The Lowdown
Alright, Rusty here, let's get into it.
First up, we’ve got a bit of a flat start. The first real session to look at is Wednesday morning, the 12th of August. Curly’s got some knee-to-waist high swell rollin' in, around 4ft from the south. The period is a solid 10 seconds, so it's got a bit of push. The wind's coming from the west at 9 mph, keeping it clean with a cross-off breeze. The water is sitting at 62°F, which is a bit colder than what we’re used to this time of year. The combined energy is moderate (329). It’s not going to be a world-beater, but for a beginner-friendly spot, you could have a fun little session.
Now, Thursday morning the 13th sees a jump in size to 5ft from the south-southwest, but the period drops right off to a short, choppy 6 seconds. That’s gonna be a messy, crumbly wave. The wind is a moderate 12 mph from the west-southwest. Not the best.
Thursday afternoon is a write-off. The swell jumps to 6ft from the south, but the wind switches onshore from the southeast, and the combined energy jumps to a strong 902. It’s gonna be a washing machine out there. Keep the board on the beach.
Friday morning the 14th is a return to form. Swell drops to 4ft from the south with a 9-second period. The wind is a light 6 mph from the west-southwest, keeping it clean. It’s a small morning, but a good one for a beginner to get a few. The energy is moderate (249).
After that, it gets a bit grim. From Saturday morning through to Monday, we’ve got onshore winds and lumpy, choppy conditions. The swell sticks around the 5ft to 6ft range, but with short periods and cross-onshore wind, it’s not worth paddling out. The best you can say is that the kite surfers might be having a field day.
We get a bit of a reprieve on the 19th of August, Wednesday morning. Glassy conditions with a light 3 mph wind from the south-southwest. The swell is a small 4ft from the east-southeast, but the period is still short at 7 seconds. It’s surfable, but it’s ordinary.
The action picks up properly from the 21st of August. Friday morning sees a 3ft swell from the east-northeast at 8 seconds, with a clean 9 mph offshore wind from the west. The energy is light (141), but it’s clean.
Saturday morning the 22nd is a standout. The wind is a light 6 mph from the west-northwest, blowing offshore. The swell is 3ft from the east-northeast, with a 10-second period. The energy is moderate (200). It’s clean, small, and fun. It’s a good morning for a log.
Sunday the 23rd is another cracker. The morning and afternoon both look solid. The wind is a gentle 9 mph from the west-northwest, offshore. The swell is 4ft from the east-northeast, and the period stretches out to a nice 10 seconds in the morning, building to 11 seconds in the afternoon. The energy is moderate (331). This is the best of the run. Clean, lined-up waves on offer.
Monday the 24th continues the theme. A 3ft swell from the east-northeast at 11 seconds, with a light 6 mph offshore wind from the west. Energy is moderate (274). Glassy morning.
After that, the swell fades and the wind picks up, becoming a bit too strong for the small waves on offer, until we get to the 27th of August. Thursday morning... hold onto your hat. The data is showing a 10ft swell from the south, with a 10-second period and a combined energy of 2280. That’s a massive, powerful swell. The wind is a clean 9 mph from the west-southwest, keeping it clean. But look, I’ve got to be honest, that size is too big for Curly. It’s an expert-only zone, and even then, it’s going to be a heavy, dangerous beast. The model is even saying it’s predicted to be too big for this break. So, we’ll keep an eye on it, but for now, don’t be a hero.
So, the real standout is Sunday the 23rd of August. That’s your best bet. Clean, consistent, east-northeast swell with a nice long period and offshore winds. It’s going to be a classic winter morning. The 22nd and 24th are also very good, but the 23rd is the pick.
Stay safe out there.
Rusty.

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.
Curl Curl is 3 km (2 miles) from Dee Why. If you plan a holiday in Sydney North Coast, look for hotels and other accommodation in Dee Why. Dee Why has rooms for a wide range of budgets as well as car hire and transport links.
