The Lowdown
Alright, Rusty here. Let's have a look at what's cookin' for the next couple of weeks at Lagide.
Right off the bat, I gotta be honest with you: it's a bit of a slow start. We’ve got nothing happening this Sunday the 16th—that wind is straight on it and the energy is all wrong. The first real glimmer of hope comes Monday morning, August 17th. The swell is a clean 6ft from the NNW at 8 seconds. While the period is a touch short, the wind is glassy, light from the ENE. That's the kind of morning you wake up early for. Water temp is sitting at 67°, which is about a degree and a half cooler than usual for this time of year, so you'll want a decent spring suit.
Tuesday the 18th morning isn't bad either, with a little 5ft NNW swell and a light offshore from the SSW. It'll be clean, but the energy is only moderate (302). The rest of that week into the weekend gets messy with onshore winds and choppy conditions. There's some moderate wave energy mid-week (427 on Thursday afternoon, 681 on Friday morning), but that fresh breeze from the NNW is ruining it all.
The weekend of the 22nd and 23rd is pretty much a write-off. We get some cross-off winds and clean lines on Saturday afternoon, but the swell is weak at 4ft and only moderate energy (354). Sunday sees the wind picking up again.
Looking further ahead, the period from the 24th to the 29th is sadly a total bust. We've got a solid week of onshore winds and very weak, short-period windswell. The wave energy drops below 200 for several days, and the wind states are all "on" or "cross-on." Not worth paddling out.
Now, here’s where it gets interesting. The last day of the month, Monday the 31st of August, is shaping up as the real standout. It's still a bit far out to lock in, but the potential is there. We’ve got a nice 5-6ft NNW swell rolling in, but the key is the energy—strong at 414-494. The wind turns cross-off from the WSW in the afternoon and the surf will clean right up. With that kind of energy and a decent size, Lagide could have some proper, powerful waves. This is the one to circle on your calendar.
So, for the best bet: Monday morning the 17th for some glassy, clean 6ft waves, and keep an eye on Monday the 31st of August for a bigger, more powerful session.
Rusty.

Information about the Lagide Surf forecast
The above surf forecast table for Lagide provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Lagide can be found by selecting the local surf guide option on the grey menu. Our Lagide 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 (Lagide) 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 Lagide 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.
