The Lowdown
Alright, Rusty here. Let’s take a look at what’s coming up for Alnes Lighthouse.
Right off the bat, we’ve got a bit of a quiet start. The first couple of days are a write-off with small, weak, poor surf. It’s not until Wednesday the 2nd that we see something worth paddling out for, but even then it’s marginal. That morning, we’re looking at a 6ft swell from the WSW, period 9 seconds, and the cross-offshore wind from the SW at 18 mph will keep things clean. The wave energy is moderate (679). By the afternoon, the swell jumps to 8ft, which is getting into expert-only territory, with the same cross-offshore wind but a fresh breeze. The energy is strong (1092). It’s a bit of a rough start, but it’s something.
Thursday the 3rd is a step down again. The morning has 4ft from the W (period 7 seconds) with a light cross-offshore breeze – clean but ordinary. The afternoon turns glassy with a 4ft, 8-second swell from the N. Still, it’s just surfable, nothing special.
Now, the standout. Saturday the 5th afternoon is where it’s at. The swell picks up to 6ft from the W, with a period of 12 seconds – that’s a proper groundswell, with good energy (976). And the wind? Glassy, with a slight air from the NNW. That’s going to be clean, lined-up waves. For a point break like Alnes Lighthouse, this long-period swell will wrap in nicely. It’s an intermediate-level spot, but with that size and quality, it’s the best on offer. The crowd factor is “sometimes,” so you might have company, but it’s not a zoo.
The rest of the period is a mixed bag of poor conditions, strong winds, and messy surf. The 7th and 8th get blown out with near-gale force winds and big, junky swell. The 14th has a morning of glassy 3ft NW swell, but it’s ordinary. The 16th morning has a tiny 1ft, 12-second groundswell from the NNE, glassy, but it’s barely surfable.
Water temperature? No anomaly given, so it’s about average for the time of year.
Overall, keep your eyes on that Saturday afternoon. That’s the one.
Rusty.

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.
