Table - best surf conditions forecast for Avalon-North over the next 16 days.
Alright, let’s get into it. This is Rusty, and I’m looking at what’s on the cards for Avalon-North over the next couple of weeks. Honestly, it’s a tough stretch, so I’m going to be straight with you.
Right out of the gate, things are a bit messy. Wednesday morning the 8th of July has a solid 8ft of swell from the SE, but the wind is cross and there’s a bit of rain in the air. It’s powerful – the combined swell energy is 1770 – but it’s not clean. It’s more of a wrestle than a glide. The water temp is sitting at 66°, which is bang on average for this time of year, so nothing unusual there. That afternoon stays lumpy with the wind picking up.
We get a little window of hope on Thursday morning the 9th. The swell drops to a more manageable 6ft from the SE, with a light cross-offshore breeze (SSW at 9 mph). It’s clean. That’s the standout of the whole run. The energy is still chunky at 881, but with that glassy surface, it could be really fun for anyone who knows their way around a point break. The swell period is 10 seconds, so it’ll have a bit of push.
From there, it’s a slow fade. Friday the 10th still has some 5ft to 5ft waves, but the wind starts shifting around, and the quality drops. By Saturday the 11th, we’re down to 4ft and clean in the morning, but it’s weak. Sunday the 12th through to the middle of the following week? Forget about it. For about five days straight, from the 12th to the 16th of July, there’s basically nothing worth paddling out for. The swell energy drops to near zero, and you’d be staring at flat lines.
There’s a tiny flicker of life much later – around the 19th of July, a long-period 12-second SE groundswell sneaks in, but only at 1ft. It’s too small to get excited about. Then again on the 21st of July, there’s a 3ft SSE swell with some energy back up to 108, but the period is short at 7 seconds, and the wind is offshore, so it’s clean but barely surfable.
The best bet is Thursday morning, the 9th of July, at Avalon-North. It’s a consistent advanced point break, and with that clean, cross-offshore wind and a solid 6ft from the SE, it’s the only real window of quality. Don’t expect much else to work between now and then.
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.
