The Lowdown
Alright, grab your wettie and listen up. It’s Rusty here, and I’ve been staring at the charts for Alnes Lighthouse for the next couple of weeks. Honestly, it’s a bit of a tough stretch ahead for paddle surfing. The long-range outlook is promising in terms of consistency, but the immediate future is a whole lot of wind and chop messing things up.
Here’s the deal. The bulk of this 16-day window is going to be a write-off for clean waves. We’ve got a lot of days where the swell is there, but the wind is mostly cross-shore or cross-on, and often blowing hard. That’s going to leave the place lumpy and messy. There are a few moments of calm, and those are the windows we need to be watching for.
This first week is a real patience test. The energy in the water is weak to moderate, with the combined energy reading around the 150-200 mark. We see swell up to 6ft, but it’s all being blown out. You’ll see poor conditions dominating, day after day. The strongest pulse is around the 20th of August, with combined energy hitting over 400, but the wind is kicking up to 28 mph. That’s not surf, that’s a washing machine. A couple of days later, on the 23rd, a very brief window shows up. The wind drops to nothing for Monday afternoon, giving us glassy conditions and about 3ft of swell. It’s surfable, but it’s very ordinary, nothing to write home about.
Now, for the true standout in this otherwise bleak forecast. Look at Monday, the 17th of August, in the morning. The data shows a brief moment where everything aligns. The wind is from the NNW at 3 mph, which is essentially glassy. That’s a major positive. You’ve got 2ft of swell coming from the north with a 9-second period, which is okay. The energy is still weak (159), but for this break, that’s when the quality is going to be at its peak for the entire forecast. This is the best on offer. Get out early because the afternoon sees the wind swing to the NNE and howl up to 16 mph, wrecking it instantly.
After that, it’s back to the grind. We go through a long stretch of poor conditions right through the 27th. The wind stays up, the swell stays inconsistent, and the energy drops off significantly, sometimes dipping below 100. It's a long, drawn-out period of frustration. The good news is that Alnes Lighthouse is a point break, and it's fairly exposed to the northwest. That means when the wind does finally lighten up, it should handle the swell a bit better than a beach break would. The water temp is about average for this time of year, so no surprises there.
The second week is leaner. The pulse of swell we saw early in the week is gone. We're looking at smaller, weaker swells through the end of August, mostly in the 1ft to 3ft range with the energy truly bottoming out. The wind remains a problem for the most part. There’s one last gasp on the 28th where a longer period swell (11 seconds) shows up, but it’s got a 19 mph cross-shore wind ruining the party. It looks more interesting for the kitesurfers than for us.
So, there you have it. It’s going to be a lot of staring at the ocean, but for the dedicated few, the morning of Monday the 17th is the window. The next week is for waiting and watching the forecasts, because it tends not to stay this poor for long.
Rusty out.

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.
