The Lowdown
Alright, Rusty here. Let’s break it down in feet and miles.
It’s a tough run to start. Sunday the 13th at Harlyn sees a 5ft west swell, 10-second period, with a moderate 448 combined energy. The wind is a cross-off at 15 mph from the southwest, cleaning things up some, but it’s still marginal. Not worth the drive.
Monday the 14th fades fast. Swell drops to about 4ft from the west, period down to 9 seconds, energy at 195, and the wind stays cross-off at 12 to 15 mph. Poor conditions.
Tuesday the 15th bumps up to 6ft from the west, but the period is short – 8 seconds. Energy hits 442, but the wind is a fresh 22 mph cross-shore from the WNW. Lumpy cross-chop all day. Poor. Wednesday the 16th gets a 6ft west swell with an 11-second period – that’s some proper energy with 883 – but the wind is a fresh 19 mph cross-on from the NNW, making it choppy. Same story through Thursday and Friday: moderate to fresh onshore and cross-shore winds kill any quality.
Finally, the weekend of the 20th and 21st shows a glimmer. Sunday the 20th morning has a light 3 mph breeze from the WNW, a 5ft west swell, 10-second period, with 432 energy. It’s nearly glassy. The afternoon is clean with a 6 mph cross-off from the WSW and a 4ft west swell.
The standout is Monday the 21st morning at Harlyn. A clean 4ft west swell, 9-second period, combined energy at 283, and a light 9 mph offshore wind from the south. That’s glassy, clean, and your best chance for a decent wave this entire outlook.
From the 22nd onward, it all falls apart. Swell drops below 3ft, the period gets short and jumbled, and the wind turns from the north and east. By the 24th, we’re down to 1ft from the WNW, and the 28th shows a measly 2ft with onshore junk. A long flat period after that Monday session.
Bottom line: aim for Monday the 21st morning at Harlyn. That’s your best and only real call. Everything else is a hard pass.

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.
