The Lowdown
G’day, Rusty here. Let’s get straight to it. The next couple of weeks have a few clean windows, but only one morning truly stands out. The early days are small and average, so don’t rush out expecting magic.
Tuesday morning at Curl Curl (Sydney) starts small – 4ft of SSW swell, but the period is short at 7 seconds. Water temp is 62°, which is about 2° cooler than the usual for this time – you’ll feel that. The cross-off breeze keeps it clean for a beginner-friendly wave, but there’s no power behind it. Energy is weak-to-moderate (201). A lap-sitter, not a standout.
Tuesday afternoon is the real opener. The swell builds to 6ft from the S, the period stretches to 11 seconds, and the wind turns glassy offshore from the NW. Energy jumps to strong (801). This is a proper clean session – the kind where the waves have shape and push. Crowds are likely, but it’s worth the company.
Wednesday morning keeps the momentum – 4ft S swell, 10 seconds, offshore W wind (370). Solid and clean. A good backup. Wednesday afternoon fades – 3ft, wind swings WSW and strengthens. Still rideable, but less special.
Thursday is a mess. Morning has 3ft S swell at 8 seconds, with average shape. Afternoon sees a bump to 7ft S swell with energy spiking to 1064, but the wind turns onshore from the ESE. Close-outs. Leave it.
Friday morning – 4ft S swell, 9 seconds, W cross-off (244). Fun, but not worth canceling plans. Friday afternoon gets blown out with onshore SE wind.
The weekend is a complete washout. S/SE winds at 25 km/h, short-period junky swell (6-7 seconds), and rain moving in. Choppy, cross-onshore slop. Not a chance.
Monday and Tuesday of the next week stay poor – ESE winds onshore, swell dropping and ragged. The beach looks more like a kite zone than a surf zone.
Then, Sunday the 23rd morning. This is the one. Swell hits 6ft from the NE, period at 10 seconds, with a clean offshore SW wind. Energy is massive – 1283. Lined-up, clean, and powerful. This is the pick of the fortnight. Expect the crowd – it’ll be worth it. The water should have warmed up a touch by then, too.
Monday the 24th – swell drops, but the period stretches to 11 seconds, which might make it too straight for this beach break. Tuesday the 25th – a huge 10ft S swell with 2111 energy, but that’s way too big for this spot. Experts only, and even then, risky.
The tail end is fading fast. Wednesday the 26th has a tiny 3ft S swell with weak energy (138), ordinary at best. The main hope is that Sunday the 23rd – it’s a few days out, so call it promising, not guaranteed.
Keep it simple: Tuesday arvo if you can, and lock in Sunday the 23rd as the big one. The rest is filler.
Rusty out.

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.
