The Lowdown
Alright, mate, Rusty here. Let’s get into it.
We’re looking at a pretty quiet stretch ahead at Curly. The water’s sitting at 62°, which is a bit colder than what we’d usually expect for this time of year, so you might want an extra layer.
Right now, there’s not much happening. We’ve got a few days of small, messy surf with onshore winds, so nothing worth paddling out for until Wednesday the 19th. That morning the wind goes glassy, and we get a tiny 2-foot groundswell out of the ESE with a 10-second period. The energy is weak (170), but it’ll be clean. Thursday the 20th morning has a light cross-off breeze and a 3-foot swell from the NE, but the period is a super short 5 seconds, so it’ll be weak and gutless. Friday the 21st has another glassy morning with a 2-foot ENE swell, but again, it’s small.
We get a real gap of nothing special from Saturday the 22nd through to Tuesday the 25th. The surf stays tiny, though there’s a clean window on Sunday the 23rd morning with a 1-foot S swell and 8-second period, but it’s barely a ripple.
The first real standout comes on Wednesday the 26th morning. The wind goes glassy, and we’ve got a 2-foot S swell with an 11-second period. The energy is moderate (201), and the forecast says good surf conditions. It’s small but clean, so if you’ve got a log, that’s your window.
Then we’ve got a promising long-range call for Friday the 28th morning. A solid 2-foot S groundswell with a long 15-second period and a moderate offshore breeze from the NW. That’s a clean, lined-up setup, and the energy is moderate (248). It’s a week and a half away, so keep an eye on it, but it could be the best of the bunch.
After that, things get bigger but messy. Saturday the 29th and Sunday the 30th see the swell building to 5 feet to 8 feet from the S, but the wind is cross or cross-on and fresh, so it’s lumpy and choppy. That’s more kite-surfing territory than paddle surfing. The energy gets strong (1070) on Sunday the 30th morning, but it’s not clean.
Into the first week of September, Monday the 31st is still big and messy, but Tuesday the 1st of September morning has a 6-foot S swell with a 13-second period and a light cross-on breeze. The energy is very strong (1092), and it gets a marginal but decent score. It’s big, so only for the experienced crew.
Overall, the best bet is Wednesday the 26th morning for a clean, small session, and keep an eye on Friday the 28th morning for a longer-period groundswell with offshore winds.

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.
