The Lowdown
Alright folks, Rusty here. Let's dial into the only game in town for this stretch: Alnes Lighthouse.
Alright, surfers, let's be straight with you. The next couple of weeks are looking pretty grim for a paddle out at Alnes Lighthouse. The groundswell energy is weak (combined energy values sitting around 82-127 for the first week) and the wind is mostly cross or cross-onshore, kicking up chop. The water is currently sitting at 56°F, which is about normal for this time of year.
We're looking at a long, empty run here. After the initial poor conditions, things actually pick up in size around the 9th of August with some proper energy hitting the coast – we're talking combined energy of 479 on the Sunday morning and pushing up to 659 that afternoon, with swell heights around 6ft to 7ft from the WSW. But don't get excited. The wind is screaming from the SW at 28 mph to 31 mph, making it a messy cross-shore mess. That's more of a kite-surfing scenario than a clean paddle session. The conditions stay rough and choppy through the 10th and 11th, even with the bigger groundswell (energy hitting 821 on the Monday afternoon from the NW).
We do get a little window on the 12th of August. The wind eases to a light breeze from the NE and the swell drops to a more manageable 4ft from the NNW. The combined energy is 188, which is still weak, but it's clean and light. It's surfable, but very ordinary. A similar moment pops up on the 18th of August, when a glassy morning with a 1ft swell from the WNW and a period of 12 seconds gives some clean, albeit tiny, lines. The energy is low at 104, so you're scratching for anything.
Honestly, the best chance you've got in this 16-day window is that Tuesday morning on the 12th of August. It's not a standout by any means, but it's the only time the wind lines up cleanly with any kind of size. Even then, don't expect much. The rest is a waiting game.
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.
