The Lowdown
Alright, let’s look at what Avalon-North has cooking over the next couple of weeks.
Honestly, it’s a frustrating outlook. There’s a whole lot of flat, choppy, or tiny junk to sift through before anything worth paddling out for shows up. The first real chance of a surfable wave doesn’t roll in until Thursday morning, the 20th of August, and even that’s pretty average. There’s a long dry spell before that.
The only spot on the map here is Avalon-North, a point break that prefers an ENE swell. The water temp is about 63°F, which is just a touch cooler than average for this time of year – not a big deal.
From the 13th to the 19th, it’s a total write-off. The 13th has a tiny 1ft of ENE swell but it’s cross-on and choppy. Friday the 14th morning looks glassy and clean with the same tiny 1ft, but it’s barely a ripple. The weekend picks up a bit but the swell period is short – under 8 seconds – and the wind is messy. Sunday the 16th bumps up to 4ft from the ESE but with a period of only 6 seconds, so it’s windswell, and it’s choppy with cross-onshore wind. The combined wave energy hits 120 (moderate) on Sunday morning, but the quality is poor.
Monday the 17th brings onshore slop. Tuesday and Wednesday are small and unremarkable. The first week is, frankly, a loss.
Thursday morning the 20th is the first real window. It’s glassy and clean with a 3ft ESE swell at 7 seconds. The energy is weak at 87, but for this spot it’s the best we’ve got. It’s surfable but very ordinary. Not a standout.
Friday the 21st morning shapes up with 1ft of ENE swell at 8 seconds and a light cross-off wind keeping it clean. Small but clean. Saturday the 22nd morning is where it’s at: 4ft of NE swell with a clean 15 mph offshore from the west. The period is 8 seconds and combined energy is 136. That’s moderate energy, and with offshore wind that’s a big plus. Saturday the 22nd morning is the clear standout of the whole outlook – it’s the biggest clean session we get, with proper offshore conditions and the best energy reading. The swell direction is NE, which is close to the ideal ENE, so it should wrap in nice. Expect crowds at this spot.
Sunday the 23rd morning stays clean with offshore wind and a 3ft ENE swell at 9 seconds and moderate energy of 146. That’s decent too. After that, it drops sharply – Monday the 24th goes back to 1ft and stays tiny through the 28th. Some offshore days but the swell is just too small.
So the bottom line: the first week is a total dud. Your best shot is Saturday the 22nd morning – clean, offshore, with a little bit of push on the point. After that, it’s back to small stuff. Keep your fingers crossed the forecasts shift.

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.
