The Lowdown
Alright folks, it’s Rusty here. Let’s have a look at what’s on offer.
Overall, it’s a bit of a slow start and a drawn-out run of small conditions, but there’s a real pulse of energy that builds toward the end of July and into the start of August. The standout window is undoubtedly the last day of July and the first morning of August, so keep your eyes on that.
The main break is Little Avalon, a reef setup that’s advanced territory and very consistent. The water temperature is 65.1°F with the anomaly sitting at 0.7°F, so about average for the time of year.
We kick off with a Tuesday morning, July 21, but the surf is marginal. Swell is only 5ft from the ENE, period at 10 seconds, with a cross-on wind. The combined energy is moderate (433). Not worth paddling out. Tuesday afternoon and Wednesday morning are still poor, with the swell dropping and quality not there.
By Wednesday afternoon, July 22, the wind goes glassy, and the swell is 3.6ft from the ENE. It’s small but clean. The energy is moderate (210). Thursday morning, July 23, has a light cross-off breeze and a 3ft ENE swell. It’s surfable, but very ordinary. The energy drops to 121. After that, from Friday July 24 right through to the morning of Thursday July 30, the swell really bottoms out. Heights are 1.3ft or less, with combined energy figures in the single digits or low tens. It’s a long stretch of poor surf, about a week of flatness.
Then, on Friday morning, July 31, things finally wake up. Swell jumps to 5ft from the SE, period 8 seconds, with a clean offshore wind from the SW. Combined energy is 292 (moderate). The surf is clean and the forecast is good. Friday afternoon holds at 4.3ft SE, still clean. This is a solid option.
The standout is Saturday morning, August 1. Glassy conditions, a 5.2ft SE swell, period 9 seconds, and combined energy of 416 (moderate). This is the best on offer. The direction is from the SE, which matches the optimum swell direction for Little Avalon. It’s a clean, punchy morning. The afternoon falls apart quickly with a tiny 0.7ft swell and onshore wind, so get it early.
Sunday, August 2, has a 3.9ft SE swell in the morning with offshore wind, but it’s ordinary. The afternoon picks up to 4.3ft with a cross-off breeze and energy of 208. It’s rideable but not as clean as Saturday morning.
From Monday, August 3, the conditions get messy with rain and onshore winds, and the swell is mixed. The rest of the outlook drops off into small, poor surf. The best bet is glassy, clean Saturday morning, August 1, at Little Avalon.

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.
