The Lowdown

Alright, Rusty here. Let's have a look at what's shaping up for Alnes Lighthouse.

Straight off the bat, we've got a bit of a wait on our hands. The next couple of days are a write-off with strong cross-onshore winds and lumpy surf, so don't bother paddling out just yet. Things start to turn around on Monday the 14th.

Monday morning sees a clean-up with light cross-offshore winds from the SSW, and a drop in swell to a clean 5ft from the NNW. The energy is moderate (901), but the conditions are looking very good. By Monday afternoon, it goes glassy with no wind, and a 5ft NNW groundswell. That's a solid, clean combo for a point break, and with the swell direction coming from the NNW, it's a good match for the spot. The water temp is about average for this time of year.

Tuesday the 15th keeps the good vibes rolling with clean conditions and a smaller 4ft swell from the west, but the period drops to 9-10 seconds, so the wave quality is still there, just less punchy.

The real standout, the one to circle on the calendar, is Friday the 18th. Friday morning delivers a very long-period groundswell from the WNW at 5ft with a period of 16 seconds. The energy is strong (1400), and with clean cross-offshore winds, this is excellent surf for experienced surfers. The long period will see the swell wrapping nicely around the point at Alnes Lighthouse. Friday afternoon gets bigger to 8ft from the west, but with stronger winds, it becomes more of a handful.

Saturday the 19th holds solid at 6ft to 8ft from the west/southwest, but the winds are a bit stronger, keeping it from being perfect. Still clean, but the quality takes a slight hit.

Then we hit a big, angry pulse. Sunday the 20th and Monday the 21st see a massive swell, hitting 13ft to 15ft, but it's accompanied by gale-force winds and poor conditions. That's not for paddling. A setup like that is more interesting for the kite crew than anyone on a surfboard.

After that blows through, Tuesday the 22nd afternoon and Wednesday the 23rd become the second major highlight. Tuesday afternoon sees a 12ft WNW swell cleaning right up with light cross-offshore winds and strong energy (2473). That's excellent surf for experienced surfers. Wednesday morning is the absolute gem: glassy, 13ft from the NW, with no wind at all. The energy is very strong (2653). If you've got the skills, that's a session you won't forget, but it's a proper big-wave affair. Wednesday afternoon drops back to a more manageable 5ft, still glassy.

From the 24th onward, the surf fades out. Thursday and Friday are small and weak, though Friday the 25th afternoon offers a final flash of glassy 8ft surf from the west, which is worth a look for a clean, smaller session.

To wrap it up: the best bets are the Monday 14th cleanup, the Friday 18th morning long-period groundswell, and the Tuesday 22nd afternoon through Wednesday 23rd glassy, big-wave window. The crowds can show up at Alnes Lighthouse sometimes, so get in early for the standouts.

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.
