The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on offer for the next couple of weeks.
Honestly, we’re looking at a bit of a flat spell to kick things off. The first real chance to get wet is Thursday morning, July 23rd, but it’s nothing to write home about. We’ve got a small, long-period groundswell from the SSW pushing in at 3 ft, with a 20-second period. That kind of period is beautiful for a point or reef, but here at Big Beach, it can be a bit tricky. The combined energy is moderate (750), and while the wind is a cross-offshore, the call is “marginal surf.” The water’s a nice 80°, about average for this time of year, so that’s a comfort.
The real standout, the only session that’s got me excited, is Saturday afternoon, July 25th. The swell ticks up slightly to 3 ft from the SSW, still with a nice long period of 18 seconds, and the wind swings offshore. That’s the magic word. The forecast says “expect very good surf conditions” and the energy is solid (708). For a beginner-friendly spot like Big Beach, that’s about as good as it gets. It’ll be clean, lined up, and plenty of fun. Just be aware that it’s a popular spot, so expect some company.
After that little burst, the window closes fast. Sunday the 26th still has some clean, offshore waves around 3 ft to 3 ft, but it’s on the decline. By Monday the 27th, the swell is dropping to 3 ft, and the energy is fading (296). From Tuesday the 28th onward, we hit a long, dull stretch. The size drops to 2 ft, then 2 ft, and the winds go wonky – cross-onshore, cross-shore, and even a risk of thunderstorms. The energy drops into the two-digit range by the start of August. It’s a real flat spell.
We’ve got a stretch from about July 29th all the way through to August 5th with basically nothing worth paddling for. The 1 ft and 1.0 ft days are just a tease. Things perk up ever so slightly by August 6th and 7th, with a new SSW/W swell pushing 2 ft to 2 ft, and the energy climbing back up (248-333). The winds are offshore again, so it’ll be clean, but it’s tiny. For a beginner spot, it’s surfable, but not a standout.
So, mark your calendar: Saturday afternoon, July 25th, is your best bet. It’s a small window, so grab it while you can.
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.
