The Lowdown

Alright, let's talk about the forecast, and I'll be honest with you, it's going to be a tale of two extremes. We've got a big, unruly swell hitting early, a flat, useless middle, and then one beautiful, clean window at the very end. So, pick your moments.

The first couple of days are all about that powerful south swell. Thursday morning the 17th is the biggest, with solid 10ft faces, but it’s forecast to be too much for this spot. The wind will be blowing a moderate cross-shore, messing up what could be a clean face. The water is moving with a ton of energy, but it’s going to be a battle, not a pleasure. It's a bit of a groaner. The rest of that week stays on the messy side with onshore winds making things lumpy and sectiony, even as the swell starts to back off.

The weekend and the following week are pretty much a write-off for wave size. The swell drops right out, and we're looking at tiny, knee-high slop. There are moments of clean conditions, like Saturday morning with a light offshore breeze, but there’s just not enough water to make it interesting. The energy in the water is super weak, and all the juice has gone out of it. You’ll be doing more floating than surfing.

There's a slight pickup around the 23rd and 24th, but it's a short-period windswell from the east. That stuff is hopeless for a beach break, with a period down around 6 seconds. It’s just wind chop and bump. The cross-shore winds will have it all chunky and closed out. Honestly, with that combo of windswell and breeze, you'd be better off rigging up a kite than grabbing your shortboard.

From the 25th right through to the 29th, we’re back to small, weak waves. The period stays super short, and the energy stays low. It’s the kind of surf that breaks soft and fat, with onshore winds keeping it lumpy. There are a few glassy mornings, but even then, there's just no power behind the swell. We’re in a proper flat spell.

But, and this is a big but, the forecast shows a gem hidden at the end. The standout session is the morning of Thursday, October 1st. That's when a clean, 6ft south groundswell with a proper 11-second period rolls in. And the wind? Glassy. Absolutely dead calm. The energy reading is strong, and with that offshore condition, Curly is going to be breaking with real shape and power. The water temp is around 64°, which is normal for this time of year, so you’ll be fine in a good wetsuit.

So, there you have it. A lot of waiting around, but one truly special morning to look forward to. Circle the 1st of October on the calendar. That’s the one you don't want to miss. Everything else is just filler. Keep an eye on the forecast, and be ready to move when that clean swell finally shows up.

Information about the Curl Curl Surf forecast

The above surf forecast table for Curl Curl provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Curl Curl can be found by selecting the local surf guide option on the grey menu. Our Curl Curl 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 (Curl Curl) 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 Curl Curl 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.
