The Lowdown
Right, mate, Rusty here. Let’s look at what Alnes Lighthouse has cookin’. This is a point break, fairly exposed, and it wants a northwest swell to do its thing. The water’s sitting at 56° right now, which is pretty much bang on average for this time of year, nothing weird going on there.
We’ve got a bit of a flat start, but things kick off proper on Saturday the 12th. The morning is looking sweet – we’ve got a 7ft swell rolling in from the west with an 11-second period, and the wind is blowing offshore from the SSE at 9 mph. That’s clean, lined-up surf with moderate energy (935). It’s a bit solid for beginners at that size, but for intermediates, it’s a real good look. The afternoon holds 7ft and cross-off winds, still clean and punchy with strong energy (1445). Saturday is the standout of this first week.
Sunday the 13th gets messy. The swell pushes up to 10ft from the WNW, but the wind swings onshore and blows a solid 22 mph. That’s a lot of energy (2128 in the morning, 2689 in the arvo) but with that much wind, it’s gonna be a lumpy, choppy mess. Only for the gnarliest crew, if anyone.
We get a break in the wind on Monday the 14th. The swell drops a touch to 8ft from the NNW, and with light southerly cross-off winds at 6 mph, it cleans up nicely. That’s a proper groundswell (12-second period), and while the energy is still strong (1596), the longer period will make for some long lulls between sets. At a point break, that’s a good thing – you get your breath back. This is a solid call for experienced surfers.
Tuesday the 15th morning is another good window – 6ft from the west, 11-second period, and a gentle 9 mph offshore from the SE. Clean, fun, and not as heavy (726). The afternoon turns to slop with fresh onshore wind.
After that, we hit a few days of ordinary, onshore conditions, lumpy cross-chop, or just small and weak. The swell drops down around the 3ft to 6ft mark, but the wind is rarely your friend.
Then, hold onto your board. The real standout is Thursday the 24th. The afternoon brings a proper pulse: 10ft of west swell with a 15-second period, and light cross-off winds at 6 mph. The energy reading is massive at 4356 – that’s serious power. This is an excellent, clean, heavy groundswell. For experienced surfers only, this is the best on offer in the whole 16 days. The morning of the 25th also looks great: 8ft from the west, 13-second period, and glassy offshore winds from the SE. That’s another cracker for the experts (2141). Crowds are sometimes an issue here, so on these days, you might have some company, but the waves will be worth it.
So, overall: the first week has a couple of good days, with Saturday the 12th and Monday the 14th being the picks. The second week has a bit of a quiet spell, but the last couple of days – the 24th and 25th – are the real heavyweights. That Thursday and Friday are the ones to circle on the calendar.
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.
