The Lowdown
Alright, surfers, Rusty here. Let’s look at what’s coming up for Avalon Point.
We’re looking at a solid run of surf, but the first few days are a bit messy. The real magic starts to build towards the end of the week and into the next, with a few standout sessions that are worth blocking out time for.
The first recommendation is for Tuesday morning, the 18th of August. We’ve got a solid 12ft swell from the west, with a long 16-second period, packing a huge amount of energy (6388). The problem is a strong onshore wind, so it’s not going to be pretty. The whole day is a write-off, really. Wednesday is much the same, with strong winds and a drop in size, around 8ft to 10ft, but still messy.
Now, Thursday the 20th is where it gets interesting. The morning session is a real standout. We’ve got an 8ft swell from the WSW, still with a long 16-second period, and the wind goes glassy offshore from the northeast. This is the kind of clean, lined-up swell that makes a point break like Avalon Point sing. The wave energy is still strong (3594), and it’s going to be well-shaped. This is the call for experienced surfers who want clean, powerful waves. The afternoon gets a bit lumpy with a cross-shore wind, but the morning is the pick.
Friday the 21st is another morning gem. Similar deal: 7ft from the WSW, 15-second period, and glassy offshore easterly winds. It’s a little smaller than Thursday, but still clean and fun for those who can handle the size. The water temperature is sitting at 64°, which is about average for this time of year, so no need for a thick wetsuit.
We hit a bit of a wall over the weekend. Saturday the 22nd and Sunday the 23rd see the swell drop and the winds turn onshore or cross-shore, making for choppy, poor conditions. Monday the 24th isn’t much better.
The next big highlight comes on Wednesday the 26th of August. Another morning session with glassy conditions, an 8ft groundswell from the WSW, and a long 15-second period. The energy is still strong (2727), and it’s going to be clean and powerful. Another one for the experienced crew.
Looking further out, the forecast gets a bit more interesting, but less certain. The morning of Friday the 28th of August has a smaller, clean 5ft swell from the west with a very long 18-second period, but the real standout in the second week is a bit of a split call. The morning of the 30th of August has a 8ft swell from the west with a long 18-second period, but it’s raining. The following Monday morning, the 31st of August, sees a massive 13ft west swell, but with a cross-onshore wind, so it’ll be a beast of a wave but not clean.
However, the absolute best of the whole forecast, if you can wait for it, is Tuesday morning, the 1st of September. The forecast shows an 12ft west swell with a 16-second period, and the wind is forecast to be glassy offshore from the south-southwest. The wave energy is massive (6307), and with those conditions, Avalon Point is going to be firing with big, clean lines. This is a true standout for experts, but it’s a long way out, so keep your fingers crossed the forecast holds.
So, to sum it up: Thursday morning the 20th and Wednesday morning the 26th are your best bets in the first week. For the second week, keep an eye on the 1st of September for the potential session of the month.
Rusty out.

Information about the Avalon Point Surf forecast
The above surf forecast table for Avalon Point provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Avalon Point can be found by selecting the local surf guide option on the grey menu. Our Avalon Point 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 Point) 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 Point 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.
