The Lowdown
Alright folks, Rusty here. Let’s look at the forecast for Alnes Lighthouse, and honestly, it’s a bit of a mixed bag for the next couple of weeks. The water temp is about average for this time of year, so nothing wild there.
The next week or so looks pretty lackluster. We’ve got small waves and a lot of cross-shore or onshore winds messing things up. There’s a small window on Thursday morning the 13th where the swell picks up a touch to 3.3ft from the WSW with a period of 8 seconds, but it’s still a bit cross and lumpy. Overall, the energy is moderate at best (291), and it’s not going to be anything to write home about. Not worth getting too excited about.
We've got a run of poor conditions right through the weekend and into the start of next week. Expect a lot of chop and wind, with sizes dropping below 3ft. A lot of these days are write-offs for a surf. We're looking at a solid stretch of a few days with nothing going on.
Now, let’s talk about the good stuff. Hold on tight, because Thursday the 20th is the standout. The swell jumps to 5.6ft from the west with a solid 11-second period. The combined energy is strong, hitting 682, and critically, the wind is forecast to be glassy in the morning. This is going to be clean, lined-up, and proper. The water temp anomaly is a wash, but this is the day to be out there. It’s pushing the size a little, but for an intermediate, it’s a great one.
The week after is more of a waiting game. There’s a cleaner window on Friday morning the 21st with 4.3ft from the west and a cross-off breeze, but it's a step down from Thursday. After that, it fades out again, with the swell dropping and the wind turning onshore for the final stretch. The last few days of August look like a flat, choppy mess.
So, to sum it up: the next week is mostly a bust, but keep your eyes on Thursday the 20th. That’s the one. Get out there if you can; it’s going to be the best of the lot for sure.

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.
