The Lowdown
Alright folks, Rusty here. Let's be straight with you: it's looking pretty grim on the surf front for the next couple of weeks. We're staring down a long, frustrating stretch of onshores and junky swell. There's a whole lot of nothing on the horizon before we get any real hope, so if you're Jonesing for a wave, you might want to find another hobby for a while.
The next week is basically a write-off. We've got a big gap with no real surf on offer. The energy is weak and all over the place, and the wind just won't cooperate. There's some swell pushing through, but it's mostly cross-onshore and lumpy, making a mess of things. We're talking moderate to fresh breezes chopping up what little push there is.
The first day we might see anything worth paddling out for is Sunday the 13th. Even then, it's nothing to get excited about. Cleaner conditions, sure, but it's a weak 5ft on a long 9-second period, and the energy is only moderate at 320. It's surfable, but very ordinary. You'd be going through the motions just to get wet.
We finally get a real standout, but it's a long way off. Mark your calendars for Friday the 18th of September. This is the one. Overnight, the wind swings offshore and drops right out. Friday morning we've got clean 5ft of west-northwest swell at 11 seconds, with that energy jumping up to 525. But it's the afternoon that has me frothing. The wind goes completely glassy, dead calm, and the waves will be picture-perfect. The swell drops slightly to 4ft, but the period stays at 11 seconds, and the energy is still solid at 405. This is the best call of the whole period. This is the kind of day you ring in sick for.
After that little teaser, the swell fades again and we drift back into ordinary, small surf with cross-off breezes, which is fine for a splash around but not for any real rides. Then, right at the end of the forecast, the 21st and 22nd get properly blown out by a near-gale. The swell will be there, but it's not for paddling. If that wind holds, you might wanna dig out the kite instead of the longboard.
Water temps are about average for this time of year, so a 3/2 wetsuit should do you fine.
The long-range Friday call is promising, but it's a week and a half away, so don't hold your breath just yet. For now, keep the board in the car and wait for that glassy window.
Stay salty,
Rusty

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