The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the cards for Harlyn over the next couple of weeks.
Honestly, the outlook is a pretty bleak one for the first week and a half. We're looking at a long stretch of poor surf conditions, with nothing really worth paddling out for from Thursday the 6th right through to around Thursday the 13th. That's a solid eight days of flat, choppy, or just plain messy conditions. The swell is tiny, mostly around 1.0ft to 3ft, and the wind is nearly always onshore or cross-onshore, just making a mess of things. The water temp is sitting at 66°, which is a touch warmer than usual for this time of year, but that's about the only comfort.
Friday the 14th of August finally offers a slight glimmer. The morning session at Harlyn sees a clean 3ft swell from the west-northwest, with a light cross-offshore breeze. The combined energy is weak (127), but it’s the first time things look clean. It's not a standout, just a 'yeah, I could get a wet one in' kind of day.
The real story, and the only time this forecast gets interesting, is around the 19th and 20th of August. We've got a solid pulse of swell arriving. The morning of Wednesday the 19th sees a chunky 8ft west-northwest swell hitting, with a combined energy of 671, and it's clean with a cross-offshore wind. That's a big, powerful swell. Now, at 8ft, this is getting into expert territory, especially for a beach break. This swell is short period (8 seconds), so it'll be a bit fat and dumpy, not a classic long-period groundswell. The next day, Thursday the 20th, is also a notable one. The swell is still a solid 8ft from the west, with energy at 706, and the wind is light and cross-shore. The conditions on the morning of the 20th look like the best of the whole run – light cross-shore winds and a bit of shape. This is the standout. For a surfer who knows what they’re doing, that Thursday morning could be the one to circle. It's a big, powerful, and chunky swell, so it's not for the faint of heart, but if you’ve got the skills, it’s the best on offer.
The rest of the run after that drops off again, with onshore winds returning on the 21st. So, to sum it up: a long, dry spell, then a promising but expert-level window around the 19th and 20th, with Thursday the 20th morning being the clear winner.
Rusty out.

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.
