The Lowdown
Alright folks, Rusty here. Let’s take a long, hard look at what’s coming our way. We’ve only got one spot on the radar this time, Alnes Lighthouse. It’s a point break that usually likes some NW push. The truth is, the next week and a half is a tough slog of messy, wind-affected conditions. We are looking at a long stretch of poor surf, mostly from Thursday the 13th of August all the way through to the weekend of the 23rd. The wind is just relentless, coming from the wrong directions or too strong, leaving the sea lumpy and chopped up.
Now, the one small sliver of hope, and it’s a long way off, comes right at the tail end of the window. On Monday morning, the 17th of August, we get a brief moment of calm. It’s glassy, with the wind dropping to zero. The swell will be a modest 5ft from the NNW with a moderate energy level (243). But it’s only a morning window; by the afternoon the wind swings onshore and chops it up.
After that, it’s back to a grind of messy, blown-out conditions until we hit the final days of the period. On Thursday the 27th of August, the morning and afternoon both go completely glassy again. The swell is small at 5ft from the NNE, with a period of just 6 seconds. The wave energy is low to moderate (143 and 162). It’s not going to be a classic, and it’s a long period to wait, but if you’re desperate for a clean, small-wave session on a point break, that’s your best bet in the whole 16 days. The water temp is 55°, which is a bit colder than normal for this time of year, so a good wetsuit is a must. Honestly, for the rest of this stretch, the wind is so persistent that it might be more interesting for kite surfing than paddle surfing.
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.
