The Lowdown
Alright, let’s talk Harlyn. I’m not gonna sugarcoat it – the next couple weeks are pretty quiet, but there are a few moments where you’ll want to be in the water. The water temp is 65°F, which is over 4°F warmer than usual, so you’re good in a spring suit.
First real chance is this Sunday, September 13th. Morning has 5ft waves out of the west, with a 10-second period and moderate energy (450). The wind is cross, so it’s a little bumpy, but it’s the best we’ve seen. The afternoon cleans up with a light cross-off and 4ft waves – still ordinary, but rideable.
Then we hit a dead zone. From Monday the 14th through Friday the 18th, it’s just small and messy. Not worth paddling out.
Saturday the 19th morning gives us a clean offshore wind from the south and 3ft waves from the west. It’s small, but it’ll be glassy – great for a longboard if you just want to cruise. Energy is weak (151), but the conditions are nice.
Now, Wednesday the 16th – this one is for the brave. Swell jumps to 10ft from the WNW, with massive energy (1476 in the morning, 1121 in the afternoon). That’s a lot of water. But the wind is blowing 25 mph onshore, so it’s going to be a mess. Period is only 8 seconds, so it’s a short, lumpy wind swell. Only experts should even think about it, and honestly, it might be better for kite surfers.
Into the final week, Sunday the 20th afternoon has a 7ft west swell, 9-second period, and clean cross-off wind. Energy is 749 – that’s solid. Tuesday the 22nd and Wednesday the 23rd offer the most consistent surf, with 4ft to 4ft west swells and clean cross-off winds. Wednesday the 23rd morning has a 4ft west swell, 11-second period, and a light breeze – that could be the quiet standout of the whole run.
So, bottom line: Sunday the 13th is your early pick, Saturday the 19th for the glassy small stuff, and the last few days from the 22nd to the 24th look the most consistent and clean. Not a classic forecast, but there’s enough to keep you going.

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.
