The Lowdown
Alright folks, let’s break this down. The next few days are pretty dead. From Wednesday all the way through the end of the month, you’re looking at tiny, weak waves – mostly under 3 feet with short, weak periods. The combined wave energy is low to moderate, barely cracking 100+ on a good day. Wednesday morning has glassy wind, but the swell is only 3 feet and not much behind it. Thursday is even smaller. It’s a long, dry spell, so don’t rush out.
On the 30th of August (Sunday), we see a small bump – waves around 4 feet from the north-northwest, but the wind is cross and the period is short at 7 seconds. Energy is moderate (125-135), but it’s not clean. You’ll be dealing with chop.
The 31st of August (Monday) morning gives you a glassy start and the same 4 feet of north swell, 8-second period, energy 188. It’s surfable, but nothing to write home about. The first of September is similar – a glassy window with 3 feet, but the wind turns fresh and cross-shore in the afternoon, ruining any clean lines.
Now, the 4th of September (Friday) afternoon is where it gets real. Swell jumps to 7 feet from the southwest, period 9 seconds, and the combined energy hits 753 (moderate wave energy). And it’s glassy. For intermediate surfers, this is a serious session. Beginners might find 7 feet a bit much, but if you’re comfortable, go for it. The direction is not perfect for Alnes Lighthouse (it prefers NW), but the clean conditions and solid size make this a standout.
The 5th of September (Saturday) you need to be careful – waves are 10 feet from the west-southwest, period 9 seconds, and energy is 1640 (strong wave energy). But the wind is cross-onshore and choppy. That’s expert-only stuff, and the wind will make it ugly. The 6th (Sunday) is even bigger – 12 feet up to 16 feet with periods up to 12 seconds and energy in the thousands. Too big and messy for anyone but the most experienced, and the cross-onshore wind will hammer it.
The real gem is the 7th of September (Monday). The swell drops to a solid 7 feet from the west-northwest with a 10-second period, energy 826. The wind is light and cross-offshore, giving you clean, lined-up waves. This is the best session of the entire 16-day window. The direction is closer to the optimum NW, and the wind will groom the faces nicely.
The 9th of September (Wednesday) morning is also good – dead calm, glassy, with 6 feet from the north-northwest, period 9 seconds, energy 505. Solid, clean, intermediate-friendly surf. The spot, Alnes Lighthouse, is a point break, so expect crowds sometimes.
So to wrap it up: the first week is a bust. Your best bets are the 4th of September (Friday) afternoon and hands-down the 7th of September (Monday). After that, the swell gets too big and messy for most.

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.
