Alright, Rusty here. Let’s talk about what’s shaping up for the next couple of weeks.
We’ve got a long, slow story ahead. The first good surf doesn’t roll in until Monday, July 13th, and it’s a persistent, small-scale run. No big, explosive swells, but a steady diet of clean, waist-high waves that keep on coming. The standout window is the first few days, with a couple of real gems. Before you get excited, there’s a dry spell from around Saturday, July 19th, through Sunday, July 20th morning, where the quality drops off, then it picks up again.
The main event is Big Beach. It’s a very consistent, beginner-friendly spot, but it’s fairly exposed. The water temperature is pretty much average for the time of year, nothing unusual.
The real highlight is Tuesday, July 14th. The morning is an absolute dream – glassy as a mirror, with a clean 2 ft SW swell (period 14 seconds). The combined energy is moderate (333). This is your best bet for the whole outlook. Wednesday morning, July 15th, is also a beauty, again glassy, with a 2 ft W swell, but a bit more energy (542). That’s the other standout.
The rest of the first week, from Monday afternoon through to Friday, July 17th, is still very surfable. You’re looking at 2 ft to 2 ft waves, mostly from the SW or W, with clean conditions and a gentle offshore breeze. The combined energy sits in the moderate range (279 to 494). Crowds are sometimes a thing here, so expect a few others soaking up the same clean lines.
The surf gets a bit weaker and more inconsistent from Saturday, July 18th, into the start of the next week. The quality drops, and the energy dips. By Monday, July 20th afternoon, the wind goes offshore and a 3 ft S swell starts to fill in with moderate energy (479), bringing things back to life.
From Tuesday, July 21st, through to Friday, July 24th, we’re back into a consistent run of small, clean waves. The swell is 2 ft to 3 ft from the S and SSW, with clean offshore winds. The combined energy stays moderate (277 to 452). The waves are small, so perfect for a longboard or a funboard.
The very end of the outlook, from Saturday, July 25th, slides into some smaller, more ordinary conditions. The energy drops off again, and while it’s still clean, it’s not the most exciting.
Overall, the best call is to be on the sand for Tuesday morning, July 14th, or Wednesday morning, July 15th. The rest is a solid, steady run of small but clean fun.
Rusty.

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.
