The Lowdown
Alright, let’s have a look at the 16-day window for Harlyn. To be straight with you, it’s a pretty bleak run of days. This spot is a beginner-friendly, sheltered bay, but it’s inconsistent and often struggles with the wrong wind. For the next week and a half, the conditions just aren’t coming together.
The first surf of any real note doesn’t show until Tuesday the 18th of August. That morning, we’re looking at a clean, light breeze with a 3ft swell out of the west at 8 seconds. The combined wave energy is moderate at best (145). It’s surfable, but very ordinary. That’s as good as it gets for a while.
After that, the pattern goes back to mush. Wednesday the 19th and Thursday the 20th are onshore and choppy, with the same 3ft west swell, but the wind is just messy. By Friday the 21st, things clean up a little in the afternoon – light breeze, cross-offshore wind, with a 2ft west swell at 10 seconds. Barely worth the paddle, but it’s the most promising of the entire stretch.
There’s a long gap after that. Saturday the 22nd offers a weird moment of glassy conditions in the afternoon with a tiny 2ft west swell – but it’s still considered poor surf. The last week of the window is essentially a write-off. The swell tries to push 5ft on the 24th and 25th, but it’s coming from the wrong direction or the wind is junk.
Truth is, Harlyn just isn’t firing. If you’re desperate, Tuesday the 18th morning or Friday the 21st afternoon are your only real windows, and they’re not exactly setting the world on fire. The water temp is about average for this time of year, so no surprises there. This is just one of those stretches where the forecasts can change, but right now it’s a waiting game.

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.
