The Lowdown
Alright folks, Rusty here. Let's have a look at what's shaping up for Alnes Lighthouse. It's a point break, and the swell window is fairly exposed, looking for something out of the northwest. The water's sitting at about 55°F, which is a touch cooler than average for this time of year, nothing too crazy.
Right now, we're in a bit of a flat spell. The first real surfable window doesn't show up until the afternoon of Monday the 31st of August. The days before that are all tiny, messy, or just not worth getting wet for. So you're looking at a solid gap of almost a week with nothing on offer.
Monday the 31st of August finally brings some life. The afternoon looks the best, with a clean 5ft swell from the northwest, period around 8 seconds. The wind goes glassy, and the wave energy is moderate at 334. This is the standout of the early window. The morning has a bit more size at 6ft but with a cross-onshore wind, so the afternoon is the call for a clean session.
Tuesday the 1st of September gets messy again with a moderate cross-onshore breeze and a dropping swell. Not your day.
Wednesday the 2nd of September sees a new pulse of energy, with the swell period stretching out to 11 seconds. The morning offers 4ft from the NNW, but the wind is a light cross-shore, leaving a bit of a ripple on the face. The combined energy is moderate (452). It's a "maybe" session, not a standout.
Things start getting interesting around Friday the 4th of September. The morning has a solid 12ft swell from the WSW, with moderate energy (2275) and a 10-second period. But the wind is a cross-shore, creating some chop. That's a big, lumpy day. This size is for experts only – over 8ft is no place for beginners. The afternoon stays big at 12ft but the wind picks up and swings onshore, making it a write-off.
The real standout of the whole outlook is Monday the 7th of September. The afternoon session is looking prime. We've got a clean 5ft swell from the northwest with a 9-second period, and the wind is offshore from the southeast, 9 mph. The combined energy is a solid 715. This is the one to circle on the calendar. It's a week and a half out, so keep an eye on it, but the signs are promising for some good, clean lines at the point.
After that, Tuesday the 8th drops back down to a smaller, glassy 3ft, and the rest of the run looks like it gets blown out or fades away.
So, to sum it up: the first week is a write-off. The standout is the afternoon of Monday the 7th of September for clean offshore conditions. The backup is the glassy afternoon on Monday the 31st of August. If you're an expert, the big 12ft swell on the morning of Friday the 4th might be worth a look, but the wind isn't perfect.
Stay stoked, and I'll catch you in the water.

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.
