The Lowdown
Alright, let’s break down what’s happening at Avalon Point.
The water temp here is 65°F, which is about average for the time of year.
First up, Friday, 21 August sees a 7ft groundswell from the WSW with a long 15-second period. The wind is a light cross-off from the east at 3 mph, so the surf will be clean and powerful. This is big and long-period, so it’s for experienced surfers only. The combined energy is pumping at 2065 (moderate-strong).
Friday afternoon gets messy with the wind switching southerly and picking up to 12 mph. The swell holds at 7ft, but conditions drop off.
Saturday morning, 22 August is the real gem. The swell is a bit smaller at 7ft, but the wind is dead calm from the southeast at 3 mph – glassy perfection. The period stretches to a very long 16 seconds. Combined energy is 2068 (moderate-strong). This is the morning to be in the water.
Saturday afternoon gets wrecked by a strong 22 mph southerly wind.
Sunday morning, 23 August cleans up with a 5ft swell and a light southerly cross-off breeze. Period is 14 seconds, and the combined energy drops to 970 (moderate). Good for a cruisy session.
Monday morning, 24 August is another standout: 7ft swell, 14-second period, and glassy conditions with a 3 mph wind from the northwest. Clean, punchy, and well-shaped. Combined energy is 1570 (moderate-strong).
Through the middle of the week, the wind turns onshore, making things lumpy.
Then Wednesday afternoon, 26 August delivers a monster: 13ft swell from the west, 18-second period, and a light cross-off breeze. This is for experts only. The combined energy is a huge 8877 (strong to very strong).
Thursday morning, 27 August stays big at 10ft with a clean cross-off breeze. Combined energy 4318 (strong).
The end of August and start of September brings smaller, cleaner windows. Monday, 31 August morning is glassy with a 6ft swell, 15-second period, and no wind. Combined energy 2417 (moderate-strong).
The final standout is Saturday, 5 September with a clean 5ft morning and a light offshore breeze from the east, building to 7ft in the afternoon with a moderate offshore wind. A clean finish.
So, mark your calendar for Saturday morning, 22 August for the glassy groundswell, and Wednesday afternoon, 26 August if you’re an expert chasing a big, clean swell. Monday, 24 August is a close third.

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.
