The Lowdown
Right then, I’ve had a good look at the charts for the next couple of weeks and, well, to be honest, it’s a bit of a tough one for Harlyn. The forecast is a real mixed bag and there’s not a whole lot of quality riding to get excited about. There’s a run of poor surf stretching right through the first week and into the second, with the wind and swell just not lining up. The water temperature is about average for the time of year, so nothing to worry about on that front.
The first real chance to get wet doesn’t come until Sunday, the 23rd of August. Even then, it’s only just a sniff of a wave. We’re looking at a small 2ft swell from the west, with a period of 9 seconds. The combined energy is weak (124). The big plus here is clean conditions with an offshore wind from the SSE, so the surface will be glassy. It’s not going to be a classic, but if you’re desperate for a paddle, it’s the best on offer.
The following Monday morning, the 24th, is a similar story. Another small 2ft west swell, with a light cross-offshore breeze from the WSW. It’ll be clean again, but the wave energy is very weak (101). It’s surfable, but just. You’ll be working hard for not much reward.
Now, looking further ahead, there’s a bit more energy showing up, but with a big caveat. Towards the end of the month, the 27th and 28th of August, the swell picks up to a head-high 5ft to 6ft from the WSW. The combined energy jumps into the moderate range (316 to 528). The winds are forecast to be fresh and cross-offshore, which is great for clean faces. However, the swell period is only around 8 seconds, which is short-period wind swell, so the waves will lack that real punch and shape. It’s a promising but less certain call being that far out. It might be worth a look, but don’t book the day off work just yet.
Other than those few windows, the rest of the 16-day forecast is a write-off. There are days with strong onshore winds, and a big jump in swell on the 19th of August hits 8ft to 10ft, but with a howling onshore wind, it’s just a total mess. For a beginner spot like Harlyn, that’s a no-go. The break is sheltered and inconsistent at the best of times, so this blank run isn’t a huge surprise.

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.
