The Lowdown
Alright folks, Rusty here. Let's have a look at what Glenfield is cookin' up for us.
Well, the first thing to say is we've got a bit of a wait. The first few days are a write-off with strong winds and messy conditions. The surf really doesn't get going until Sunday the 9th, but even then, it's a bit of a tricky one. The wait is worth it though, because there are some proper, powerful swells heading our way.
The main event, and the standout, is shaping up for the morning of Sunday the 16th of August. The water is about average for this time of year. It's going to be an absolute glass-off with zero wind. The swell is a solid 7ft, coming from the WSW with a period of 14 seconds. That's a proper groundswell, and it'll be clean. It's a bit big for beginners, but for the experienced crew, it's going to be a treat. The combined wave energy is strong at 1643.
The other one to circle on your calendar is the morning of Monday the 17th of August. We're looking at a clean 8ft swell from the WSW with a 16-second period, and a light offshore breeze from the ENE (3139). Again, this is for the experienced surfers, as anything over 8ft starts to get real serious. The energy is strong.
Before that, we have a bit of a mixed bag. The swells that arrive on the 9th and 11th of August are just too big for this break, with heights between 12ft and 16ft and massive wave energy. On the morning of Thursday the 13th of August, we get a clean window with an 8ft SW swell and a moderate offshore breeze from the E (2650). That's a solid option, but the wind is a bit stronger than the real standouts. The morning of Wednesday the 19th of August also looks promising with a glassy 10ft WSW swell and very long 17-second period (5663), but that's a long way out and the forecast might shift.
Towards the end of the run, the swell starts to back off. The morning of Friday the 21st of August has a clean 6ft SW swell with a light offshore breeze, which is a nice, more manageable size for a wider range of surfers.
So, bottom line: the 16th and 17th are the ones to lock in if you're an experienced surfer looking for clean, powerful waves. The rest of the time is a mix of too big, too windy, or just average. Keep your eyes on that long-range glass-off on the 19th, too.
Rusty.

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