The Lowdown
Alright folks, Rusty here. Let’s be honest with each other right from the start: this is a tough stretch for Harlyn. For almost two weeks, the surf is going to be pretty disappointing. The wind is mostly onshore or cross-on, and the swell is tiny and weak. There’s a long gap of poor conditions, but we do get a little flicker of hope at the very end of the outlook.
The first real chance of anything rideable isn't until Saturday, August 1st. Up until then, it’s a real grind. The swell is small, often under 3 ft, with short periods and very weak energy. The wind is almost always blowing straight onshore, making it a mess. That’s a solid 13-day stretch of barely any surf on offer.
Now, the standout. It’s not going to be epic, but it’s the only window that looks even close to fun. Saturday, August 1st morning is the one to watch. The wind goes totally glassy, which is a massive positive. The water temperature is a touch warmer than normal for the time of year, sitting at 64°. The swell will be from the WNW at 2 ft with a period of 10 seconds. The combined energy of all swells here is moderate for this spot at 101. It’s not going to be big, but glassy conditions will make it clean and rideable. The wind is calm, so it’ll be a nice morning to be out. Keep in mind, Harlyn is a sheltered, inconsistent beginner spot, and with the WNW swell direction, it might just line up okay. The rest of that day and the days after, the wind goes back onshore, killing the quality.
So, bottom line: the first couple of weeks are a write-off. The only real chance to get wet is that glassy morning on the 1st of August. The rest of the time, the onshore wind and weak swell mean it’s a better time to work on your tan than your cutback.
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.
