I'm staring down a pretty bleak stretch of forecasts for our local lineup. For Alnes Lighthouse, we’re in for a real test of patience.
The first week is, frankly, a bust. From Friday, August 28th, right through until Thursday, September 3rd, you can leave the boards in the garage. The swell is tiny, the wind is all wrong, and the water temperature is a pretty normal 57°F. It's all weak, short-period windswell with barely any energy – the combined energy levels are well under 100 -- and the cross-shore and onshore winds are going to turn everything into a washing machine. It's a full seven days of nothing.
There’s a slight break in the clouds on Friday afternoon, September 4th. The swell is a pathetic 2ft from the WSW, but the wind goes dead glassy. It will be rideable but very ordinary. It’s a one out of ten kind of day.
The only real window of opportunity comes on the weekend. Saturday, September 5th is our best shot. The swell builds to a clean 4ft from the west with a proper 11-second period – that’s groundswell, and we can feel the energy jump to 396. The wind turns clean and cross-off from the south. That west swell is a bit north of the ideal direction, but with that offshore breeze, this is the standout morning of the whole outlook. Sunday morning, September 6th, brings a bigger pulse – 7ft from the west – still with clean wind, but that’s getting into big-wave territory for most.
Into the second week, the consistency falls apart. Monday morning, September 7th, is glassy with a 4ft west swell, but then the wind goes onshore. The rest of the week is a mixed bag. Tuesday the 8th has a glassy afternoon with a 5ft swell, but the period is short at 7 seconds, so it’s fat and weak. The real far-out hope is Saturday, September 12th. That morning shows a solid 7ft swell from the NNW with a 10-second period and a clean cross-off breeze. The energy is strong at 990, and it scores a three out of ten – the highest score of the whole period. It’s promising, but it's so far out you can't bank on it.
So, keep your eyes on Saturday, September 5th. It's the only clear winner. A clean 4ft west groundswell with a cross-off wind at Alnes Lighthouse is as good as it’s going to get. Sunday morning is for the brave on the bigger boards. Everything else is a long shot.
Hang in there.

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.

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.
