The Lowdown
Alright, grab a coffee and listen up. Rusty here.
First up, I’ve got to be straight with you – the next ten days or so for Harlyn are looking pretty grim. This is a real quiet patch, and for a spot that’s already inconsistent, this is a long stretch of nothing to get excited about. We’re talking a solid week and a half of poor surf conditions, with only a tiny flicker of hope right at the end of the month.
Starting Monday morning, 20 July, we’ve got a tiny 2ft swell from the north with a weak 5-second period – that’s barely a ripple. The water is a touch warmer than normal at 64°, but that’s about the only nice thing I can say. The week stays flat and messy, with wind swinging around and keeping things choppy. By the weekend, 25 and 26 July, we get a bump in size, but it’s all cross-onshore wind and lumpy conditions. Not worth paddling out for.
The only real glimmer comes on Wednesday morning, 29 July. We get a bit of a clean-up with a light cross-offshore breeze from the WSW, and a 3ft swell from the WNW with a 6-second period. The combined energy is moderate (111) so it’s got a little push, and the conditions are described as clean. It’s surfable, but very ordinary. If you’re desperate, you might get a couple of knee-high ones.
Then, on Friday the 31st of July, the swell jumps up to 8ft from the west with a period of 8 seconds – that’s strong energy (1038). But hold on, that’s a big powerful wave for a sheltered spot, and with a cross-on wind, it’s going to be a mess. That’s expert-only territory, and even then, it’s marginal. The following Monday, 3 August, and Tuesday, 4 August, show some more size (up to 6ft) with cleaner winds, but the quality is still poor. It’s not the kind of swell you tell your mates about.
So, the honest truth? There’s no standout, no day to circle on the calendar. Harlyn is a sheltered, inconsistent beginner’s wave, and this forecast shows exactly why. Stick to the skatepark for now.
Rusty.

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.
