The Lowdown
Alright, Rusty here. Let me tell you what I see coming down the line for Little Avalon.
For the best part of the next two weeks, things are looking pretty grim. Sunday the 19th sees a jump in energy with a solid 7.2ft east-northeast swell, but it's accompanied by a lumpy cross-shore wind that won't do it any favors. It's marginal at best. Monday the 20th cleans up a bit with lighter westerlies and a 5.9ft easterly swell, but the quality is still just ordinary. Then from Tuesday onwards, the swell just drops off a cliff. We're looking at a long stretch of flat, gutless conditions from midday Tuesday the 21st all the way through to the end of July. Just tiny, weak dribble that isn't worth wetting a wetsuit for.
The first real standout comes much later. Things start to get interesting on Saturday the 1st of August. The morning brings a 6.2ft south-easterly swell and light offshore winds, which is surfable. But the afternoon is the one to circle on your calendar. We get a solid 9.8ft swell from the east with an 8-second period. The combined wave energy is a beefy 1074 (moderate to strong energy) and it's paired with a light breeze keeping it clean. This is going to be proper, powerful stuff, but at that size, it's for experienced surfers only. This break is an advanced reef, so you need to know what you're doing. The water temperature is sitting at 64.6°, which is pretty average for the time of year. Don't expect any crowds that day as it’s a consistent spot that can get busy often, but the challenge will keep the numbers down.
Then carrying into Sunday the 2nd of August, the morning holds on with a 7.5ft east swell and light offshore winds. The energy is still high at 1026. It’ll still be a big, powerful wave – another day for the crew with the skills and the nerve.
Get on it for those first two days of August, but don't hold your breath for anything before that.

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