The Lowdown
Right then, let's have a look at what's on offer for the Harlyn area. Straight up, it's a quiet start. The first solid week-and-a-bit is a proper struggle, with tiny, messy leftovers and no real drive. The water's sitting at a warm 65°F, which is a touch warmer than you'd expect for this time of year, but you won't be caring about that when you're staring at flat, blown-out lines.
The first real glimmer of hope doesn't show up until Saturday the 5th of September. Even then, it's a marginal call. Expect a 6ft swell from the west with a moderate cross-offshore breeze, but it's all looking a bit average and rain is threatening. The energy is moderate at 435 (combined energy). Not something to get excited about just yet.
The standout, and the only one worth calling a proper session, is shaping up for Monday the 8th of September. This is a big, powerful groundswell. We're looking at a solid 12ft swell from the west, with a very long period of 16 seconds. That's a lot of water moving. The combined energy is a massive 6719, which is strong. There's a fresh offshore breeze from the south, so the face should be clean. Now, a word of warning: this is a serious one. At over 8ft, it's for experts only. The long period means it'll be walling up and looking for a decent bank, but Harlyn is a sheltered, inconsistent spot so it might not handle the power perfectly. Still, for the brave, it's the best option by a long shot. The wind does swing cross-offshore in the afternoon, and the swell drops to 10ft with a 15-second period, still a very heavy wave.
The day after, Tuesday the 9th, the ocean is still rumbling with an 12ft morning swell and a 16-second period, but the wind is gusty and the quality will be down. It's a close-out zone for most.
So, the first week is a write-off, but that Monday the 8th is a proper, serious session. Get on it if you've got the skills and the bottle. The rest of the window is a mix of messy, wind-affected slop and smaller, cleaner but weak days. You'll have to be patient.

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.
