The Lowdown
Alright folks, Rusty here. Let's break down what's on the menu for the next couple of weeks.
We're looking at a pretty quiet stretch, to be honest. There's a bit of a pulse of swell early on, but it's mostly small and messy for the vast majority of the forecast. The standout is a definite window of opportunity on Friday the 21st, but outside of that, you'll be chasing scraps.
The water is sitting at 55°F, which is a bit colder than normal for this time of year, so you'll want a good wetsuit and maybe some booties for your first session.
The main event, and really the only true highlight, is Alnes Lighthouse (Point) on Friday morning, the 21st of August. We've got a solid 7ft swell rolling in from the NNW, with a period of 9 seconds. That's pushing a combined wave energy of 605 (moderate to strong), so there’ll be some real push behind it. The wind is a light offshore breeze from the ESE, which is going to groom that point into clean, peelable lines. This is an intermediate break, and with 7ft, it's going to be a bit much for beginners, but for anyone with some experience, this is the call. The afternoon shifts to a cross-shore, so the window is the morning.
After that Friday peak, things drop off quickly. Saturday the 22nd sees smaller, weaker swell and a messy cross-shore wind. By Sunday the 23rd, we're down to knee-high mush with onshore winds.
The following week is lean. There's a tiny glimmer of hope on Tuesday afternoon, the 25th of August, when a 4ft W swell (10-second period) meets glassy conditions. The energy is still low (333), but those clean, glassy faces could be fun on a longboard or a fish. It's a marginal option, but the best of the second week.
From there, it's a long, slow fade into September. The swells are small, the winds are mostly onshore or cross-shore, and the energy is weak. There's a glassy day on the 1st of September, but with only 2ft on offer, it's barely a ripple.
So, to sum it up: go hard on Friday morning the 21st if you can. The rest of the time is a waiting game with very slim pickings. This is a classic case of a region that can go quiet, and this is one of those quiet runs.
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.
