The Lowdown
Alright, Rusty here again. Let’s break down the same outlook, but in feet and miles for you.
Truth is, it’s a pretty quiet stretch for Avalon-North over the next couple of weeks. We’ve got a bit of a dry spell before anything really rideable shows up.
The first hint of surf comes Saturday afternoon, August 1st, with a 5-foot SSE swell, but the wind is onshore and it’s looking marginal at best. Not worth paddling out for. Sunday the 2nd has a bit more size, but the wind is messy, kicking up chop.
Monday morning, August 3rd, things start to look a little better. The swell drops to 3 feet from the SE, with an 11-second period. The combined energy is weak (265). The wind is a light cross-offshore from the NW, so the surface will be clean. It’s surfable, but nothing to write home about. Monday afternoon is similar, with 3 feet and clean conditions.
Then we hit a dead zone. From Tuesday, August 4th, through to Saturday morning, August 8th, the swell is tiny, often under 2 feet, with poor surf conditions. The combined energy drops to single digits and low two-digit numbers. There’s just no waves to work with, even with offshore winds.
Saturday afternoon, August 8th, we see a pulse of 4 feet of SSE swell, but it’s onshore wind and the period is short at 8 seconds. The energy is moderate (167), but the conditions are poor. Not one to get excited about.
We get a little bump on Sunday, August 9th, with a 4-foot SE swell, 10-second period, and moderate energy (261). The wind is a clean cross-offshore from the NNW, so the waves will look tidy. Still just “surfable.”
The middle of the week, from Monday, August 10th to Wednesday, August 12th, is back to small, weak surf. Some sessions are clean, but the waves are just not there.
Now, here’s the one that might have you checking the forecast again. Thursday afternoon, August 13th, we’ve got a 4-foot swell from the east with a solid 12-second period. The combined energy hits 333, which is moderate. The wind is a gentle cross-offshore from the SSW, and the guidance says “expect good surf conditions.” That’s our best bet in the whole run. The water temperature is about normal for this time of year. For a point break like Avalon-North, that longer period will give the waves some shape and power. Keep an eye on this one.
Friday, August 14th, stays clean with offshore winds, but the swell is fading back to 3 feet and then 2 feet. The weekend beyond looks like it’s back to small, clean waves with no real energy.
So, to wrap it up: the standout is Thursday afternoon, August 13th. That’s your best chance for a clean, fun session with some decent energy. The rest of the window is either flat, weak, or blown out. It’s a quiet period, but that one afternoon could be a nice surprise.
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.
