The Lowdown
Alright, grab your board and listen up. It’s a bit of a slow start here for the 16-day stretch, but there's some light at the end of the tunnel.
We’re looking at Big Beach, and the name is a bit of a tease for the next week or so. Things are pretty flat and ordinary for the first many days. From Tuesday the 28th of July right through until about the 7th of August, we're dealing with tiny, weak surf. The swell is barely showing its face, coming in mostly from the SSW at around 1ft to 2ft. The energy is low, generally under 300, and there's a lot of days where the wind is a bit of a pest or just not quite clean enough to make the most of what little we have. It’s the kind of period where you’d be better off tuning your fins or just going for a swim. There’s a couple of mornings and afternoons with glassy or light offshore conditions, but without the swell to back it up, it’s just a flat, clean ocean.
The water temp is sitting at about 80°F which is not far off the norm for this time of year, so that’s fine.
Finally, things start waking up on Sunday the 9th of August. The swell starts to push up, and by Monday the 10th of August, this is the standout window. We’re seeing a solid SSW groundswell building to 4ft with a period of 15 seconds, which is a very long-period groundswell. This kind of energy is going to wrap in nicely, but remember, with a period that long, it might wall up at a beach break, but Big Beach being fairly exposed should hold some nice lines. The combined energy reading on Monday morning hits 689, which is solid and powerful. The wind is light cross-off from the ENE, keeping things clean. Monday afternoon has a moderate offshore from the NE, so it should stay glassy and organised. This is the pick of the whole outlook, no question.
Tuesday the 11th of August still has some decent leftover 3ft swell but the wind gets a bit stronger and more side-on later in the day. Still, the mornings will be worth a look. The rest of that second week starts to taper off back to smaller, less consistent waves.
If you’re a beginner, the first week is safe due to the small size, but it’s not really surfable. The standout on the 10th and 11th, with waves over 2ft but under 8ft, is fine for most intermediate surfers, and the offshore winds will keep the crowds manageable, though it can get busy there sometimes.
For the kite surfers, honestly, most of the first week is a write-off for everyone. When things get windy but the surf is poor quality and small, like we see on some of those afternoons, you might get a better session on a kite, but not with the swell direction we have.
Rusty out.

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