G’day, Rusty here. Let’s break down what’s on the cards for Avalon-North over the next couple of weeks.

We start a bit slow. The first real look is Saturday morning, 11 July – a 0.9m ESE swell at a clean 12 seconds, water temp about 66°F, which is normal for this time of year. The wind is a light NW cross-off, so it’s clean. But the combined swell energy is only 385 – weak to moderate – and it’s just not enough to get the heart pumping. Saturday afternoon goes cross-on and messy, so forget it.

Sunday 12 July has offshore wind, WNW at 15 mph, but the swell drops to 2ft and energy is down to 106. Surfable, but ordinary. Monday and Tuesday are basically flat – energy readings of 7 and 0 – so there’s a gap of three to four days with nothing worth paddling for.

Thursday 16 July stirs with a 7ft SSE swell, but it’s a short 7-second period, cross-shore wind, and energy at 420. Moderate energy, but the short period means it’s lumpy and junky. Friday 17 July is similar with rain and onshore winds.

Now, Saturday 18 July morning shows a light SW cross-off, a 5ft E swell at 9 seconds, and energy of 383. Clean conditions, but still building.

The big highlight is Sunday 19 July. Glassy conditions in the morning with a light NW breeze, and an 8ft E swell running at 10 seconds. Combined energy is a massive 2611 – that’s strong to very strong. This is a proper groundswell, and the point break will handle the long period well. But 8ft is big – this is for experienced surfers only. The afternoon stays glassy with ENE wind, energy still at 1496. This is the best on offer. Crowds are likely, so get there early.

Monday 20 July keeps the 8ft E swell, period stretches to 12 seconds, and energy is 2069 in the morning with WNW offshore wind. Clean and powerful. Monday afternoon goes onshore, so morning is the call. Tuesday 21 July still has 8ft to 7ft E swell, but the wind picks up and conditions get marginal.

The rest of the week drops off. Wednesday 22 July down to 6ft, Thursday 23 July at 5ft, and Friday 24 July clean with 5ft ESE – all rideable, but nothing special. Saturday 25 July afternoon shows a 6ft ESE swell with clean cross-off wind and energy of 807 – a solid session.

Bottom line: the first week is quiet until the 18th, then Sunday 19 July and Monday 20 July are the standouts – big, clean, powerful E swell. This point break loves those long-period lines, but it’s for the advanced crew only.

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.
