The Lowdown
Alright, let’s break it down in feet and miles per hour.
Over the next couple of weeks here at Harlyn, it’s a real quiet stretch. Water’s at about 63°F – pretty normal for July.
Friday the 25th and Saturday the 26th of July? Forget it. Pushing 19 mph cross-shore wind, lumpy, poor shape. Sunday the 26th gets a bit of size – 7ft from the WNW, but the combined energy is moderate (469) and the wind is cross-onshore at 22 mph, so it's a messy, blown-out mess.
Monday the 27th is a little smaller – 4ft – but it’s still choppy. The first real window comes Tuesday morning the 28th of July: glassy, clean, with a 3ft WNW swell and a bit of energy (108). It’s tiny but it’s the smoothest, most rideable we’re going to see all week. You could get a few little ones.
From Wednesday the 29th through Friday the 31st, it’s mostly knee-high or smaller with cross-on breezes – a real dry spell.
Then Saturday the 1st of August is our standout: a clean 4ft swell with a light offshore wind in the morning, energy around 129. Get out early – by afternoon it picks up to a fresh 19 mph breeze and blows it out.
After that, we drop back into weak, choppy conditions with not much power until Sunday the 9th of August, when we see a bigger 6–7ft WNW pulse (energy up to 383). Looks promising on the chart, but the wind is cross-onshore again at 16 mph – so it’s rough and lumpy, not clean.
Bottom line: the only real clean session is that Saturday the 1st of August morning. The rest is either blown out or too small. Harlyn’s a beginner-friendly spot, but this stretch doesn’t do it many favors.

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.
