The Lowdown
Hey crew, Rusty here. Look, I’ll be straight with you—this 16-day stretch for Curly is a real mixed bag. We’ve got some proper size coming through mid-week, but the wind gods aren’t playing nice for most of it. Don’t expect much action this weekend; it’s looking pretty ordinary.
The water temp is sitting at about 63°F, which is pretty much what you’d expect for this time of year (anomaly of -1°F). Nothing to write home about.
Let’s start with what’s on offer. Monday the 14th morning is your first real chance to get wet. Swell is a tiny 2ft from the south, period around 11 seconds—clean lines with a light cross-offshore breeze from the north. The energy’s weak though, only about 196 (combined energy). It’s small and clean, but you’ll be fighting for scraps. Expect crowds here.
Now, things get interesting mid-week. Wednesday the 16th sees a big jump in size—by the afternoon we’re looking at a solid 13ft south swell, period 10 seconds. That’s a lot of water moving, with combined energy hitting 2938. But here’s the rub: the wind is a fresh cross-shore, making it messy and lumpy. This is expert-only territory; if you’re not solid, stay on the sand. Thursday the 17th morning drops slightly to 10ft from the south, period 9 seconds, energy 1334, but the wind is still moderate cross-shore. The report says it might even be too big for this break by then.
Your standout window? It’s gotta be Friday the 18th morning. Swell drops to a manageable 4ft from the south, period 8 seconds, combined energy 292. But the wind swings light offshore from the north-northwest, nearly glassy, giving us clean conditions. That’s the one to aim for this week. Not huge, but clean and workable.
After that, we get a brief window on Saturday the 19th morning when a small 3ft ESE swell (period 11 seconds) meets a light offshore from the west. Energy is moderate at 386, and it’s clean. Worth a look if you’re keen.
The rest of the run up to the 27th is pretty grim—mostly small, choppy, and onshore. There’s a faint hope on Friday the 25th morning with a 4ft NE swell, period 6 seconds, and clean light offshore winds, but it’s short-period windswell and not much push. Saturday the 26th morning is flat calm and glassy, but the swell is only 3ft from the northeast with weak energy (109).
Overall, don’t hold your breath for epic waves. The best of it is Friday the 18th morning and maybe that Saturday the 19th morning. For the brave and skilled, Wednesday/Thursday has size but it’s ugly. Keep your expectations low and your eyes on the forecast.
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.
