The Lowdown
Alright, Rusty here. Let's have a look at what's shaping up.
To be straight with you, this outlook is a bit of a slow burn. There's a big gap of nothing really worth paddling out for right at the start. From Tuesday afternoon all the way through to the end of Saturday the 19th, it's mostly flat or just messy, onshore junk. You'd be wasting your time.
The first real glimmer of hope shows up on Sunday morning, the 20th. It's not a classic, but we finally see a pulse of ENE swell pushing through 5ft to 6ft, with a period of 10 seconds. The combined swell energy is moderate (512 to 653). The standout here is Monday afternoon, the 20th, at Avalon-North. The wind goes glassy, dead calm, and you've got a clean 5ft of ENE groundswell. That's the kind of session you wait for. The water temp is about 65°, which is pretty normal for this time of year. Because the swell is over 5ft, it's going to be a bit much for beginners.
Tuesday morning, the 21st, is also glassy with a similar 5ft swell, but the energy is a touch weaker (414). Still, a clean point break like Avalon-North with a good swell direction is worth the stretch.
Looking further ahead, there's a promising window on Thursday morning, July 23rd. This is the one to circle on the calendar. The swell jumps to 6ft from the east with a period of 11 seconds, and the combined energy hits a solid 810 – that's strong, powerful surf. The wind is a light cross-offshore from the southwest, so waves will be clean. This is the standout of the whole outlook. It's solid, punchy, and lined up. Just be aware, it's advanced territory at that size, and the period is long enough that it might stand up a bit straight on a beach break – but on a point, it'll be world-class. Crowds are "often" likely here, so get there early.
The weekend after that, from the 25th, gets a bit sloppy again with strong onshore winds and rain. The swell stays around 5ft to 6ft with a long 12-second period, but the wind ruins it.
The last few days, the 28th and 29th, drop off in size to 4ft and 3ft, but the wind goes offshore or cross-offshore. Clean, small waves for the loggers, but nothing to get too excited about.
So, the best of the best? Monday afternoon the 20th for glassy, clean conditions and Thursday morning the 23rd for the biggest, most powerful swell with light offshore winds. That Thursday is the one to chase.
Rusty.

Information about the Avalon-North Surf forecast
The above surf forecast table for Avalon-North provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Avalon-North can be found by selecting the local surf guide option on the grey menu. Our Avalon-North 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 (Avalon-North) 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 Avalon-North 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.
Avalon-North is 14 km (9 miles) from the city of 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.
