The Lowdown
Alright, Rusty here, let’s talk about what’s cooking at Harlyn over the next couple of weeks.
To be honest, it’s a pretty quiet picture overall. We’ve got a long stretch of onshore or cross-off winds messing up what little swell there is. The first real chance of anything half-decent isn’t until Monday the 21st, so you’re looking at over a week of pretty poor conditions before that. After that, the energy drops off again quickly.
Right now, the water’s sitting at 64° at Harlyn, which is a touch warmer than normal for this time of year, so at least the rubber won't feel as thick.
For the first week, don't hold your breath. Saturday the 12th starts with a 4ft W swell at 8 seconds and a cross-off wind at 19 mph, but the combined wave energy is weak at 248, and the comment says it all: poor surf. This pattern of messy, onshore junk continues right through until the end of the following week. Winds are mostly moderate to fresh, and even when the swell tries to push up a bit on Sunday the 20th with an 8ft W swell (energy jumping to 834), the wind is still cross-off and fresh at 19 mph, just making a mess of it. That Sunday morning the 20th does show a brief window with offshore wind and a long 14-second period swell, but at only 1ft, it’s not worth the paddle.
Now, the one standout. Circle Monday the 21st of September on your calendar. That morning we get a solid 5ft W swell with a 10-second period, combined energy at 423 – that’s moderate and punchy. But the real beauty is the wind: light SW at 9 mph, cross-off, and the report says “expect good surf conditions.” That’s the cleanest, most promising window in the whole 16-day run. The swell direction is straight out of the west, which is just off the optimum WNW for Harlyn, but with those winds, it’ll be lined up and workable. Crowds are likely here, so get there early.
After that, Tuesday the 22nd sees everything fade back to small and weak, with energy dropping to 102. Not much else to get excited about.
So in short: wait a week, get wet on Monday the 21st, and then expect a real flat spell to follow.
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.
