The Lowdown

Alright, Rusty here. Let’s talk about what’s brewing out there. Right now, we’ve got a bit of a quiet spell to kick things off, but don’t write it off just yet. The first real surf we can work with shows up on Tuesday the 11th of August, with a small but clean pulse.

Tuesday morning, Avalon-North is showing a clean 2ft swell pushing in from the ENE, with a period of 9 seconds and a light offshore wind. Combined swell energy is low at 78, so it’s not packing much punch, but it’s rideable and the wind is offshore—that’ll keep the surface smooth. It’s a point break, consistent, and fairly exposed to that ENE swell direction, which lines up nicely. The water temp is sitting about average for this time of year. This is a session for the advanced crew who can make the most of small, clean lines. Tuesday afternoon stays similar with 2ft and offshore breeze, energy nudging up to 96. That’s the best we’ve got in this first block.

From Wednesday the 12th through to Saturday the 15th of August, it goes flat and poor. Swell drops to 1ft – 2ft with weak energy and cross or onshore winds. Not worth paddling out.

Sunday the 16th of August sees a jump in size—4ft in the morning building to 5ft in the afternoon—but it’s coming from the SSE with a short, weak 6-7 second period and cross-onshore wind. Combined energy hits 167-207 (moderate), but the quality is poor, choppy, and messy. This is a beach setup with the wind and short period making it tough for clean surfing. Could be more interesting for kite surfing than paddle surfing.

Monday the 17th through to Wednesday the 19th of August brings bigger swell, around 7ft to 7ft, from the SE and ESE, but again with short periods (8 seconds) and cross-onshore winds. Combined energy jumps into the 400-550 range (strong), but the wind and chop make it a no-go for decent waves. These are expert-only if anything, and even then, it’s messy.

Thursday the 20th of August drops to 4ft-5ft, still short period and cross or cross-onshore winds. Not inviting.

Then we get a glimmer. Friday the 21st of August morning, Avalon-North goes glassy. Dead calm wind, 3ft from the ENE, period 8 seconds, combined energy 129 (weak to moderate). The glassy conditions will make it look clean, but the swell is small and the energy is still low. It’s surfable but ordinary. The afternoon turns onshore, so the morning window is the one.

Saturday the 22nd and Sunday the 23rd of August are messy again with cross or cross-onshore winds and 4ft-4ft swell. Not worth it.

Monday the 24th of August morning brings a change: 3ft from the ENE with a 10-second period and offshore wind from the WNW. Combined energy is 205 (moderate). This is clean and has a bit more shape. That afternoon goes cross-off, still clean but smaller.

Now, the standout is shaping up for the end of the run. Tuesday the 25th of August shows 7ft in the morning from the SSE with a short 8-second period and cross-off wind. Energy is 635 (strong). The afternoon gets bigger to 8ft with cross-shore wind. Conditions are marginal but clean. This is big enough to be expert-only.

But the real gem is Wednesday the 26th of August morning. Avalon-North is looking at 8ft from the SE with a cross-off wind from the NNW, combined energy at 1330 (very strong). That’s a proper swell, and with clean conditions, this point break will light up. It’s a long-range call so there’s some uncertainty, but if it holds, this is the one to circle on the calendar.

Overall, don’t expect much in the first week. The best chances are the small clean window on Tuesday the 11th of August for the advanced crew, and then the big, promising swell on Wednesday the 26th of August for experts.

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.
