The Lowdown
Alright folks, Rusty here. Let’s take a look at what’s cookin’ for the Alnes Lighthouse stretch over the next couple weeks. Gotta be honest with you, this forecast is a bit of a tough one to read. For the first week and a half, it’s mostly a write-off. We’re dealing with a lot of chop, cross-shore winds, and just plain messy conditions. The water temp is sitting at 56°, which is about 1° cooler than normal for this time of year, so nothin’ wild there, just a bit brisk.
The first real light at the end of the tunnel shows up on the Saturday morning of the 8th of August. We see a bit of a pulse with a 4ft swell from the southwest, period of 7 seconds, and a cross-offshore wind from the south at 9 mph. The combined energy is moderate (225), but the wave comment tells us it’s still poor surf conditions. The afternoon gets a bit bigger, 6ft from the WSW, still cross-off but the wind picks up to 12 mph. The energy jumps to 444, but it’s still only a marginal call. Sunday the 9th is a total write-off with strong winds and a big, messy 10ft swell that’s only for the experts, and even then, the wind is a nightmare.
The following week doesn’t offer much more. The morning of Wednesday the 12th has a 3ft swell from the NW with a 7-second period, but it’s cross-on. The afternoon cleans up a bit with an offshore breeze from the ESE at 6 mph, giving us 3ft. It’s surfable, but very ordinary.
Then we get to the real standout. The Thursday the 20th of August. This is the one to circle on the calendar. Both morning and afternoon sessions are looking like the best we’re gonna get. Morning has a glassy 4ft swell from the west, period of 10 seconds, with a light south wind at 3 mph. The energy is a solid 355. The afternoon is clean too, with an offshore wind from the ENE at 6 mph, delivering 4ft from the west. The forecast says “expect good surf conditions” for both sessions. This is where it’s at. The long 10-second period means the waves will have some proper shape and energy, and with glassy or offshore winds, Alnes Lighthouse will be clean. Just a heads up, this spot can get crowded sometimes, so get there early if you can.
The 20th is the goldilocks day. For the rest of the run, it’s a whole lot of “poor surf conditions” and “ordinary” waves. The 19th of August has a glassy 4ft and 4ft swells, but the energy is only around 200, so it’s nothing special.
So, overall, hold out for Thursday the 20th. That’s your window. The rest of the 16 days is mostly a waiting game with a lot of onshore junk. Keep your eye on that date.
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.
